• What is the cause and solution for SAP error message NGC_RAP036 - Characteristic reference to field &1 of table &2 already exists ?

  The SAP error message NGC_RAP036 indicates that there is an attempt to create a characteristic reference to a field in a table that already has an existing reference. This typically occurs in the context of the SAP RAP (Rapid Application Programming) model, where characteristics are defined for entities.
  Cause:
  The error is caused by trying to define a characteristic for a field that has already been defined in the same context. This can happen if:
  
  You are trying to create a new characteristic that references a field that is already being used by another characteristic.
  There is a duplicate definition in your data model or configuration.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Characteristics: Review the existing characteristics in your data model to see if the field you are trying to reference is already defined. You can do this by checking the relevant entity definitions in your RAP model.
  
  
  Modify the Definition: If you find that the field is already referenced, you may need to modify your new characteristic definition. This could involve:
  
  Changing the name of the new characteristic.
  Using a different field that does not conflict with existing definitions.
  
  
  
  Remove Duplicates: If there are duplicate definitions, remove or consolidate them to ensure that each field is only referenced once.
  
  
  Check for Inheritance: If you are working with inherited entities, ensure that the characteristic is not being inherited from a parent entity that already has a reference to the same field.
  
  
  Consult Documentation: Refer to the SAP documentation for RAP and characteristics to ensure that you are following best practices in defining your data model.
  
  
  Testing: After making changes, test the model to ensure that the error is resolved and that the characteristics behave as expected.
