• What is the cause and solution for SAP error message /CWM/LES123 - Default quantity calculated using plan conversion factor of material ?

  The SAP error message /CWM/LES123 Default quantity calculated using plan conversion factor of material typically occurs in the context of warehouse management or logistics execution when there is an issue with the conversion factors used for materials in the system. This message indicates that the system is using a default quantity based on the plan conversion factor for a material, which may not be the intended behavior.
  Cause:
  
  
  Missing or Incorrect Conversion Factors: The error often arises when the conversion factors for a material are not properly defined in the system. This can happen if the material master data is incomplete or if the conversion factors have not been maintained correctly.
  
  
  Material Master Data Issues: If the material master does not have the necessary data for the specific unit of measure or if the data is inconsistent, the system defaults to using a standard conversion factor.
  
  
  Configuration Issues: There may be configuration settings in the system that are not aligned with the business processes, leading to the system defaulting to a plan conversion factor.
  
  
  Solution:
  
  
  Check Material Master Data: 
  
  Go to the material master record (transaction code MM03) and verify that the conversion factors are correctly maintained for the relevant units of measure.
  Ensure that the base unit of measure and any alternative units of measure are correctly defined.
  
  
  
  Maintain Conversion Factors:
  
  If the conversion factors are missing, you can maintain them in the material master under the "Purchasing" or "Sales" views, depending on the context of the error.
  Use transaction code MM02 to update the material master data.
  
  
  
  Review Configuration Settings:
  
  Check the configuration settings in the Logistics Execution module to ensure that they are set up correctly. This may involve reviewing the settings for unit of measure conversions in the IMG (Implementation Guide).
  Ensure that the relevant settings for warehouse management and logistics execution are aligned with your business processes.
  
  
  
  Testing: After making the necessary changes, perform a test transaction to ensure that the error no longer occurs and that the system calculates the quantities as expected.
