• What is the cause and solution for SAP error message CK340 - Costing lot size changed from & & to & & ?

  The SAP error message CK340 indicates that the costing lot size for a material has changed, which can affect the cost calculation for that material. This message typically arises during the costing process when the system detects a discrepancy between the expected lot size and the actual lot size defined in the material master or in the costing variant.
  Cause:
  
  Change in Lot Size: The most common cause is that the lot size defined in the material master or in the costing variant has been changed. This could happen due to updates in production planning, changes in the material master data, or adjustments in the costing variant settings.
  Costing Variant Settings: The costing variant may have been modified to use a different lot size than what was previously set.
  Material Master Data Changes: Changes in the material master data, such as the base quantity or unit of measure, can lead to this error.
  Costing Run: If a costing run is executed after changes have been made to the lot size, the system may flag this error.

  Review Material Master Data: Check the material master data for the affected material to ensure that the lot size is set correctly. You can do this by navigating to the material master (transaction code MM03) and reviewing the relevant views (e.g., Basic Data, Purchasing, and Accounting).

  Adjust Lot Size: If the lot size has been changed intentionally, ensure that all relevant settings and data are updated accordingly. If the change was not intended, revert the lot size to its previous value.
  Re-run Costing: After making the necessary adjustments, re-run the costing process to see if the error persists.
