• What is the cause and solution for SAP error message CK717 - Unit of measure & could not be converted to unit of measure & ?

  The SAP error message CK717 typically indicates that there is an issue with the conversion of units of measure (UoM) in the context of material valuation or cost calculation. This error can occur in various transactions, particularly in the Material Ledger or during the costing process.
  Cause:
  
  
  Missing Conversion Factors: The system may not have the necessary conversion factors defined for the units of measure involved. For example, if you are trying to convert from kilograms to grams, the conversion factor must be defined in the system.
  
  
  Incorrect UoM Configuration: The units of measure may not be properly configured in the material master or in the relevant settings. This can include issues with the base unit of measure or alternative units of measure.
  
  
  Inconsistent UoM Usage: The error can occur if there is an inconsistency in how units of measure are used across different documents or transactions. For example, if a material is defined with one UoM in the material master but is being processed with another UoM in a transaction.
  
  
  Missing UoM in Master Data: The unit of measure being used may not be defined in the system at all, leading to conversion issues.
  
  
  Solution:
  
  
  Check Material Master Data: Go to the material master (transaction MM03) and check the units of measure defined for the material. Ensure that the base unit of measure and any alternative units of measure are correctly set up.
  
  
  Define Conversion Factors: If conversion factors are missing, you can define them in the material master under the "Units of Measure" view. Ensure that the conversion factors between the units of measure are correctly specified.
  
  
  Review UoM Configuration: Check the configuration settings for units of measure in the SAP system (transaction OME4). Ensure that the units of measure are correctly defined and that the conversion factors are in place.
  
  
  Consistency Check: Ensure that all documents related to the material (such as purchase orders, production orders, etc.) are using the correct and consistent units of measure.
  
  
  Consult SAP Notes: If the issue persists, check for any relevant SAP Notes that may address this specific error. SAP Notes can provide patches or additional guidance on resolving specific issues.
  
  
  Testing: After making changes, perform a test transaction to ensure that the error no longer occurs.
