• What is the cause and solution for SAP error message WFCS151 - Base qty is 0 for internal production for material &1, plant &2 &3 &4 ?

  The SAP error message:
  WFCS151: Base qty is 0 for internal production for material &1, plant &2 &3 &4
  
  Meaning / Cause:
  This error occurs during production order processing or confirmation when the system tries to calculate or use the base quantity for internal production, but the base quantity is found to be zero. The base quantity is essential for determining the quantities of components or operations in production.
  Possible causes include:
  
  The base quantity in the material master (usually in the MRP 1 or Work Scheduling view) is set to zero or missing.
  Incorrect or missing BOM (Bill of Materials) or routing data that leads to zero quantity calculations.
  The production order or process order references a material or plant combination where the base quantity is not maintained.
  Customizing or user-exits that manipulate quantities incorrectly.
  Data inconsistencies or master data errors.
  
  
  Where it occurs:
  
  During production order creation or confirmation.
  When the system tries to calculate component requirements or capacity based on the base quantity.
  In internal production scenarios where the system expects a valid base quantity.
  
  
  Solution / How to fix:
  
  
  Check the Material Master:
  
  Go to transaction MM03.
  Enter the material &1 and plant &2.
  Check the Work Scheduling view (view 41).
  Verify the Base Quantity field. It should be greater than zero.
  If it is zero or missing, maintain a valid base quantity (usually 1 or the standard production lot size).
  
  
  
  Check BOM and Routing:
  
  Use transaction CS03 to check the BOM for the material.
  Ensure that the quantities in the BOM are correct and consistent.
  Use transaction CA03 to check the routing.
  Verify that the routing is assigned correctly and that the quantities and operations are valid.
  
  
  
  Check Production Order:
  
  Review the production order to ensure it references the correct material and plant.
  Check if the order type and production type are correctly set for internal production.
  
  
  
  Check Customizing:
  
  Verify if any user-exits, BADIs, or enhancements are modifying quantities.
  Check if any custom logic is causing the base quantity to be zero.
  
  
  
  Recreate or Correct Master Data:
  
  If master data is corrupted or incomplete, recreate or correct the material master, BOM, or routing.
  
  
  
  Consult SAP Notes:
  
  Search SAP Support Portal for notes related to WFCS151 for any known bugs or patches.
  
  
  
  
  Additional Information:
  
  The base quantity is a key parameter in production planning and execution. It defines the quantity of the material for which the BOM and routing are valid.
  A base quantity of zero is invalid and causes calculation errors.
  This error is common when materials are newly created but not fully maintained.
  Always ensure master data consistency before creating production orders.
