• What is the cause and solution for SAP error message COM_PRODUCT_UNIT012 - Not possible to convert to unit of measure & from other unit of measure ?

  The SAP error message COM_PRODUCT_UNIT012 indicates that there is an issue with converting a unit of measure (UoM) for a product. This typically occurs when the system is unable to convert a specified unit of measure to another due to missing or incorrect configuration in the unit of measure settings.
  Cause:
  
  Missing Conversion Factors: The conversion factors between the units of measure are not defined in the system.
  Incorrect Unit of Measure Configuration: The units of measure may not be correctly set up in the material master or the relevant configuration settings.
  Incompatible Units: The units of measure being used may not be compatible for conversion (e.g., trying to convert between units that are not logically convertible).
  Data Inconsistencies: There may be inconsistencies in the data related to the product or its units of measure.
  
  Solution:
  
  
  Check Unit of Measure Settings:
  
  Go to the material master (transaction code MM03) and check the unit of measure settings for the relevant material.
  Ensure that the base unit of measure and any alternative units of measure are correctly defined.
  
  
  
  Define Conversion Factors:
  
  Use transaction code CUNI to access the unit of measure conversion settings.
  Define the necessary conversion factors between the units of measure that are causing the issue.
  
  
  
  Review Material Master Data:
  
  Ensure that the material master data is complete and accurate, particularly in the Basic Data and Sales views where units of measure are defined.
