  The SAP error message RSDU_REPART679 indicates that there are historical movement requests that need to be compressed before you can convert them to a flat format. This typically occurs in the context of data warehousing, particularly when working with SAP BW (Business Warehouse) and involves the process of data extraction and loading.
  Cause:
  The error arises when you attempt to convert data requests (specifically, historical movement requests) into a flat format without first compressing them. Historical movement requests are data requests that have been loaded into the system but have not yet been compressed. Compression is necessary to optimize storage and improve performance.
  Solution:
  To resolve this error, you need to compress all historical movement requests before proceeding with the conversion. Here are the steps to do this:
  
  
  Access the Data Warehousing Workbench:
  
  Go to the SAP BW system and navigate to the Data Warehousing Workbench.
  
  
  
  Open the InfoProvider:
  
  Locate the InfoProvider (e.g., InfoCube) that contains the historical movement requests.
  
  
  
  Compress the Data:
  
  Use the transaction code RSA1 to access the Data Warehousing Workbench.
  Find the relevant InfoCube and right-click on it.
  Select the option to "Manage" or "Compress" the data.
  Follow the prompts to compress the historical movement requests.
  
  
  
  Check for Errors:
  
  After compression, check for any errors or warnings that may have occurred during the process.
  
  
  
  Retry the Conversion:
  
  Once the compression is complete, attempt to convert the historical movement requests to a flat format again.
