Check if screen exist

Former Member — Thu, 22 Feb 2007 10:18:00 GMT

Hi,

I've made a kind of screen exist in my application. It calls a screen from an other report, but no I want to include a check if the screen exists in that report and if the screen is of the type subscreen. Any ideas on how to do this?

Hi Bjorn,

Use the statement CALL SUBSCREEN...

Check the value of sy-subrc immediately after this statement.

If the value is non zero, then the subscreen does not exist.

Hi Ravi,

Thank you for your answer.

However I don't think this is possible for different reasons:

1. I don't want to call my subscreen yet

2. I'm using selection-screen tabbed block as subscreen area so I'm not going into PBO or PAI modules and there's the only place to call subscreens I think

I've managed to solve this issue using the function RS_SCREEN_LIST. This function takes as arguments a program name and a screen number. It returns a table with properties of the screen. If the column 'TYPE' of this table equals 'I', then it's a subscreen. It also has an exception 'Screen does'nt exist'.
