• SAP Error Message:
  WRMA_CAT017: Allocation method requires distribution across site
  
  
  Cause:
  This error occurs in SAP when you are trying to use an allocation method that mandates the distribution of costs or quantities across multiple sites (plants), but the system detects that the distribution is not properly defined or missing. Essentially, the allocation method selected expects a site-level distribution key or rule, but such a distribution is not maintained or activated in the system.
  
  Explanation:
  
  In SAP, allocation methods are used in various modules (e.g., Production Planning, Cost Center Accounting, Warehouse Management) to allocate costs, quantities, or resources.
  Some allocation methods require that the allocation be distributed across different sites/plants.
  If the allocation method is configured to require site distribution but the distribution key or relevant master data (such as distribution rules or site assignments) is not maintained, the system throws this error.
  
  
  
  Solution:
  
  
  Check Allocation Method Configuration:
  
  Go to the configuration of the allocation method you are using.
