• What is the cause and solution for SAP error message CMMOI_TSW_RISK019 - UoM conversion from & to & failed for material & ?

  The SAP error message CMMOI_TSW_RISK019 indicates that there is a failure in the unit of measure (UoM) conversion for a specific material. This error typically occurs in the context of materials management, particularly when dealing with transactions that involve different units of measure.
  Cause:
  
  
  Missing UoM Conversion: The primary cause of this error is that there is no defined conversion factor between the two units of measure involved in the transaction. For example, if you are trying to convert from kilograms to pounds, and there is no conversion defined in the system, this error will occur.
  
  
  Incorrect UoM Settings: The UoM settings for the material may not be correctly configured in the material master data. This includes the base unit of measure and any alternative units of measure.
  
  
  Material Master Data Issues: The material master may not have the necessary data or may be incomplete, leading to issues during the conversion process.
  
  
  Transaction Context: The error may also arise in specific transactions where UoM conversion is required, such as during goods movements, production orders, or inventory management.
  
  
  Solution:
  
  
  Check UoM Conversion Settings:
  
  Go to the material master (transaction code MM03) and check the UoM settings for the material in question.
  Ensure that the necessary UoM conversions are defined. You can do this in the "Units of Measure" view of the material master.
  
  
  
  Define UoM Conversion:
  
  If the conversion is missing, you can define it using transaction code CUNI (Unit of Measure Conversion). Here, you can create a new conversion entry between the two units of measure.
  
  
  
  Review Material Master Data:
  
  Ensure that the material master data is complete and correctly configured. Check for any missing fields or incorrect entries.
  
  
  
  Check Transaction Context:
  
  Review the specific transaction that triggered the error. Ensure that the UoM being used is appropriate for the transaction and that it aligns with the material's settings.
  
  
  
  Consult Documentation:
  
  If the issue persists, consult SAP documentation or support for further troubleshooting steps specific to your version of SAP.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  MM03: Display Material Master
  CUNI: Maintain Unit of Measure Conversion
  MM02: Change Material Master (if changes are needed)
  
  
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  User Roles and Authorizations: Ensure that the user has the necessary authorizations to make changes to the material master and UoM settings.
  
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
