  The SAP error message L2026, which states "Unit of measure & is not maintained," typically occurs in the context of inventory management or logistics when the system encounters a unit of measure (UoM) that has not been defined or maintained in the system for a particular material or product.
  Cause:
  
  Missing UoM Definition: The unit of measure for the material in question has not been defined in the material master data.
  Incorrect UoM Usage: The UoM being used in a transaction does not match any of the UoMs defined for that material.
  Data Inconsistency: There may be inconsistencies in the data, such as changes made to the material master that have not been properly updated or saved.

  Solution:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03).
  Check the "Basic Data" and "Sales Org. Data" views to ensure that the unit of measure is defined.

  If you are using multiple units of measure, ensure that the conversion factors between them are correctly defined.

  If the error occurs during a specific transaction (e.g., goods receipt, sales order), review the transaction data to ensure that the correct UoM is being used.
  
  
  
  Configuration Settings:
