• What is the cause and solution for SAP error message RSBBS203 - Source selection for &1 is incompatible for target selection ?

  The SAP error message RSBBS203 indicates that there is an incompatibility between the source selection and the target selection in a data transfer process, typically in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error usually arises when trying to transfer data from a source (like an InfoProvider) to a target (like a DataStore Object or InfoCube) where the characteristics or key figures do not match or are not compatible.
  Cause:
  
  Incompatible Structures: The structure of the source and target objects may not match. For example, if the source has a characteristic that the target does not, or if the data types of corresponding fields do not align.
  Missing Key Figures or Characteristics: The target selection may require certain key figures or characteristics that are not present in the source selection.
  Data Source Configuration: The configuration of the data source may not be set up correctly, leading to mismatches in the expected data structure.
  Transformation Rules: If there are transformation rules defined that do not align with the source and target structures, this can lead to incompatibility.
  
  Solution:
  
  Check Source and Target Structures: Verify that the structures of the source and target objects are compatible. Ensure that all required characteristics and key figures are present in both the source and target.
  Adjust Transformations: Review the transformation rules between the source and target. Make sure that the mappings are correct and that all necessary fields are included.
  Modify Data Source: If the data source is not configured correctly, adjust the settings to ensure that it aligns with the target structure.
  Use the Right InfoObjects: Ensure that the InfoObjects used in the source and target are the same and have compatible attributes.
  Test Data Transfer: After making adjustments, test the data transfer again to see if the error persists.
