  The SAP error message RSDS020 indicates that a data package is stored in the main memory, which can lead to issues with data processing in SAP BW (Business Warehouse). This error typically arises when there is a problem with the data loading process, particularly when the system is unable to handle the data package efficiently.
  Cause:
  
  Memory Limitations: The system may be running low on memory, causing it to struggle with processing data packages.
  Data Volume: Large volumes of data being processed at once can lead to memory overflow.
  Configuration Issues: Incorrect settings in the data loading process or in the BW system configuration can lead to this error.
