• What is the cause and solution for SAP error message RSD_TREX171 - No compression possible with BWA InfoCube '&1' ?

  The SAP error message RSD_TREX171 indicates that there is an issue with the compression of a BWA (Business Warehouse Accelerator) InfoCube. This error typically arises when the system is unable to compress the data in the InfoCube due to certain conditions not being met.
  Cause:
  
  Data Structure Issues: The InfoCube may have a data structure that does not allow for compression. This can happen if there are inconsistencies in the data or if the InfoCube is not properly defined.
  Data Volume: If the volume of data in the InfoCube is too low, the system may determine that compression is not necessary or possible.
  Data Locks: If there are active data locks on the InfoCube, it may prevent the compression process from executing.
  Incompatible Data Types: Certain data types or characteristics may not be compatible with the compression process.
  Technical Settings: The technical settings of the InfoCube may not be configured correctly for compression.
  
  Solution:
  
  Check Data Structure: Review the structure of the InfoCube to ensure that it is correctly defined and that there are no inconsistencies in the data.
  Data Volume: Ensure that there is sufficient data in the InfoCube. If the data volume is low, consider loading more data before attempting compression.
  Release Locks: Check for any active locks on the InfoCube and release them if necessary. You can use transaction codes like SM12 to check for locks.
  Review Data Types: Ensure that all data types and characteristics in the InfoCube are compatible with the compression process.
  Technical Settings: Review the technical settings of the InfoCube in the Data Warehousing Workbench (transaction RSA1) to ensure they are configured correctly for compression.
  Rebuild the InfoCube: If the above steps do not resolve the issue, consider rebuilding the InfoCube. This can be done by deleting the existing data and reloading it.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) and SM12 (Display and Manage Locks) to manage InfoCubes and check for locks.
  SAP Notes: Check for relevant SAP Notes that may provide additional insights or patches related to this error.
  Documentation: Refer to SAP documentation for detailed information on InfoCubes, compression processes, and troubleshooting steps.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with SAP support or your technical team for further assistance.
