You can convert Any datatype to any other type. Only restictions with Time and Date whcih are not compatible with each other. Depending on the data type of the field, there is a conversion when the contents of a screen field are converted from display format to SAP-internal format and vice versa. If this standard conversion is not suitable, it can be overridden by defining a conversion routine in the underlying domain.
Conversion routines are identified by a five-place name and are stored as a group of two function modules. The function modules have a fixed naming convention.
The following function modules are assigned to conversion routine xxxxx:. A conversion means data that is converted from one format to another format tshirt con fondo grezzo e tasca ombre blue 7xs3uxmx from one system to another. So when you first implement SAP, you are actually replacing some of your legacy systems, but you are not completely trashing the data.
You still need some of that data from the systems that are being replaced. So you pull the data out of your legacy systems and put them on some files. You then want to load that data into your new SAP system.
That is when you write some programs which will read that data and load it into SAP. Imagine you had a home grown purchasing system. You are now replacing all that with SAP. But until SAP goes live, you want to keep using your home grown purchasing system. So you convert the data. There are ten predefined ABAP data types.
There are possible type combinations between these elementary data types. ABAP supports automatic type conversion and length adjustment for all of them except type D date and type T time fields which cannot be converted into each other.
The following conversion tables define the rules for converting elementary data types for all possible combinations of source and target fields.System conversion from SAP ECC to S/4 HANA (Finance Configuration)- SAP ERP Central Component (ECC)
The target field is filled from left to right. If it is too long, it is filled with blanks from the right. If it is too short, the contents are truncated from the right.
The contents of the source field must be a valid representation of a type F field as described in Literals. Only the digits in the source field are copied. The field is right-justified and filled with trailing zeros. The source field must contain the representation of a decimal number, that is, a sequence of digits with an optional sign and no more than one decimal point. The source field can contain blanks. If the target field is too short, an overflow may occur. This may cause the system to terminate the program.
Since the character field must contain a hexadecimal string, the only valid characters are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. This string is packed as a hexadecimal number, transported left-justified, and filled with zeros or truncated on the right. The date is converted into a packed number. The packed number is then converted into a floating point number see corresponding table. The date is transported left-justified without conversion and, if necessary, filled with zeros on the right.
The value of the mantissa lies between 1 and 10 unless the number is zero. The exponent is always signed.In such a scenario we can easily create a Currency Translation table in SAP Analytics Cloud and then leverage the information to allow for a Currency Conversion in our stories.
For SAP Analytics Cloud to be able to provide the ability to translate data from one currency to another, you will have to configure the source currency in your data, as well as you will have to setup the Currency Translation table with the details on the valid period and the translation details. For our example we will use a relatively simple data set and we will configure the source currency in the model in SAP Analytics Cloud.
Our source data contains a dimension for an Order ID, an Order Date, a dimension for the Country, and a dimension for the Currency as well as a measure for the Order Value.
Our Currency Translation table will need to have entries to cover the timeline as well as those currencies as source and target currencies. In the last few steps we create a model and uploaded data with values for three different currencies. We also created a currency translation table and enabled the currency conversion in the model.
We have now all the information, so that we can create a story in the next set of steps and use the newly modeled information. Is it always necessary to give currency dimension? Technical Articles.

SAP S/4HANA Conversion Complication Factors
Figure 3: Data Management Use the disk symbol in the General menu to save the changes. Select the option New Currency Conversion Table. Enter CurrencySample as Name and Description.Introduction :. I would like to share my experience in data conversion process with the SAP community. Data conversion is one of the most critical processes in successful SAP implementation projects.
Step 4: final preparation. Step 5: go live. I have also heard of SAP projects in which the Basis team has carried out this process. The data converted is used only in order to set up master data in ECC. External tool named Process runner which communicates easily with ECC. I used Process runner which was purchased by my company.
Two of the most important qualities which are required in order to succeed in this process are : 1. Thoroughness 2. As mentioned above, data conversion process is part of the realization step.
After the approval, the implementers start to customize and writing down specification documents for new developments in the Development area in ECC. Only then, its possible to start the data conversion process. There are sub steps in data conversions:. Mapping the necessary fields in the ECC object that will be filled with data I. E: Equipment object in PM module. Here you need to be well aware of what is written in blueprint documents regarding your SAP objects.
Some times object classification is needed. This happens when object regular fields are not enough to store entire data from legacy system. I used classification in equipment object that represented electric generators.
Creating one instance master data manually. The purpose of this step is to verify that the implementer is able to create master data manually before conducting the recording. In case the recording is not accurate, or changes in setting up the master data are need to be done after recording, the recording has to start all over again.
Thus it is important for you to be certain how to set up the objects master data correctly.You use this function to convert quantities in data records, returned by a data provider into a given target unit of measure, using conversion factors. The result data contains at least one quantity column and a corresponding unit of measure column that are linked together.
