• What is the cause and solution for SAP error message WRF_APC644 - Enter a quota scale ?

  SAP Error Message:
  
  WRF_APC644 - Enter a quota scale
  
  Cause:
  This error occurs in SAP when you are working with Production Planning (PP) or Material Requirements Planning (MRP), specifically in the context of quota arrangements for procurement or production. The system expects a quota scale to be entered but it is missing or incomplete.
  A quota arrangement is used to split procurement or production quantities among different sources (e.g., vendors, plants) based on defined quotas. The quota scale defines the quantity ranges and the corresponding quota percentages.
  If the quota scale is not maintained or entered, SAP cannot determine how to split the quantities, hence it throws the error WRF_APC644 asking you to enter a quota scale.
  
  When does it occur?
  
  When creating or changing a quota arrangement in transaction MEQ1 / MEQ2 (Maintain Quota Arrangement).
  During MRP run or order creation if quota arrangements are referenced but quota scales are missing.
  When the system tries to apply quota arrangements but the scale data is incomplete or missing.
  
  
  Solution:
  
  
  Maintain the Quota Scale:
  
  Go to transaction MEQ1 (Create Quota Arrangement) or MEQ2 (Change Quota Arrangement).
  Enter the material, plant, and other relevant data.
  In the quota arrangement, ensure that the quota scale is maintained.
  
  The quota scale consists of quantity intervals and corresponding quota percentages.
  For example:
  
  0 - 100 units: 50%
  101 - 200 units: 30%
  201 - 9999 units: 20%
  
  
  
  
  Save the quota arrangement.
  
  
  
  Check Existing Quota Arrangements:
  
  Use MEQ3 to display quota arrangements and verify if the quota scale is properly maintained.
  If missing, maintain the scale as above.
  
  
  
  Verify Material Master and MRP Settings:
  
  Ensure that the material master data references the correct quota arrangement.
  Check MRP parameters to confirm that quota arrangements are correctly assigned.
  
  
  
  Re-run MRP or relevant process after maintaining the quota scale.
  
  
  
  Additional Information:
  
  Quota Arrangement (Info Record Type 3): Used to split procurement among multiple sources.
  Quota Scale: Defines how the total quantity is divided among sources based on quantity ranges.
  Transactions:
  
  MEQ1 - Create Quota Arrangement

  Summary:
  
  Cause: Missing or incomplete quota scale in quota arrangement.
  Solution: Maintain quota scale in quota arrangement via MEQ1/MEQ2.
  Result: System can correctly apply quota percentages during procurement or production planning.
