• What is the cause and solution for SAP error message E2242 - 'Key' column is visible ?

  The SAP error message E2242, which states "'Key' column is visible," typically occurs in the context of SAP applications when there is an issue related to the visibility of key fields in a table or data structure. This error can arise in various scenarios, such as when working with data entry screens, reports, or custom developments.
  Cause:
  The error usually indicates that a key column (or field) that is supposed to be hidden or not visible to the user is currently displayed on the screen. This can happen due to:
  
  Configuration Issues: The screen or report configuration may not be set up correctly, leading to key fields being displayed when they should not be.
  Custom Development: If there are custom programs or enhancements, the logic may inadvertently make key fields visible.
  User Authorizations: Sometimes, user roles and authorizations may not be set up correctly, allowing access to fields that should be restricted.
  
  Solution:
  To resolve the E2242 error, you can take the following steps:
  
  
  Check Screen Configuration:
  
  If you are using a standard SAP transaction, check the configuration settings for the screen. Ensure that the key fields are set to be hidden if they should not be visible.
  If you are using a custom screen, review the screen layout in the Screen Painter or the relevant development environment.
  
  
  
  Review Custom Code:
  
  If there is custom code involved, review the logic to ensure that key fields are not being made visible unintentionally. Look for any statements that might be setting the visibility of fields.
  
  
  
  User Authorizations:
  
  Check the user roles and authorizations to ensure that users do not have access to fields that should be restricted. Adjust the authorizations as necessary.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific transaction or module you are working with. There may be known issues or additional configuration steps required.
  
  
  
  Testing:
  
  After making changes, test the transaction or report to ensure that the error is resolved and that the key fields are no longer visible.