Appropriate conversion factors from the original to the target unit of measure are available. The system triggers unit of measure conversions during query processing.
Therefore, each request for a unit of measure conversion requires the re-execution of the query, including a new data retrieval from the data provider. The unit of measure conversion is executed in the system BCV is used in, and not necessarily the system the data is read from. If you have not set up the system landscape automated update of the conversion factor table properly, the conversion factors can differ between the different systems.
For more information, see Definition of Queries. Columns that contain quantities refer to query fields of data type QUAN.
Columns that contain units of measure refer to query fields of data type UNIT. To allow unit conversions, you must link a a quantity column to the corresponding unit of measure column. If the information about the conversion material the material for which the conversion factor is defined is also available in the result data, a link can be created, too.
Columns that contain conversion materials refer to query fields of textual data type. To provide the conversion material for currency conversions, you must link the unit of measure column to the corresponding conversion material column.
You can do this when defining a search connector, or a BCV query, by assigning the respective textual field as reference field to the UNIT field and setting the reference type to Conversion Material. The system uses this field to pass the conversion target to the BCV query. You can either set it to a fixed value in the query view definition see Definition of Query Views or let the system fill them from your input at runtime.
To perform the unit of measure conversion, conversion factors from the original unit of measure to the target unit of measure must exist in the BCV system. For units without dimension EA, PAL, ROL, and so on that can only be converted in a material-dependent way, the conversion factors also depend on the conversion material. In such a case, a conversion factor for the respective material must exist. These tables only contain conversion factors for units with dimension that is, for material-independent conversions.
You are responsible for providing the conversion factors and for the completeness and correctness of this information. This means that the system performs unit of measure conversion before formula calculations, grouping, aggregation, and sorting of the result data.
In the result data, the system converts the values of all quantity columns that are linked to a corresponding unit of measure column. The only exceptions are quantity columns where you have selected the No Conversion checkbox in the corresponding query field.
When the conversion of a value was successful, the system replaces the original value of the quantity column with the converted value. Furthermore, it replaces the original unit of the corresponding unit of measure column with the target unit.
Due to the unit of measure update logic described above, you cannot have two quantity columns linked to the same unit of measure column where one of the quantity columns has the No Conversion checkbox selected.
If the conversion of a quantity fails because of an invalid unknown original unit of measure, missing material information for material-dependent conversionsor a missing appropriate conversion factor, the system raises an exception and the BCV query does not return any result data.
For more information about the use of the context key, see Context Key. At runtime, the system determines the active implementation of the BAdI whose filter value matches the current application.
Depending on the source of conversion factors you used in the BAdI implementation, you have to provide appropriate conversion factor information at the respective place. For more information, see section Determination of Conversion Factors above. Prerequisites BCV allows unit of measure conversions if the following apply: The result data contains at least one quantity column and a corresponding unit of measure column that are linked together.
You have specified a target unit of measure. Note The system triggers unit of measure conversions during query processing.
SAP BAPI Tutorial - Step by Step Guide to Create BAPI in ABAP
End of the note. Note The unit of measure conversion is executed in the system BCV is used in, and not necessarily the system the data is read from. Determination of Conversion Factors To perform the unit of measure conversion, conversion factors from the original unit of measure to the target unit of measure must exist in the BCV system.You use this function to convert currency amounts in BCV.
Currency conversion is possible into a given target currency unit in data records returned by a data provider, with the exchange rate of a given exchange rate type valid at a given conversion date. The exchange rate type specifies which of the different exchange rates buyer, seller, average, fixed, and so on the system uses for the conversion.
The result data contains at least one currency amount column and a corresponding currency unit column that are linked together. You have specified the target currency unit and, possibly, an exchange rate type, as well as a conversion date. You have specified appropriate exchange rates from the original to the target currency unit.
The system triggers currency conversions during query processing. Therefore, each request for a currency conversion requires the re-execution of the query, including a new data retrieval from the data provider.
The unit of currency conversion is executed in the system BCV is used in, and not necessarily the system the data is read from. If you have not set up the system landscape automated update of the conversion factor table properly, the conversion factors can differ between the different systems. For more information, see Definition of Queries. Columns that contain currency amounts refer to query fields of data type CURR. Columns that contain currency units refer to query fields of data type CUKY.
To allow currency conversions, a currency amount column has to be linked to the corresponding currency unit column. If information about the conversion date the date on which the exchange rate is defined is also available in the result data, a link can be created to this information, as well. Columns that contain conversion dates refer to query fields of data type DATS. To provide the conversion date for currency conversions, you must link the currency unit column to the corresponding conversion date column.
Target Currency Unit. Exchange Rate Type. The system uses these fields to pass the concrete conversion target on to the BCV query. You can either set them to fixed values when defining a query view see Definition of Query Views or fill them from your input at runtime.
