• What is the cause and solution for SAP error message 37185 - Select only one dynpro element ?

  The SAP error message 37185, "Select only one dynpro element," typically occurs in the context of screen programming (dynpro) in SAP ABAP. This error indicates that the user has attempted to select multiple elements (like input fields, radio buttons, etc.) on a screen when only one selection is allowed.
  Cause:
  
  Multiple Selections: The user has selected more than one dynpro element when the logic of the program expects only one to be selected.
  Incorrect Screen Logic: The screen design or the associated ABAP code may not be correctly handling the selection logic, leading to this error.
  User Interface Design: The design of the screen may not clearly indicate that only one selection is allowed, leading to user confusion.
  
  Solution:
  
  Review Screen Design: Check the screen layout in the Screen Painter (SE80 or SE41) to ensure that the elements are designed correctly. If only one selection is allowed, consider using radio buttons or a dropdown list instead of checkboxes.
  Modify ABAP Code: If the error is triggered by the ABAP code, review the logic that processes the user input. Ensure that the code checks for multiple selections and handles them appropriately.
  User Instructions: Provide clear instructions on the screen to inform users that only one selection is allowed. This can help reduce user errors.
  Debugging: If the issue persists, use the debugger to trace the program execution and identify where the multiple selections are being processed incorrectly.
  
  Related Information:
  
  Dynpro Elements: Understand the different types of dynpro elements (input fields, radio buttons, checkboxes, etc.) and their intended use cases.
  Screen Programming: Familiarize yourself with screen programming concepts in ABAP, including how to handle user input and validate selections.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message, as there may be specific fixes or recommendations provided by SAP.
