  The SAP error message FDT_CORE391 indicates an issue with recursion in the context of field definitions or data types in the SAP system. Specifically, the message states that an object (like a field or a data type) is referencing itself indirectly through another object, which creates a circular reference. This can lead to problems in processing or interpreting the data structure.
  
  Cause:
  The error occurs when:
  
  A field or data type (denoted as &1) is defined in such a way that it references another field or data type (denoted as &2), which in turn references the original field or data type (&1). This creates a loop or recursion that the system cannot resolve.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Fields/Data Types: Review the definitions of the fields or data types involved in the error message. Check the relationships and dependencies between them.
