• What is the cause and solution for SAP error message CK656 - Marking has already been allowed ?

  The SAP error message CK656 ("Marking has already been allowed") typically occurs in the context of inventory management and costing in SAP, particularly when dealing with the marking of materials in the context of product costing or inventory valuation.
  Cause:
  This error usually arises when you attempt to mark a material for a specific purpose (like a cost estimate or a valuation) that has already been marked. Marking is a process in SAP that allows you to indicate which stock should be included in a specific valuation or cost estimate. If the material has already been marked, the system will not allow you to mark it again for the same purpose.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Markings: 
  
  Use transaction code CKM3 (Display Material Costing) or CKM2 (Change Material Costing) to check if the material is already marked. Look for any existing markings that may conflict with your current action.
  
  
  
  Unmark the Material: 
  
  If you need to change the marking, you may need to unmark the material first. This can typically be done using transaction code CKM2 or through the appropriate menu path in SAP.
  
  
  
  Review Costing Variants: 
  
  Ensure that you are using the correct costing variant and that it is set up properly. Sometimes, issues can arise from incorrect configurations.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help files related to marking and costing to ensure you are following the correct procedures.
  
  
  
  Check User Authorizations: 
  
  Ensure that you have the necessary authorizations to perform marking and unmarking actions in the system.
  
  
  
  Contact SAP Support: 
  
  If the issue persists and you cannot find a resolution, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or patches related to this error.
