• What is the cause and solution for SAP error message FDT_CP_MSG108 - Nested structure is not supported ?

  The SAP error message FDT_CP_MSG108: Nested structure is not supported typically occurs in the context of using the SAP Form Data Tool (FDT) or when working with forms and data structures in SAP. This error indicates that the system encountered a nested structure that it does not support.
  Cause:
  
  Nested Structures: The error arises when a data structure (like a table or a form) contains another structure within it. SAP FDT may not support this kind of nesting, leading to the error.
  Data Model Limitations: The data model being used may have limitations regarding the depth of nested structures, which can lead to this error when trying to process or render the data.
  Configuration Issues: There may be issues with how the data structures are configured in the FDT or the underlying data model.
  
  Solution:
  
  Flatten the Structure: Review the data structure and try to flatten it by removing nested elements. Instead of having a nested structure, consider using a flat structure or separate tables that can be linked.
  Modify the Data Model: If possible, adjust the data model to avoid nesting. This may involve redesigning how data is organized and accessed.
  Check FDT Configuration: Ensure that the configuration in the FDT is correct and that it aligns with the data structures being used. Look for any settings that might allow for handling nested structures.
  Consult Documentation: Refer to the SAP documentation for FDT to understand the limitations and best practices regarding data structures.
  SAP Notes and Support: Check for any relevant SAP Notes that might address this issue or provide patches or updates that could resolve the problem. If necessary, contact SAP support for assistance.
