EXPORTING LIST TO MEMORY

[Former Member]

- I want to call another program (prgB) from within a program (prgA).

- Export the results from prgB to memory

- Import these results to prgA, do my processing and,

- Then Free the memory

I am using the below code but my itab_list is not populating. It simply contains all zeroes despite the fact that the calling program has succesfully worked.

SUBMIT rplabsg0_sxp_oxp_hist

WITH pnpbegda = cal_start_date

WITH pnpendda = cal_end_date

WITH pnppernr-low = pernr-pernr

WITH s_type IN it_type

EXPORTING LIST TO MEMORY AND RETURN.

LISTOBJECT = itab_list

OTHERS = 2.

IF SY-SUBRC <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

,,

just check this out and let me know ..

by the way put a break point on itab_list and see if this is getting populated.

Hi,

Run the program with the same selection parameters that you are passing through the program and see if generates a list indeed.

The calling program is producing a list fine. The trouble is that it produces an ALV list, which means the user has to back out of the program (prgB) to return processing to (prgA). I have tried using the 'export to memory ID', 'import from memory Id', but like I said this still produces prgs B ALV list.

What I want to do is similiar to using the spool parameters capture prgBs results (without the need for the ALV grid) and thus retunr to prgA without user interaction. Accordfing to SAP help the 'Submit... EXPORTING LIST TO MEMORY' should not display the ALV output list, but when I use the above code it does???

Hi ,

u mean to say that the called program is producing an ALV o/p

and u need to fetch the data from that ..

just create two abap programs in ur dev server like this ..

im giving u two programs .. just execute the same ..

see the second program gives u an o/p in alv list ..

now im reading the content from alv o/p list to my program in a

this is the process..

first program.

Thanks that helped a lot. The problem I had was the program that I was calling was using 'REUSE_ALV_GRID_DISPLAY' to produce the results, whcih doesn't appear in SAP memory. I cahnged it to use 'REUSE_ALV_LIST_DISPLAY' and I was able to import the results to my program...Thanks again.

[Former Member]

The thing is u need calculate the number of spaces that the TOP-OF-PAGE is taking when u use ALV grid Format ..

and then skip the lines and hold ur data ..

itab content is there mate ..

only thing is u need to get it ..by skipping that top of page portion ..

try doing this in debugging ..

glad that u got the edge ..

regards,

VIjay
