  WRF_APC656 - Select a different purchasing list
  
  Cause:
  This error typically occurs in the context of Advanced Planning and Optimization (APO) or Supply Chain Management (SCM) when the system is unable to process the current purchasing list due to inconsistencies or conflicts. The purchasing list might be locked, outdated, or contains data that cannot be processed further (e.g., due to changes in master data, planning versions, or system inconsistencies).
  Common causes include:  
  
  The purchasing list is already processed or locked by another user or process.

  The system requires a different purchasing list because the current one does not meet the criteria for the operation (e.g., planning run, order creation).

  Select a Different Purchasing List:
  
  Follow the message instruction and select a different purchasing list that is valid and available for processing.

  If the purchasing list is outdated, regenerate it using the appropriate planning or list generation transaction.  
  Ensure that the master data and planning parameters are consistent and up to date.
  
  
  
  Check Planning Version and Parameters:  
  
  Confirm that the planning version and selection parameters used to generate the purchasing list are correct and consistent with the current system state.
