• What is the cause and solution for SAP error message FDT_CORE392 - Invalid recursion: &1 uses &2 uses &3 uses &1 ?

  The SAP error message FDT_CORE392 indicates an issue with recursion in the context of field definitions or data types in the SAP system. Specifically, the message states that there is an invalid recursion where a field or data type is referencing itself indirectly through a chain of other fields or data types. The placeholders &1, &2, and &3 represent the specific field or data type names involved in the recursion.
  Cause:
  The error typically arises from:
  
  Circular References: A field or data type is defined in such a way that it references itself, either directly or indirectly through other fields or data types.
  Incorrect Field Definitions: The definitions of fields or data types may not be set up correctly, leading to unintended recursive relationships.
  Modeling Errors: When creating or modifying data models, it is possible to inadvertently create a loop in the references.
  
  Solution:
  To resolve the FDT_CORE392 error, you can take the following steps:
  
  
  Review Field Definitions: Check the definitions of the fields or data types mentioned in the error message. Look for any direct or indirect references that may lead to recursion.
  
  
  Identify Circular References: Trace the references between the fields or data types to identify where the circular reference occurs. You may need to analyze the relationships in detail.
  
  
  Modify Definitions: Once you identify the circular reference, modify the field or data type definitions to eliminate the recursion. This may involve changing the way fields reference each other or restructuring the data model.
  
  
  Test Changes: After making changes, test the affected functionality to ensure that the error is resolved and that the system behaves as expected.
  
  
  Consult Documentation: If you are unsure about how to modify the definitions, refer to SAP documentation or seek guidance from a colleague or SAP consultant with experience in data modeling.
