Screen flow issue

VenuAnumayam — Mon, 16 Nov 2009 21:01:12 GMT

Hello Experts,

I have designed my first module pool programming application. On the first screen (Screen# 9000) when the users click on a button, it will show a pop-up(Screen# 0100). When the users click on "Cancel" button on the pop-up, it should go back to the first screen (Screen#9000) - which is working fine. However, when the users click on the "Green Arrow/F3/BACK" button, it is showing the pop-up screen again instead of getting out of the screen.

Can you please let me know what went wrong.

Thanks.

Here's the flow-logic for screens:

Screen#9000

Clear ok code if there is any or clear Sy-ucomm if you are using sy-ucomm in PAI user_command module

Sorry. I have modified the Subject now and reformatted the content of the post.

I have also debugged the code and found that the program processes the flow logic of 0100 again when it should come out.

Thanks.

The code for screen# 9000.

PROCESS BEFORE OUTPUT. 
MODULE STATUS_9000. 

PROCESS AFTER INPUT.
