• What is the cause and solution for SAP error message M2687 - No self-defined unit found. Processing terminated ?

  The SAP error message M2687 "No self-defined unit found. Processing terminated" typically occurs in the context of materials management or inventory management when the system cannot find a specific unit of measure (UoM) that has been defined for a material. This can happen during various processes, such as when creating or processing purchase orders, sales orders, or inventory transactions.
  Cause:
  
  Missing Unit of Measure: The unit of measure that is being referenced in the transaction is not defined in the system.
  Incorrect Configuration: The material master data may not have the correct units of measure set up, or the unit of measure may not be assigned to the material.
  Custom Units: If you are using custom or self-defined units of measure, they may not be properly configured in the system.
  Data Inconsistency: There may be inconsistencies in the data, such as missing entries in the unit of measure tables.
  
  Solution:
  
  
  Check Material Master: 
  
  Go to the material master record (transaction code MM03) and check the units of measure defined for the material. Ensure that the required unit of measure is listed.
  If the unit of measure is missing, you can add it using transaction code MM02 (Change Material) or MM01 (Create Material).
  
  
  
  Define Units of Measure:
  
  If you need to create a new unit of measure, you can do this in the configuration settings. Use transaction code CUNI to access the unit of measure configuration and define the necessary units.
  
  
  
  Check Custom Units:
  
  If you are using custom units, ensure that they are properly defined in the system. You may need to consult with your SAP configuration team to verify that the custom units are set up correctly.
  
  
  
  Review Configuration:
  
  Check the configuration settings for units of measure in the SAP IMG (Implementation Guide). Navigate to:
  
  Logistics -> General -> Material Master -> Basic Settings -> Units of Measure
  
  
  Ensure that the settings align with your business requirements.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on your material master data to identify any discrepancies that may be causing the issue.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for additional guidance on handling unit of measure issues.
