• What is the cause and solution for SAP error message RSDME116 - &1 and &2; data type mismatch ?

  The SAP error message RSDME116 indicates a data type mismatch in the context of data extraction or transformation processes, particularly in SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error typically occurs when there is an inconsistency between the data types of fields in the source system and the target data model in SAP BW.
  Cause:
  
  Data Type Mismatch: The most common cause is that the data type of a field in the source system does not match the expected data type in the target InfoObject or DataStore Object (DSO) in SAP BW. For example, a field might be defined as a character type in the source but as a numeric type in the target.
  Field Length Issues: Sometimes, the length of the data in the source system exceeds the defined length in the target InfoObject.
  Transformation Rules: If there are transformation rules defined that attempt to convert data types incorrectly, this can also lead to mismatches.
  Changes in Source Structure: If the structure of the source data has changed (e.g., new fields added, data types changed) and the BW model has not been updated accordingly, this can lead to errors.
  
  Solution:
  
  Check Data Types: Review the data types of the fields in both the source system and the target InfoObject/DSO. Ensure that they match. You can do this by checking the data element definitions in the ABAP Dictionary (SE11).
  Adjust Transformation Rules: If there are transformation rules that are causing the mismatch, adjust them to ensure that the data types are compatible. You can do this in the Transformation maintenance (RSA1).
  Modify InfoObject/DSO Definitions: If necessary, modify the definitions of the InfoObjects or DSOs in BW to match the data types from the source system.
  Field Length Adjustments: If the field lengths are causing issues, consider adjusting the lengths in the target InfoObject/DSO to accommodate the data from the source.
  Re-activate Objects: After making changes, ensure to re-activate the InfoObjects, DSOs, and transformations to apply the changes.
  Test Data Load: After making the necessary adjustments, perform a test data load to ensure that the error has been resolved.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to manage InfoObjects, DSOs, and transformations.
  Data Dictionary: Use SE11 to check the definitions of data elements and domains.
  Error Logs: Check the error logs in the Data Transfer Process (DTP) for more detailed information about the error.
  SAP Notes: Look for relevant SAP Notes that may provide additional insights or solutions for specific scenarios related to this error.
  
  By following these steps, you should be able to identify and resolve the data type mismatch error in SAP BW.
