  The SAP error message MM116 indicates that the unit of measure (UoM) specified in a transaction is not defined as an alternative unit of measure for the material in question. This typically occurs in the Materials Management (MM) module when you are trying to perform an action that involves a unit of measure that is not recognized by the system for that specific material.
  Cause:
  
  Missing Alternative UoM Definition: The specified unit of measure is not set up as an alternative unit of measure in the material master record.
  Incorrect UoM Usage: The unit of measure being used in the transaction does not match any of the defined units for the material.
  Configuration Issues: There may be issues with the configuration of units of measure in the system.

  To resolve the MM116 error, you can follow these steps:
  
  
  Check Material Master Record:
  
  Go to the Material Master (Transaction Code: MM03).
  Enter the material number and select the appropriate views (e.g., Basic Data, Purchasing, or Sales).
