• What is the cause and solution for SAP error message 37786 - Group can only contain radio buttons ?

  The SAP error message "37786: Group can only contain radio buttons" typically occurs in the context of SAP GUI programming, particularly when dealing with screen elements in a dialog program or a module pool. This error indicates that a group of radio buttons has been defined incorrectly, where the system expects only radio buttons to be part of that group.
  Cause:
  
  Mixed Control Types: The error arises when a group of radio buttons (defined in a screen) contains other types of controls (like checkboxes, input fields, etc.) along with radio buttons. In SAP, a radio button group must exclusively contain radio buttons.
  Incorrect Grouping: The radio buttons may not be properly grouped using the same group name, or there may be an attempt to group controls that are not compatible.
  
  Solution:
  
  Check Control Types: Ensure that all controls within the group are radio buttons. Remove any non-radio button controls from the group.
  Correct Grouping: Make sure that all radio buttons that are intended to be part of the same group share the same group name. This is done in the screen painter or in the screen attributes.
  Review Screen Layout: Open the screen in the Screen Painter and verify the properties of the radio buttons. Ensure that they are correctly set up as part of a radio button group.
  Recreate the Group: If necessary, delete the existing radio buttons and recreate them, ensuring they are grouped correctly from the start.
  
  Related Information:
  
  Radio Button Grouping: In SAP, radio buttons are used for mutually exclusive options. Only one radio button in a group can be selected at a time.
  Screen Painter: This is the tool used to design screens in SAP. Familiarity with the Screen Painter is essential for managing screen elements effectively.
  SAP Documentation: For more detailed information, refer to the SAP Help Portal or the specific documentation related to the version of SAP you are using.
