• What is the cause and solution for SAP error message FDT_CHANGE_INFO526 - Interface of procedure call expression was changed from &1 to &2 ?

  The SAP error message FDT_CHANGE_INFO526 indicates that there has been a change in the interface of a procedure call expression in your SAP system. This typically occurs when the signature of a function module, method, or any callable procedure has been modified, which can lead to inconsistencies in the way the procedure is called in your code.
  Cause:
  
  Change in Function Module/Method Signature: The most common cause is that the parameters of a function module or method have been changed (e.g., added, removed, or modified).
  Transport Requests: If changes were made in a development environment and transported to a production environment, the interfaces may not match if the transport was not executed correctly or if there were subsequent changes.
  Versioning Issues: If different versions of the same function module or method are being referenced in different parts of the code, this can lead to discrepancies.
  
  Solution:
  
  Review Changes: Check the change logs for the function module or method that is causing the error. Identify what changes were made to the interface.
  Update Calls: Update the calls to the function module or method in your code to match the new interface. This may involve adding or removing parameters or changing their types.
  Consistency Check: Ensure that all parts of your code that call the modified procedure are updated consistently.
  Transport Management: If the issue arose due to transport requests, ensure that all relevant transports are correctly applied and that the environments are synchronized.
  Testing: After making the necessary changes, thoroughly test the affected areas of your application to ensure that everything functions as expected.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific function module or method you are working with.
  Documentation: Review the documentation for the function module or method to understand the expected parameters and their types.
