• What is the cause and solution for SAP error message 37182 - Only checkboxes, radio buttons and pushbuttons allowed in loop lines ?

  The SAP error message 37182 ("Only checkboxes, radio buttons and pushbuttons allowed in loop lines") typically occurs in the context of SAP GUI programming, particularly when dealing with screen elements in a dialog program. This error indicates that there is an issue with the type of UI elements being used in a loop line of a screen.
  Cause:
  The error arises when you attempt to use UI elements that are not allowed in a loop line. In SAP GUI programming, only certain types of elements (checkboxes, radio buttons, and pushbuttons) are permitted in loop lines. If you try to include other types of elements (like text fields, input fields, etc.) in a loop line, the system will throw this error.
  Solution:
  To resolve this error, you should:
  
  
  Review the Screen Layout: Check the screen layout in the screen painter (SE80 or SE41) to ensure that only the allowed UI elements (checkboxes, radio buttons, and pushbuttons) are included in the loop line.
  
  
  Modify the Code: If you are dynamically creating UI elements in your ABAP code, ensure that you are only creating the allowed types of elements within the loop. Replace any disallowed elements with the appropriate ones.
  
  
  Check the Loop Definition: Ensure that the loop is defined correctly and that it is intended to contain only the allowed UI elements.
  
  
  Testing: After making the necessary changes, test the screen to ensure that the error no longer occurs and that the UI behaves as expected.

  SAP GUI Programming: Familiarize yourself with the guidelines for creating screens and UI elements in SAP. The SAP documentation provides detailed information on the types of elements that can be used in different contexts.
