• What is the cause and solution for SAP error message CI_DRAFTPRD_MESSAGE109 - Enter a valid lot size (products planning) ?

  The SAP error message CI_DRAFTPRD_MESSAGE109, which states "Enter a valid lot size," typically occurs in the context of product planning, particularly when dealing with production orders, material requirements planning (MRP), or similar processes. This error indicates that the lot size entered for a production order or planning scenario is not valid according to the system's configuration or the specific parameters set for the material.
  Causes:
  
  Invalid Lot Size Configuration: The lot size defined in the material master or the production order may not conform to the allowed lot sizes configured in the system.
  Missing Lot Size in Material Master: The material master record may not have a defined lot size or may have an incorrect lot size category.
  Incorrect Planning Parameters: The planning parameters set for the material may not align with the lot size requirements.
  User Input Error: The user may have entered a lot size that is not permissible, such as a negative number, zero, or a non-integer value.
  Lot Size Ranges: The lot size may fall outside the defined ranges for the specific production process or material.
  
  Solutions:
  
  
  Check Material Master Data:
  
  Go to the material master (transaction code MM03) and verify the lot size settings under the relevant views (e.g., MRP view).
  Ensure that the lot size category (e.g., fixed lot size, lot-for-lot) is correctly defined.
  
  
  
  Review Production Order Settings:
  
  If the error occurs during the creation of a production order, check the order's lot size field to ensure it is filled with a valid value.

  Adjust Planning Parameters:
  
  Review the planning parameters in the MRP settings (transaction code MD02 or MD03) to ensure they are correctly set for the material.
