• What is the cause and solution for SAP error message GD126 - The gen. calc. parameters are only allowed if costing is required. ?

  The SAP error message GD126 ("The gen. calc. parameters are only allowed if costing is required") typically occurs in the context of material master data or when working with cost estimates in SAP. This error indicates that general calculation parameters have been set, but the system does not require costing for the specific transaction or material.
  Cause:
  
  Costing Not Required: The error arises when the system detects that costing is not required for the material or the transaction you are trying to process, yet general calculation parameters have been defined.
  Configuration Issues: There may be configuration settings in the material master or in the controlling area that do not align with the requirements for costing.
  Incorrect Settings: The settings in the material master or the cost estimate may not be correctly configured to allow for general calculation parameters.
  
  Solution:
  
  
  Check Material Master Settings:
  
  Go to the material master record (transaction code MM03) and check the relevant views (especially the Accounting and Costing views).
  Ensure that the costing type is set correctly and that costing is indeed required for the material.
  
  
  
  Review Costing Configuration:
  
  Check the configuration settings in the controlling area (transaction code OKKP) to ensure that costing is enabled for the relevant materials or processes.
  Verify that the costing variant and other related settings are correctly configured.
  
  
  
  Adjust General Calculation Parameters:
  
  If costing is not required for the material or transaction, consider removing or adjusting the general calculation parameters that are causing the error.
  If costing is required, ensure that all necessary parameters are correctly set up.
  
  
  
  Consult Documentation:
