• What is the cause and solution for SAP error message VH141 - Unit of measurement & is not assigned to material master record & ?

  SAP Error Message:
  
  VH141 - Unit of measurement & is not assigned to material master record &
  
  Cause:
  This error occurs when you try to use a unit of measurement (UoM) in a transaction or process that is not assigned or maintained in the material master record for the material in question.
  In SAP, each material master record has specific units of measure assigned to it, such as Base Unit of Measure (Base UoM), Sales Unit, Purchase Unit, or other alternative units. If you attempt to post a transaction (e.g., goods movement, sales order, purchase order) using a unit of measure that is not defined or allowed for that material, SAP throws this error.
  
  Explanation:
  
  The system checks if the unit of measure used in the transaction is valid for the material.
  If the unit is missing in the material master (in the relevant UoM fields or alternative units), the system cannot process the transaction.
  This ensures consistency and prevents errors in inventory management, sales, and purchasing.
  
  
  Solution:
  
  
  Check the Material Master:
  
  Use transaction MM03 (Display Material) or MM02 (Change Material).
  Go to the Basic Data 1 view to check the Base Unit of Measure.
  Check other relevant views depending on the process (e.g., Sales: Sales Org. Data 1 for sales units, Purchasing for purchase units).
  
  
  
  Assign the Unit of Measure:
  
  If the unit of measure you want to use is missing, add it to the material master.
  For example, in MM02:
  
  Go to the relevant view (Sales, Purchasing, Basic Data).
  Add the required unit of measure in the appropriate field.
  
  
  Save the changes.
  
  
  
  Alternative Units of Measure:
  
  If you want to use an alternative unit of measure (e.g., carton, box), maintain it in the Additional Data or Units of Measure tab.
  This allows conversion between base unit and alternative units.
  
  
  
  Check Transaction Data:
  
  Ensure that the unit of measure entered in the transaction matches one of the units assigned to the material.

  Notes:
  
  Always maintain consistent units of measure to avoid conversion errors.
  If you frequently use alternative units, maintain them properly in the material master.
  Check if the unit of measure is valid in the client and plant context.
