  SAP Error Message:
  
  WRF_APC654: Select at least one quota scale
  
  Cause:
  This error occurs in SAP when working with Production Planning and Detailed Scheduling (PP/DS) or Advanced Planning and Optimization (APO), specifically during the configuration or execution of quota arrangements in the Advanced Planning and Scheduling (APC) component.
  The message indicates that no quota scale has been selected or maintained for a quota arrangement. Quota arrangements are used to distribute demand or supply among different sources or production lines based on defined quota scales. If the system expects at least one quota scale to be assigned but finds none, it raises this error.
  
  When does it occur?
  
  During the creation or change of quota arrangements in transaction /SAPAPO/QUOTA or related planning transactions.
  When running planning heuristics or planning runs that require quota arrangements.
  When the system tries to apply quota arrangements but no quota scale is assigned or active.
  
  
  Solution:
  
  
  Check Quota Arrangement Setup:
  
  Go to the quota arrangement maintenance transaction (e.g., /SAPAPO/QUOTA).
  Verify that at least one quota scale is assigned to the quota arrangement.
  If no quota scale exists, create and assign one.
  
  
  
  Maintain Quota Scales:
  
  Define quota scales that specify the distribution percentages or quantities.
  Ensure the quota scales are valid for the planning period and relevant product/location combinations.
  
  
  
  Activate Quota Scales:
  
  Make sure the quota scales are active and valid for the current planning horizon.
  Check validity dates and ensure they cover the planning period.
  
  
  
  Check Integration:
  
  If quota arrangements are transferred from SAP ERP to APO, verify the integration and data consistency.
  Re-transfer quota arrangements if necessary.
  
  
  
  Planning Run Settings:
  
  Review the planning run or heuristic settings to ensure quota arrangements are correctly referenced.

  Summary:
