• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK394 - &1 is an 'append' structure; Only 'normal' structures are allowed ?

  The SAP error message CFD_REGISTRY_CHECK394 indicates that there is an issue with the structure being used in a context where only "normal" structures are allowed, while the structure in question is an "append" structure. This typically occurs in the context of data modeling or when working with certain SAP functionalities that do not support append structures.
  Cause:
  
  Append Structure Usage: The error arises because the system is trying to use an append structure in a context that only accepts standard (normal) structures. Append structures are used to add fields to existing database tables or structures, but they cannot be used in all scenarios.
  Data Model Constraints: Certain data models or configurations in SAP may have restrictions on the types of structures that can be used, leading to this error when an append structure is encountered.
  
  Solution:
  
  Use Normal Structures: If possible, replace the append structure with a normal structure that contains the required fields. This may involve creating a new structure that includes all necessary fields without using an append.
  Check Configuration: Review the configuration or data model where the error occurs. Ensure that the structures being used comply with the requirements of the specific SAP functionality or transaction.
  Modify the Data Model: If you have control over the data model, consider modifying it to accommodate the use of normal structures instead of append structures.
  Consult Documentation: Refer to SAP documentation or notes related to the specific transaction or functionality you are working with to understand the limitations regarding structure types.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on how to handle append structures in your scenario.
  Data Dictionary: Familiarize yourself with the SAP Data Dictionary (SE11) to understand the differences between normal and append structures and how they can be used.
  Testing: After making changes, thoroughly test the functionality to ensure that the error is resolved and that the system behaves as expected.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with an SAP expert or reach out to SAP support for further assistance.
