How To Fix RSTRAN569 - Rule (target field: &2 group: &3): Selected source field not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: RSTRAN - Messages for Transformation

• Message number: 569

• Message text: Rule (target field: &2 group: &3): Selected source field not possible

What causes this issue?

The selected source field cannot be used as there is a different
distribution rule, in which a different source field (&V4&) has been
chosen. As the selected source field has a rougher granularity than the
target field &V2&, the system tries to apply a time distribution. The
source field must be identical for all time distributions in the group.

System Response

An error message appears and the transformation cannot be activated.

How to fix this error?

Check the rule and select a different source field.

• What is the cause and solution for SAP error message RSTRAN569 - Rule (target field: &2 group: &3): Selected source field not possible ?

  The SAP error message RSTRAN569 indicates that there is an issue with the data transfer rules in the SAP system, specifically related to the mapping of source fields to target fields in a data transfer process (such as in SAP BW or SAP Data Warehousing). The message typically means that the selected source field cannot be used for the specified target field due to a mismatch in data types, incompatible characteristics, or other configuration issues.
  Cause:
  
  Data Type Mismatch: The source field may have a different data type than the target field, making it impossible to map them directly.
  Incompatible Characteristics: The source field may not be compatible with the target field due to the characteristics defined in the data model.
  Missing Source Field: The source field may not be available in the data source or may not be included in the data extraction.
  Incorrect Transformation Rules: The transformation rules defined in the data transfer process may not correctly specify how to map the source fields to the target fields.
  Field Length Issues: The length of the source field may exceed the length defined for the target field.
  
  Solution:
  
  Check Data Types: Verify that the data types of the source and target fields are compatible. If they are not, you may need to adjust the data types in the transformation rules.
  Review Transformation Rules: Go to the transformation rules in the SAP BW system and check the mapping for the specific target field. Ensure that the source field is correctly defined and that the mapping is valid.
  Validate Source Fields: Ensure that the source field is available in the data source and is included in the extraction process. You may need to adjust the data source or the extraction logic.
  Adjust Field Lengths: If there are field length issues, consider adjusting the lengths of the fields in the target structure or modifying the source data to fit the target requirements.
  Test the Transformation: After making changes, test the transformation to ensure that the error is resolved and that data is being transferred correctly.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to access the data model and transformation rules.
  Documentation: Refer to SAP documentation for detailed information on data transfer processes and transformation rules.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Debugging: If the issue persists, consider using debugging tools in SAP to trace the data flow and identify where the mapping fails.
  
  By following these steps, you should be able to identify the root cause of the RSTRAN569 error and implement a solution to resolve it.
