  The SAP error message AG860, which states "TM scheduling: Unit of measure conversion from &1 to ext. UoM failed," typically occurs in the context of Transportation Management (TM) when there is an issue with converting units of measure (UoM) during scheduling processes. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Missing Conversion Factors: The system may not have the necessary conversion factors defined for the units of measure involved. This can happen if the UoM is not properly configured in the system.
  
  
  Incorrect UoM Configuration: The UoM settings in the material master or the relevant configuration may be incorrect or incomplete.
  
  
  Inconsistent UoM Usage: There may be inconsistencies in how UoMs are used across different documents or master data, leading to conversion failures.
  
  
  Data Issues: There could be issues with the data being processed, such as missing or incorrect values that prevent successful conversion.
  
  
  Solution:
  
  
  Check UoM Configuration:
  
  Go to the transaction code CUNI (Unit of Measure Conversion) to check if the conversion factors between the involved UoMs are defined correctly.
  Ensure that the UoMs used in the transaction are set up in the system.
  
  
  
  Review Material Master Data:
  
  Check the material master data (transaction code MM03) for the relevant materials to ensure that the UoMs are correctly defined and that the conversion factors are in place.
  
  
  
  Validate Data Consistency:
  
  Ensure that the data being processed (e.g., transportation requests, shipments) is consistent and that the UoMs used are valid and correctly defined.
  
  
  
  Check Customizing Settings:
  
  Review the customizing settings for Transportation Management to ensure that all necessary configurations related to UoM are correctly set up.
