• What is the cause and solution for SAP error message VG910 - Item & (& is not assigned to an ISO unit of measure key) ?

  SAP Error Message:
  
  VG910 - Item & (&) is not assigned to an ISO unit of measure key
  
  Cause:
  This error occurs when the material/item you are trying to process (e.g., in a goods movement, delivery, or production order) does not have an ISO unit of measure (UoM) key assigned in the system. SAP requires that each material's base unit of measure be linked to an ISO unit of measure key to ensure consistent handling of units across different processes and countries.
  The ISO unit of measure key is used to standardize units according to international standards (ISO 80000 series), which helps in unit conversions, reporting, and integration with other systems.
  
  Where it happens:
  
  During goods movements (e.g., goods issue, goods receipt)
  In delivery processing
  In production order confirmations
  Any transaction that requires validation of the unit of measure against ISO standards
  
  
  Solution:
  
  
  Assign an ISO Unit of Measure Key to the Material:
  
  Go to Material Master (Transaction MM02).
  Enter the material number and select the Basic Data 1 view.
  Check the Base Unit of Measure field.
  Then, go to Additional Data or Units of Measure tab (depending on SAP version).
  Assign the appropriate ISO Unit of Measure Key to the base unit of measure.
  
  
  
  Maintain ISO Unit of Measure Keys:
  
  Use transaction CUNI (Units of Measure) or OMWN (Maintain ISO Units of Measure).
  Check if the unit of measure used for the material is assigned to an ISO unit of measure key.
  If not, assign or create the appropriate ISO unit of measure key.
  
  
  
  Check Customizing Settings:
  
  Use transaction SPRO ? Logistics General ? Units of Measure ? Check ISO Units of Measure.
  Verify that the units of measure used in your organization are properly linked to ISO keys.
  
  
  
  If the unit of measure is custom or non-standard:
  
  You may need to create a new ISO unit of measure key or map your custom unit to an existing ISO key.
  
  
  
  
  Additional Information:
  
  The ISO unit of measure key is a 2-character code that groups units of measure according to ISO standards.
  This error ensures data consistency and compliance with international standards.
  If you frequently encounter this error for multiple materials, consider running a report to identify all materials missing ISO unit assignments.
  Sometimes, this error can also occur if the unit of measure is incorrectly maintained or if there is a mismatch between the unit of measure in the transaction and the material master.
