• What is the cause and solution for SAP error message RSFBP102 - Data type of field &1 does not match target (expected &2, actual &3) ?

  The SAP error message RSFBP102 indicates a data type mismatch between a field in your data source and the expected data type in the target. This error typically occurs in the context of data extraction, transformation, or loading processes, such as when using SAP BW (Business Warehouse) or during data transfer processes.
  Cause:
  The error arises when the data type of a field (denoted as &1) does not match the expected data type (denoted as &2) in the target system. The actual data type being processed is shown as &3. This mismatch can occur due to several reasons, including:
  
  Schema Changes: Changes in the source or target data model that have not been reflected in the other system.
  Data Type Definitions: Incorrect or inconsistent data type definitions between the source and target systems.
  Data Transformation Logic: Errors in the transformation logic that lead to incorrect data types being passed.
  Data Source Configuration: Misconfiguration of the data source or target settings in the data flow.
  
  Solution:
  To resolve the RSFBP102 error, you can follow these steps:
  
  
  Check Data Types: Verify the data types of the fields in both the source and target systems. Ensure that they match as expected. You can do this by checking the data dictionary (SE11) or the relevant data model definitions.
  
  
  Adjust Data Model: If there have been changes in the data model, update the target data model to reflect these changes. This may involve modifying the InfoObject or InfoProvider definitions in SAP BW.
  
  
  Review Transformation Rules: If you are using transformations, review the transformation rules to ensure that they correctly map the source fields to the target fields with the appropriate data types.
  
  
  Data Type Conversion: If necessary, implement data type conversion logic in your transformation to ensure that the data being passed matches the expected type.
  
  
  Test Data Load: After making the necessary adjustments, test the data load process again to ensure that the error has been resolved.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as sometimes bugs related to data handling can be resolved in newer versions.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary), RSA1 (Data Warehousing Workbench), and RSO2 (Manage InfoObjects) to investigate and modify data definitions.
  SAP Notes: Check SAP Notes for any known issues related to this error message. SAP Notes can provide specific guidance or patches that may resolve the issue.
  Documentation: Refer to SAP documentation for best practices on data modeling and transformation in SAP BW or other relevant modules.
