• What is the cause and solution for SAP error message FDT_CORE407 - Code type GDT contains another structure code ?

  The SAP error message FDT_CORE407 indicates that there is an issue with the configuration of a Global Data Type (GDT) in the context of the SAP Fiori Data Transformation (FDT) framework. Specifically, the error message states that the code type GDT contains another structure code, which is not allowed.
  Cause:
  The error typically arises when:
  
  A Global Data Type (GDT) is defined in such a way that it includes another structure or GDT, which is not permitted.
  There may be a misconfiguration in the data model where a GDT is incorrectly referencing another structure instead of using simple data types or primitive types.
  
  Solution:
  To resolve the FDT_CORE407 error, you can follow these steps:
  
  
  Review the GDT Definition:
  
  Go to the transaction code SE11 (Data Dictionary) and check the definition of the GDT that is causing the error.
  Ensure that the GDT does not include another structure or GDT. It should only consist of primitive data types (like CHAR, NUMC, etc.).
  
  
  
  Modify the GDT:
  
  If the GDT is incorrectly defined, modify it to remove any nested structures. You may need to create separate GDTs for the nested structures if necessary.
  
  
  
  Check Dependencies:
  
  Ensure that there are no dependencies or references to other GDTs or structures that could be causing the issue.
  
  
  
  Test the Changes:
  
  After making the necessary changes, test the GDT in the context where the error was occurring to ensure that the issue is resolved.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct structure of GDTs, refer to the SAP documentation or guidelines on defining Global Data Types in the FDT framework.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after making the changes, consider reaching out to SAP support for further assistance.
