how to select a file using F4 function module for application server?

Former Member — Wed, 12 Sep 2007 10:34:15 GMT

Hi all,

i wanted to get the F4 help on the selection screen parameter for the file name to fetch the file from the application server. I have a file been created in the application server.

i have used following function modules:

1. F4_FILENAME_SERVER

2. RZL_READ_DIR_LOCAL

3. F4_DXFILENAME_TOPRECURSION

4. /SAPDMC/LSM_F4_SERVER_FILE

5. EPS_GET_DIRECTORY_LISTING

6. F4_DXFILENAME_4_DYNP and so on.........

i am able to get the f4 functionality but i am not able to get any value in the selection parameter when i select a particular file on the application server listing.

please help me in solving the issue.

thanks

ekta

Hi..

Actually it is not advisable to do F4 an select the file from Application server..

It is always better that either user enters it or it's hardcoded.

In case just chk ur parameter type is it "rlgrap-filename"??

Thanks for replying,

But it has the same problem that when i select the file it does not shows in the parameter of the selection screen.

the field remains blank only.

thanks

Hi,

In Vasu's code instead of

IF SY-SUBRC <> 0.

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

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

ENDIF.

Use :

IF SY-SUBRC <> 0.

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

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

ELSE.

P_HEADER = V_HEADER1.

ENDIF.

Please ensure that Vasu is rewarded for this as He has given you the solution.
