GET/SET Parameters not working

former_member271795 — Tue, 03 Apr 2012 09:08:49 GMT

I have a problem in setting and receiving parameter id's

What I want to do is SET a value in a module in the PBO of a screen then get the value to be used in a search help function

What I'm getting is a return code 4 when trying to do the GET

The code I'm using is

**** set parameter in the screen module

MODULE ZSETPARMS OUTPUT..
data l_SUB type subty.
move P0102-SUBTY to l_sub.

SET PARAMETER ID 'ZSUB' Field l_sub

*****The get statement in the search help

IF CALLCONTROL-STEP = 'PRESEL1'.

data l_sub type subty.

data l_selopt type DDSHSELOPT.

get parameter id 'ZSUB' field L_SUB..

The <pid> is registered in TPARA

Could anyone tell me where I'm going wrong

thanks

Hi,

Is your parameter created in table TPARA?

Manu.

added: It seems it is, I didn't read your post completely...;) I cannot see anything wrong with your syntax, another alternative would be to use an export/import statement...

Declare variable I_sub and L_sub in top include and try.

Hello Geoff,

If i understand the requirement correctly, you want to populate you F4 help values based on some other input in the screen.

When the user inputs the value & presses the F4 help the POV module is triggered & not the PBO, hence the GPA is returning SY-SUBRC = 4!

You need to use DYNP_VALUES_READ to read the data from the screen. Refer to the demo program DEMO_DYNPRO_F4_HELP_MODULE.

BR,

Suhas

PS: After inputting the data in the screen, press 'Enter' & then check if the GPA statement works

Hi Geoff,

From where you are calling search help function?

If from PAI then it won't work.

Try to set your parameter in PAI module and then use that parameter ID in your search help function, you will definitely get ....

I have used many time, even if you don't register your parameter ID in TPARA table then also you will get parameter ID data.

Try to debug your code and check whether your Search help FM is being call after executing SET PARAMETER ID 'ZSUB' Field l_sub or not.. Try something like that.

All the best.
