• What is the cause and solution for SAP error message GMMASTERDATA174 - IDC rule exists but no classes are marked as relevant for indirect costs ?

  The SAP error message GMMASTERDATA174 indicates that there is an issue with the configuration of the Indirect Cost (IDC) rules in the SAP system. Specifically, it means that while an IDC rule exists, there are no classes marked as relevant for indirect costs. This can prevent the proper allocation of indirect costs in your project or cost center accounting.
  Cause:
  
  Missing Configuration: The IDC rule has been defined, but the relevant classes (such as cost elements or cost centers) have not been marked as relevant for indirect costs.
  Incorrect Assignment: The classes that should be associated with the IDC rule may not have been properly assigned or configured in the system.
  Data Entry Error: There may be a data entry error where the relevant classes were not selected or saved correctly.
  
  Solution:
  To resolve the GMMASTERDATA174 error, follow these steps:
  
  
  Check IDC Rule Configuration:

  Verify that the IDC rule in question is correctly set up.
  
  
  
  Mark Classes as Relevant:
  
  Identify the classes (cost elements, cost centers, etc.) that should be relevant for indirect costs.
  Ensure that these classes are marked as relevant for the IDC rule. This can typically be done in the configuration settings for the IDC rules.
  
  
  
  Review Class Assignments:
  
  Check the assignments of the classes to ensure they are correctly linked to the IDC rule.
  If necessary, reassign or update the classes to ensure they are included in the IDC calculations.
  
  
  
  Test the Configuration:
  
  After making the necessary changes, test the configuration by running a simulation or processing a transaction that utilizes the IDC rule to ensure that the error no longer occurs.
