How to fix this error?

Before saving/generating, check that the assumptions made by the system
correspond to your wishes. To do this, look at the element list or
select the <LS>Attributes</> function for the critical fields. If you
do not agree, leave screen editing without saving or generating. Then,
restart the editing process and divide your complex changes on one line
into several smaller changes.

• What is the cause and solution for SAP error message 37204 - Non-executable element changes in a dynpro line ?

  The SAP error message 37204 ("Non-executable element changes in a dynpro line") typically occurs in the context of screen programming (dynpro) in ABAP when there are changes made to a screen element that cannot be executed or processed as expected. This error is often related to the way screen elements are defined or manipulated in the ABAP code.
  Cause:
  
  Non-Executable Changes: The error usually arises when there are attempts to change properties of screen elements (like input fields, buttons, etc.) in a way that is not allowed. For example, trying to change the attributes of a screen element that is not in a modifiable state.
  Screen Flow Logic: The error can also occur if there are inconsistencies in the screen flow logic, such as trying to modify a screen element after it has already been processed or displayed.
  Incorrect Screen Attributes: If the screen attributes are not set correctly (e.g., a field is set to display-only but is being modified), this can lead to the error.
  
  Solution:
  
  Check Screen Element Properties: Review the properties of the screen elements in the screen painter (SE80 or SE41). Ensure that the elements you are trying to modify are set to be modifiable if you intend to change them.
  Review ABAP Code: Look at the ABAP code that is manipulating the screen elements. Ensure that changes to the screen elements are made at the appropriate time in the screen flow (e.g., before the screen is displayed).
  Use Correct Statements: Make sure you are using the correct ABAP statements to modify screen elements. For example, use SET SCREEN or CALL SCREEN appropriately to control the flow.
  Debugging: Use the debugger to step through the code and identify where the error occurs. This can help pinpoint the exact line of code that is causing the issue.
  Check for Dynamic Changes: If you are dynamically changing screen elements, ensure that the logic is sound and that you are not trying to change elements that are not currently active or visible.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE80 (Object Navigator) or SE41 (Menu Painter) to check and modify screen elements.
  Documentation: Refer to the SAP Help Portal or ABAP documentation for more details on screen programming and handling screen elements.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to this error message.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
