• What is the cause and solution for SAP error message KJ245 - The costing lot size is zero. Check the cost estimate ?

  The SAP error message KJ245, which states "The costing lot size is zero. Check the cost estimate," typically occurs during the cost estimation process in SAP, particularly when dealing with product costing in the Controlling (CO) module. This error indicates that the system has encountered a situation where the costing lot size for a material or product is set to zero, which is not valid for cost estimation purposes.
  Cause:
  
  Costing Lot Size Configuration: The costing lot size is defined in the material master or in the cost estimate itself. If it is set to zero, the system cannot calculate costs because it does not have a valid quantity to work with.
  Missing Data: The material master record may be incomplete or incorrectly configured, leading to a zero costing lot size.
  Costing Variant Settings: The costing variant used for the cost estimate may not be configured correctly, leading to issues with the costing lot size.
  Costing Run Issues: If the costing run was not executed properly or if there were issues during the costing run, it could lead to this error.
  
  Solution:
  
  
  Check Material Master: 
  
  Go to the material master record (transaction code MM03) and check the costing view. Ensure that the costing lot size is set to a valid value greater than zero.
  If necessary, update the costing lot size in the material master.
  
  
  
  Review Cost Estimate:
  
  Check the cost estimate (transaction code CK11N or CK40N) to ensure that the costing lot size is correctly defined.
  If you are using a specific costing variant, ensure that it is set up correctly and that it references the correct costing lot size.
  
  
  
  Adjust Costing Variant:
  
  Review the settings of the costing variant (transaction code OKKN) to ensure that it is configured to use the correct costing lot size.
  
  
  
  Re-run Costing:
  
  After making the necessary adjustments, re-run the cost estimate to see if the error persists.
