SAP Error Message - Details

• Message type: E = Error

• Message class: KO - Master data for CO orders

• Message number: 356

• Message text: Caution: all production versions are being costed again

What causes this issue?

The production cost collector you are processing at present collects
costs at material level - that is, for all the product versions in a
material.
Therefore, costing for the version confirmation data for repetitive
manufacturing is carried out for all production versions assigned to
the material. This can be very time consuming. Please wait.

• What is the cause and solution for SAP error message KO356 - Caution: all production versions are being costed again ?

  The SAP error message KO356, which states "Caution: all production versions are being costed again," typically occurs in the context of cost accounting and production planning within the SAP system. This message indicates that the system is recalculating the costs for all production versions of a material, which can be a resource-intensive process.
  Cause:
  
  Costing Run Triggered: The error is usually triggered when a costing run is initiated for a material that has multiple production versions. This can happen during a standard costing run or when a user manually triggers a cost estimate.
  Changes in Master Data: If there have been changes in the master data (like BOM, routing, or material master) that affect the cost calculation, the system may need to re-cost all production versions.
  Costing Variant Settings: The settings in the costing variant may also lead to this message if they are configured to recalculate costs for all versions.
  
  Solution:
  
  Review Production Versions: Check the production versions of the material in question. Ensure that they are correctly set up and that any changes made to the BOM or routing are necessary.
  Costing Run Settings: Review the settings in the costing variant to determine if it is necessary to recalculate all production versions. If not, you may want to adjust the settings to limit the scope of the costing run.
  Execute Costing in Background: If the recalculation is necessary, consider executing the costing run in the background to avoid performance issues during peak hours.
  Monitor System Performance: If this message appears frequently, monitor the system performance and consider optimizing the costing process or scheduling it during off-peak hours.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific guidance related to your system configuration and business processes.
