• What is the cause and solution for SAP error message WY066 - Possible entries cannot be displayed in display mode ?

  SAP Error Message:
  
  WY066 - Possible entries cannot be displayed in display mode
  
  Cause:
  This error typically occurs when a user tries to display possible entries (F4 help) for a field in display mode (i.e., when the screen or transaction is in display-only mode). In display mode, the system restricts certain interactive functions such as showing possible entries or value help because the data is not editable.
  In other words, the system prevents the F4 help from being triggered when the screen is set to display mode, as no changes or selections are expected to be made.
  
  Explanation:
  
  Display mode means the user can only view data, not modify it.
  Possible entries (F4 help) require the ability to select or input data, which is not allowed in display mode.
  Hence, SAP throws the message WY066 to indicate that possible entries cannot be shown.
  
  
  Solution:
  
  
  Switch to Change Mode:
  
  If you need to use the F4 help to select or change data, switch the transaction or screen from display mode to change mode (if allowed). This enables the system to show possible entries.
  
  
  Check User Authorization:
  
  Sometimes, users are restricted to display mode due to authorization profiles. Verify if the user has the necessary authorization to change data.
  
  
  Programmatic Handling (for developers):
  
  If you are developing or customizing a screen or module pool, ensure that the F4 help is not triggered in display mode. You can add a check in the code to suppress the F4 help or provide an appropriate message.
  
  
  Use Search Helps Appropriately:
  
  If the field is only for display, consider removing or disabling the F4 help for that field in display mode.
  
  
  
  Related Information:
  
  Transaction Codes: This message can appear in various SAP transactions where display mode is enforced.

  User Roles: Check roles and authorizations if users report this message unexpectedly.
  Debugging: Developers can debug the screen flow logic to see why the system is in display mode and why F4 help is triggered.
