Module Pool Input/Output Field Issue

Former Member — Thu, 08 Aug 2013 04:41:10 GMT

Dear All,

I have a custom Module Pool screen wherein i have an input field with name as ekko-aedat.

And suppose i pass ekko-aedat = sy-datum.

When I go to flow logic and declare in top module as ekko-aedat type erdat and debug the program, then ekko-aedat is blank i.e. no value

however, if i declare tables: ekko

and then debug the program... this time i am getting value in ekko-aedat.

but by decalring tables: ekko is not a good coding practice since i am not using whole ekko table in my program.

Can anyone tell me a work around for this issue.

i also dont want to use dynp_read_values

Hi Suruchi Razdaz,

You are referring

like this ekko-aedat type erdat you are referring EKKO table

use like this data : aedat type erdat.

in screen also maintain filed name like aedat instead of ekko-aedat.

Need not to use Tables : EKKO.

You can try like this for example

*TABLES : YVTABLE.

Types : begin of ty_itab,
         mandt   type mandt,
         carrid type YVTABLE-carrid,
         connid type YVTABLE-connid,
         fldate type YVTABLE-fldate,
         PRICE type YVTABLE-PRICE,
         end of ty_itab.

data : YVTABLE TYPE ty_itab.

DATA : WA_YVTABLE TYPE YVTABLE,
        IT_YVTABLE TYPE TABLE OF YVTABLE.

data : fldate type YVTABLE-fldate.

CONTROLS TSC TYPE TABLEVIEW USING SCREEN 100.
CALL SCREEN 101.

Hi Suruchi,

In PBO event you can default your variable with sy-datum.

In your screen you would have created a field on the layout with a name say 'GV_DATE' of type EKKO-AEDAT right? In PBO, default sy-datum like this GV_DATE = SY-DATUM.

Hope this works. Let us know if you have any issues

Hi Suruchi

Instead of using ekko table structure, use variable or any other local defined types structure in your program.

Types : begin of it_temp,

v_date type erdat,

...

end of it_temp.

Hi,

define screen field name 'AEDAT'.

define data : aedat type aedat. in your program.

specify AEDAT = sy-datum. in your PBO module.

You will get your desired output.
