This error is often encountered in the context of data loading or data extraction processes, particularly in SAP BW (Business Warehouse) or SAP HANA environments.
  Cause:
  The error message RSDMD199 occurs due to the following reasons:

  Solution:
  To resolve the RSDMD199 error, you can take the following steps:
