• What is the cause and solution for SAP error message RS_DB_DB6603 - PSA table is column-organized ?

  The SAP error message RS_DB_DB6603 indicates that you are trying to perform an operation on a Persistent Staging Area (PSA) table that is column-organized, which is not supported for certain operations. This error typically arises in the context of data extraction and loading processes in SAP BW (Business Warehouse) or SAP HANA environments.
  Cause:
  The error occurs because the operation you are attempting to perform is not compatible with the columnar storage format of the PSA table. Column-organized tables are optimized for read operations and analytical queries, but certain data manipulation operations (like updates or deletes) may not be allowed or may require different handling.
  Solution:
  To resolve this error, consider the following approaches:
  
  
  Check Operation Compatibility: Ensure that the operation you are trying to perform is compatible with column-organized tables. If the operation is not supported, you may need to adjust your approach.
  
  
  Use Row-Organized Tables: If your use case requires frequent updates or deletes, consider using a row-organized table instead of a column-organized table for the PSA. This may involve changing the data model or the way data is staged.
  
  
  Data Loading Process: Review the data loading process to ensure that it is correctly configured for the type of table you are working with. If you are using a transformation or data flow that is not compatible with columnar storage, you may need to modify it.
  
  
  SAP Notes and Documentation: Check for any relevant SAP Notes or documentation that may provide additional insights or updates regarding this error. SAP frequently updates its systems, and there may be specific patches or recommendations available.
  
  
  Consult SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP Support for assistance. They can provide guidance based on the specific context of your system and the operations you are trying to perform.