For more information about these tables, see SAP Note To be able to convert from currency unit A to currency unit B, the system must know either a direct exchange rate from A to B, or an exchange rate from A to C, and from C to B where C is the base currency unit assigned to the exchange rate type. If no exchange rate exists for the given conversion date, the system uses the next most recent exchange rate. BCV is neither responsible for providing the exchange rate data in the BCV system nor for checking the completeness, correctness, and timeliness of this data.
Both tasks are the responsibility of the user. Missing or inaccurate data may result in erroneous query results. This means that the system performs currency conversion before formula calculations, grouping, aggregation, and sorting of the result data.The database structure of a table can be adjusted to its changed ABAP Dictionary definition in three ways:. If the table does not contain any data, the existing table is deleted in the database and recreated.
It is possible for you to convert cluster table to transparent table. But it is recommended to convert all cluster tables in the same table cluster to be transparent, not only part of them.
The standard table conversion via T-cd:SE14 cannot convert an entire table cluster and make all contained cluster tables transparent. Instead, the change has to be done cluster table by cluster table. While a single cluster table is being converted, it must not be updated because basically the entire conversion is downtime.
The problem is that there is no mechanism during a cluster table conversion that prevents update accesses during the conversion. If the cluster table is updated by the application during the conversion, the result is undefined, i.
And because there are huge data contained in cluster tables, pay attention to make sure there are enough space on database. If you already converted cluster tables into transparent tables, pay attention not to convert them back into cluster tables during next upgrade.
It is very important that you should not skip SPDD adjustment for these tables. Otherwise these table will be converted back to cluster table during upgrade. It is suggested to double check the inactive version of the tables during upgrade in the shadow system before starting the activation phase. During upgrade, the active version in the shadow system will show these tables as cluster tables, and inactive version as transparent ones.
The inactive version is the one that will be active after the activation phase. In case the inactive version is not OK or does not exist, it has to be adjusted or created by changing the table in the shadow system in transaction SE Table unlock from conversion will lead to dictionary object inconsistencies, so normally it is not recommended to unlock a table from conversion. Cluster table BSEG contains financial accounting documents which usually contain a lot of data records, generally the conversion on table BSEG takes an extremely long time sometimes several days or terminates.
Unfortunately we still can find some conversion issues that happened on table BSEG. If BSEG conversion already started, always it is too late to stop it for example if step2 already finished. So it makes sense to ensure that BSEG conversion will not be triggered beforehand. It is SAP design, not a problem. The reason is that one or some table fields were changed from Character type to Number type which triggered table conversionand the table contains data which are not compatible with this change.
Generally it was caused by wrong operation, so it is necessary to roll back the conversion. If step 2 has already been completed, you have to continue the conversion. Generally the runtime will be extremely long.This document is intended to serve as a guideline for creation of a new unit of measure and its related issues. Definition - Unit of Measure is the criterion based on which you measure the quantity of the material. Unit of measure is a value for a physical size.
These UoM's are linked with each other for every material by conversation table which is explained below in section - IV-alternative unit of measure. It's a onetime creation during the project phase and it used across all modules. Decide under which dimension unit has to be created:.
There are seven base dimensions, to which all other dimensions can be traced: Length, weight, time, electrical current, temperature, molecular mass and brightness. Whenever unit of measurement is to be created first decide to which dimension it belongs to or otherwise UOM is created under no dimensions. Dimension helps us to group the UOMs. System will allow to create business specific dimensions but always it is advisable to create UOM under the above 7 dimensions.
Decide which ISO code should be assigned to the unit:. It is used for converting the SAP-internal units of measurement into standard units of measurement. A list of the current international ISO codes for units of measurement is available on the Internet at:. Select the particular dimension under which you want create the unit as shown below.
Ex:TIME 4. S is the SI unit in this dimension 5. Click on create button. Maintain the details like Measurement text, commercial name and technical name. Maintain the conversion factor with respect to SI unit. For example here In H unit of measure, conversion is defined with respect to S second. Maintain the decimal places up to which decimal value should display and decimal place rounding up to which the value should be rounded off.
Maintain the tick for commercial unit check box if that unit is used commercially. It will make this unit get displayed in F4 help for unit of measure.
Maintain the tick for Value based check box if that unit will be derived based on value. If it is based on quantity, check box should not have a tick. If the same ISO code is used for more than one unit of measure, you can only flag one unit of measure as a primary unit for one ISO code. Rest of unit of measure will be the secondary unit for this ISO code. Instead of deleting Unit of measure, In CUNI transaction Commercial measuring unit tick is removed so that it will not be displayed in F4 search help for UOM and also whenever it is used in any transaction it will give an Error as "unit is not defined as commercial unit" SAP always go by commercial name.
Individual departments may have their own units of measure. For example, Purchasing may use a different unit than Sales and production may issue a material which is different than the base unit of measure.
All units of measure other than the base unit of measure are referred to as alternative units of measure. It is defined in Basic data view in material master. All other units defined, conversion should be maintained with respect to unit of measure in Material master additional data.
It is defined in sales view of material master.
