• What is the cause and solution for SAP error message RSDU_REPART681 - Compress request &1 before converting InfoCube &2 to flat ?

  The SAP error message RSDU_REPART681 indicates that there is a need to compress a request before converting an InfoCube to a flat format. This typically occurs in the context of data extraction or reporting in SAP BW (Business Warehouse).
  Cause:
  The error arises when you attempt to convert an InfoCube to a flat file format (for example, during data extraction or reporting) without first compressing the data in the InfoCube. The compression process is necessary to optimize the storage and performance of the InfoCube, and it ensures that the data is in a suitable state for conversion.
  Solution:
  To resolve this error, you need to perform the following steps:
  
  
  Compress the InfoCube:
  
  Go to the SAP BW system.
  Navigate to the InfoCube that is causing the error.
  Use the transaction code RSA1 to access the Data Warehousing Workbench.
  Find the InfoCube in the "Modeling" section.
  Right-click on the InfoCube and select the option to "Compress" the data.
  Follow the prompts to complete the compression process.
  
  
  
  Re-attempt the Conversion:
  
  After successfully compressing the InfoCube, try to convert the InfoCube to a flat file format again.
  Ensure that the data is now in a state that allows for successful conversion.
  
  
  
  Related Information:
  
  Compression in SAP BW: Compression is a process that reduces the size of the data stored in an InfoCube by removing duplicates and aggregating data. This is essential for performance optimization and efficient data retrieval.
  Transaction Codes:
  
  RSA1: Data Warehousing Workbench
  RSD1: InfoObject maintenance
  RSD2: InfoProvider maintenance
  
  
  Best Practices:
  
  Regularly monitor and compress InfoCubes to maintain optimal performance.
  Schedule compression jobs during off-peak hours to minimize impact on system performance.
  Keep an eye on the data load process to ensure that data is being compressed as needed.
  
  
  
  If you continue to experience issues after following these steps, it may be beneficial to consult with your SAP Basis or BW administrator for further assistance.
