• What is the cause and solution for SAP error message WRF_ARTICLELIST049 - Generic subpool is full ?

  The SAP error message WRF_ARTICLELIST049: Generic subpool is full typically occurs in the context of SAP Retail or IS-Retail modules, especially when dealing with article lists or related data processing.
  
  Cause
  
  Generic subpool is full means that the memory area allocated for the generic subpool (a type of memory pool used by SAP for dynamic memory allocation) has been exhausted.
  This usually happens when a program or report tries to allocate more memory than the subpool size allows.
  In the context of SAP Retail, this can occur during processing of large article lists, promotions, or pricing data where large internal tables or complex data structures are handled.
  It can also be caused by inefficient coding or unexpectedly large data volumes being processed in one go.
  
  
  Solution
  
  
  Increase the Generic Subpool Size:
  
  The generic subpool size is controlled by the profile parameter ztta/roll_area.
  Increasing this parameter value can help allocate more memory to the generic subpool.
  To check or change this parameter:
  
  Use transaction RZ10 to edit the instance profile.
  Look for ztta/roll_area and increase its value (e.g., from 512 KB to 1024 KB or higher).
  After changing, restart the SAP instance for the change to take effect.
  
  
  
  
  
  Optimize the Program or Report:
  
  If you have custom code or user exits/enhancements involved, review them for memory usage.
  Try to process data in smaller chunks or optimize internal table handling.
  Avoid unnecessary large internal tables or complex nested loops.
  
  
  
  SAP Notes and Patches:
  
  Check for relevant SAP Notes that address memory issues or specific bugs related to WRF_ARTICLELIST049.
  Sometimes SAP releases patches or corrections for memory leaks or inefficient processing in standard programs.
  
  
  
  System Monitoring:
  
  Use transaction ST02 (Tune Summary) to monitor memory areas including the generic subpool.
  Check if the generic subpool is frequently full or if this is a one-time issue.
