• What is the cause and solution for SAP error message C1049 - End of screen sequence ?

  The SAP error message C1049, "End of screen sequence," typically occurs when there is an issue with the screen flow in a transaction or program. This error indicates that the system has reached the end of a screen sequence unexpectedly, which can happen for several reasons.
  Causes:
  
  Screen Sequence Configuration: The screen sequence defined in the program may not be correctly configured, leading to an unexpected end.
  Program Logic Errors: There may be logical errors in the ABAP code that control the screen flow, causing the program to skip screens or terminate prematurely.
  Missing Screens: If a screen that is supposed to be displayed is missing or not properly defined in the program, it can lead to this error.
  User Exits or Enhancements: Custom user exits or enhancements may interfere with the normal screen flow, causing the program to end unexpectedly.
  Authorization Issues: Sometimes, if a user does not have the necessary authorizations to access a particular screen, it may lead to an abrupt end of the screen sequence.
  
  Solutions:
  
  Check Screen Sequence: Review the screen sequence in the transaction or program to ensure that it is correctly defined and that all necessary screens are included.
  Debugging: Use the ABAP debugger to step through the program and identify where the screen flow is breaking. Look for any logical errors or conditions that may cause the program to skip screens.
  Review Custom Code: If there are any custom enhancements or user exits, review them to ensure they are not causing the issue. Temporarily disable them to see if the error persists.
  Check Authorizations: Ensure that the user has the necessary authorizations to access all screens in the transaction. You can check this using transaction SU53 after the error occurs.
  Consult SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address this specific error or provide patches or updates that resolve the issue.
