  The SAP error message USMDA3058 indicates that there is a self-referencing issue with fields in a data model or structure. Specifically, it states that the fields referenced (in this case, &3 and &4) cannot reference themselves, which is not allowed in the context of the data model you are working with.
  Cause:

  Review the Data Model: Check the definitions of the fields &3 and &4 in your data model. Ensure that they are not set to reference each other directly or indirectly.

  Changing the field definitions to eliminate the self-referencing.
  Creating a different structure that allows for the necessary relationships without causing a circular reference.
  
  
  
  Consult Documentation: Refer to SAP documentation or guidelines related to the specific module or data model you are working with. This can provide insights into how to properly structure your fields.
  
  
  Testing: After making changes, test the data model to ensure that the error is resolved and that the model behaves as expected.
