  Error Message
  WRF_APC083
  
  Text: Enter a unit of measure for material &1
  
  Cause
  This error occurs in SAP when a required unit of measure (UoM) is missing for a material in a process where the system expects it to be specified. Typically, this happens in the context of APC (Availability Check) or Product Costing where the system needs to know the unit of measure to correctly calculate quantities, costs, or availability.
  Common scenarios include:
  
  The material master record does not have a base unit of measure or the unit of measure is not maintained properly.
  During order processing or availability check, the system cannot find a valid unit of measure for the material.
  The unit of measure is missing in the BOM (Bill of Materials) or routing for the material.
  The unit of measure is not maintained in the relevant transaction or configuration.
  
  
  Solution
  To resolve this error, follow these steps:
  
  
  Check Material Master:
  
  Go to transaction MM03 (Display Material).
  Verify that the Base Unit of Measure is maintained in the Basic Data view.
  If missing, maintain it in MM02 (Change Material).
  
  
  
  Check BOM and Routing:
  
  Ensure that the unit of measure is maintained for components in the BOM.
  Check the routing for the material and verify that units of measure are correctly specified.
  
  
  
  Check Transaction Data:
  
  If the error occurs during order creation or availability check, ensure that the unit of measure is entered correctly in the transaction.
  For example, in sales orders (VA01), production orders (CO01), or planned orders, verify the UoM fields.
  
  
  
  Check Configuration:
  
  Verify that the unit of measure is defined in the system (transaction CUNI).
  Check if any custom validations or user exits are enforcing UoM entry.
  
  
  
  Re-run the Process:
  
  After correcting the unit of measure, re-execute the transaction or process that triggered the error.

  Summary
  The error WRF_APC083 indicates that the system requires a unit of measure for the specified material but it is missing or not maintained. Ensuring that the material master, BOM, routing, and transaction data have the correct unit of measure will resolve the issue.
