• What is the cause and solution for SAP error message VH502 - Unit of measure & not available ?

  The SAP error message VH502 - "Unit of measure & not available" typically occurs in the context of handling units, deliveries, or inventory management when the system cannot find or recognize the specified unit of measure (UoM) for a material or transaction.
  
  Cause:
  
  The unit of measure (UoM) entered or used in the transaction is not defined or maintained in the system for the relevant material.
  The UoM might not be assigned or allowed in the material master data.
  The UoM might be missing in the conversion factors or unit of measure tables.
  The UoM is not valid for the specific transaction or document type.
  Possible mismatch between the UoM in the delivery or handling unit and the material master.
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to transaction MM03 (Display Material).
  Check the Units of Measure tab.
  Verify if the UoM in question is maintained as a base unit or alternative unit.
  If missing, maintain the required UoM in the material master using MM02.
  
  
  
  Maintain Unit of Measure Conversion:
  
  Use transaction CUNI or CUNI1 to maintain units of measure and conversion factors.
  Ensure that the UoM is defined and conversion factors to the base unit are maintained.
  
  
  
  Check Delivery or Handling Unit Configuration:
  
  If the error occurs during delivery or handling unit processing, verify the UoM assigned to the handling unit.
  Ensure that the UoM is consistent with the material master and delivery document.
  
  
  
  Check Customizing Settings:
  
  In SPRO, check the settings for units of measure under Logistics Execution or Inventory Management.
  Verify if any restrictions or validations are causing the UoM to be rejected.
  
  
  
  Recreate or Correct the Document:
  
  If the error occurs during document creation, correct the UoM in the document or recreate the document with the correct UoM.
