How To Fix KQ445 - More than one costing variant with same costing type/val. vrnt exists

SAP Error Message - Details

• Message type: E = Error

• Message class: KQ - Error Messages for Customizing Product Costing

• Message number: 445

• Message text: More than one costing variant with same costing type/val. vrnt exists

What causes this issue?

The combination of costing type and valuation variant used in this
costing variant is also used in at least one other costing variant
(such as &V1&).
Although it is technically possible to have two costing variants with
the same combination of costing type and valuation variant, this should
be avoided to prevent data from being overwritten.
When cost estimates are saved, the system uses the costing type and the
valuation variant as the key, rather than the costing variant. It is
therefore possible that a cost estimate with a given costing type and
valuation variant will overwrite another cost estimate that has the
same costing type and valuation variant, even though the costing
variants are different.

• What is the cause and solution for SAP error message KQ445 - More than one costing variant with same costing type/val. vrnt exists ?

  The SAP error message KQ445 indicates that there is a conflict in the configuration of costing variants within the system. Specifically, it means that there are multiple costing variants defined for the same costing type and valuation variant, which is not allowed in SAP.
  Cause:
  The error typically arises from one of the following situations:
  
  Duplicate Configuration: There are multiple costing variants configured in the system that share the same costing type and valuation variant.
  Incorrect Customization: During the setup of costing variants, the same combination of costing type and valuation variant may have been inadvertently assigned to different costing variants.
  Transport Issues: If configurations were transported from one system to another (e.g., from development to production), it might have led to duplicates if the same configurations were already present in the target system.
  
  Solution:
  To resolve the KQ445 error, you can follow these steps:
  
  
  Check Costing Variants:
  
  Go to the transaction code OKKN (Costing Variants) in SAP.
  Review the list of costing variants and identify any duplicates that have the same costing type and valuation variant.
  
  
  
  Remove or Modify Duplicates:
  
  If you find duplicates, you can either delete the unnecessary costing variant or modify it to ensure that each costing type and valuation variant combination is unique.
  
  
  
  Adjust Customization:
  
  If the duplicates were created due to incorrect customization, ensure that the configuration is corrected to prevent future occurrences.
  
  
  
  Transport Management:
  
  If the issue arose from a transport, check the transport logs and ensure that the configurations are consistent across systems. You may need to adjust the configurations in the target system to align with the source.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis or functional team for best practices on managing costing variants.
  
  
  
  Related Information:
  
  Costing Type: This defines how costs are calculated in the system (e.g., standard costing, actual costing).
  Valuation Variant: This determines how the valuation of materials is carried out in the system.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  OKKN: Costing Variants
  CK11N: Create Material Cost Estimate
  CK40N: Execute Costing Run
  
  
  
  By following these steps, you should be able to resolve the KQ445 error and ensure that your costing variants are correctly configured in SAP.
