  The SAP error message RSDHA402, which states "ABAP type '&1' not supported," typically occurs in the context of data modeling or when working with InfoObjects in SAP BW (Business Warehouse). This error indicates that there is an issue with the data type of a field or object that is not compatible with the expected ABAP types in the system.
  Cause:
  
  Unsupported Data Type: The error usually arises when a field or InfoObject is defined with a data type that is not recognized or supported by the ABAP environment. This can happen if the data type is custom or if there is a mismatch between the data type defined in the source system and what is expected in SAP BW.

  Check Data Types: Review the data types of the fields in the source system and ensure they are compatible with the ABAP types supported by SAP BW. Common ABAP types include CHAR, NUMC, DATS, TIMS, etc.
  Modify InfoObject Definition: If you have control over the InfoObject definition, consider changing the data type of the InfoObject to one that is supported by ABAP.
  Adjust Data Source: If the issue is with a data source, you may need to adjust the extraction logic or modify the data source to ensure that the data types are compatible.
  Use Transformation Rules: If you are using transformations, ensure that the mapping between source fields and target InfoObjects is correctly defined, and that any necessary type conversions are applied.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance on the data types supported in your version of SAP BW.
