• What is the cause and solution for SAP error message RSMDS002 - Internal data type '&1' is not supported ?

  The SAP error message RSMDS002 indicates that there is an issue with the internal data type being used in a DataSource or during data extraction. The message states that the internal data type specified (represented by &1) is not supported by the system.
  Cause:
  
  Unsupported Data Type: The error typically arises when the DataSource is trying to use a data type that is not recognized or supported by the SAP system. This can happen if the DataSource is configured incorrectly or if there are changes in the underlying data structure that are not reflected in the DataSource.
  DataSource Configuration: If the DataSource is custom or has been modified, it may be using a data type that is not compatible with the extraction process.
  Version Mismatch: Sometimes, this error can occur due to version mismatches between the source system and the target system, especially if the DataSource is being used in a different version of SAP.
  
  Solution:
  
  Check DataSource Configuration: Review the configuration of the DataSource in transaction RSA1 (Data Warehousing Workbench). Ensure that the data types used in the DataSource are supported by SAP.
  Update DataSource: If the DataSource is custom, consider updating it to use supported data types. You may need to adjust the field definitions in the DataSource to align with the supported types.
  Recreate DataSource: If the DataSource is not functioning correctly, you might consider deleting and recreating it, ensuring that you use the correct data types during the setup.

  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the supported data types and any limitations that may apply.
  Testing: After making changes, test the DataSource extraction to ensure that the error is resolved.
