Calling a subscreen from a function module.

Former Member — Sat, 22 Apr 2006 11:55:48 GMT

Hi,

I am implementing a BADI, and in the PUT method of the BADI, I am calling a "Z" function module. In the function module I am doing a call transaction to call a customized screen.

This works fine as long as the attribute of the customized screen is normal, but when I change the attribute of the customized screen to subscreen, it dumps. The dump does not have any info about the reason for the dump.

I want to call a customized screen keeping the screen attribute as subscreen (module pool).

How do I do that? Please help with the syntax.

Thanks in advance.

Mick

Hi,

I guess you have changed the properties of screen only.

I assume you have made a Ztransaction Code.

When you define a transaction code, you need to specify a screen number for radio option program and screen and you need to specify a screen and not subscreen.( I think so!!)

You changed only the code without changing the transaction code properties.

Therefore, i think u r getting a dump.

If you want to call your subscreen, call it in some screen and then call that screen using your transaction code properties.

To include a subscreen screen in the subscreen area of the main screen and call its PBO flow logic, use the following statement in the PBO event of the main screen:

PROCESS BEFORE OUTPUT.

...

CALL SUBSCREEN <area> INCLUDING <prog> <dynp>.

...

To call the PAI flow logic of the subscreen screen, use the following statement in the PAI flow logic of the main screen:

PROCESS AFTER INPUT.

...

CALL SUBSCREEN <area>.

...

Thanks for the reply Tanveer.

One more thing that I would like to add is that, the error message that I am getting

"Screen SAPLZ_CUST_SCREEN 1001 must not be an Include screen"

Also I am displaying the screen in the web and I am seeing the dump in the web.

Thanks,

Mick

Hi,

It will NOT work as the Sub screen has to be placed on a SUB SCREEN element on the main screen where you are going to call the sub screen.

The usual process is you have a MAIN screen and you place the SUB SCREEN control on that. On this SUB SCREEN you call the sub screens dynamically, right. In your case you don't have a main screen, so the dump.

Hi Mick,

As i said earlier.. u need to call the subscreen inside some screen. You are directly calling the subscreen in your transaction code which actually should have been a screen call.

You dont have a screen to display the subscreen and hence you are getting a dump!!

Hi Mick,

sorry but subscreens can only be accessed from the screen flow logic (not native abap) via CALL SUBSCREEN.

Thanks Tanveer/Ravi.

This is what I have done. I have created a screen, No 1002 (main screen), type normal. In this screen I have created a sub screen area. I have also created a screen type subscreen number 111. In the PBO of this main screen, I have written the code

CALL SUBSCREEN SUBSCR111 INCLUDING SY-REPID 111

In the PAI of the main screen I have written the code

CALL SUBSCREEN SUBSCR111

I have also written suitable code for PBO and PAI for subscreen 111.

I have activated all the screens.

Now when I execute, I do not get a dump but I get the error:

"CALL SUBSCREEN: SAPLZSRM_CUST_SCREEN 1002 NO_DYNPRO_NUMBER"

Please help!!!!!

Thanks,

Mick

try putting quotes round the 111:- '111'.... or use a variable which holds the value '111'.

You would need to populate this variable in the PBO.

hi james,

thes3 are the steps to be followed :

1. in the pbo of the main screen, write the stmt :

CALL SUBSCREEN SUBSCR111 INCLUDING SY-REPID num .

2. In the main pgm, decalare a variable num type sy-dynnr.

3. In the PAI of main screen assign num = '111' .

Hi Mick,

one other possibility is that the program involved is not sy-repid. Make sure the call subscreen references the program the subscreen belongs to, i.e. it might not be sy-repid.

Mick,

This is the right way of doing it now, as now you have a MAIN screen and that you have a sub screen, like the way I have explained in my previous post.
