HOW TO AVOID DUPLICATES WHILE USING VRM FM

[Former Member]

HI EXPERTS,

I AM USING VRM FM TO PASS VALUES INTO LISTBOX IN SCREENS.FIRST TIME IT IS WORKING PROPERLY WHEN I USE IT FOR THE SECOND TIME IT IS SHOWING THE PREVIOUS DATAS ENTRIES ALSO .HOW TO DELETE THE DUPLICATE ENTRIES OF IT .

THIS IS MY CODE.

when 'ENTER'.

select POSNR ARKTX from LIPS into corresponding fields of table i_pstyp WHERE VBELN EQ VBELN.

LOOP AT I_PSTYP .

W_DDLIST-KEY = I_PSTYP-POSNR.

W_DDLIST-TEXT = I_PSTYP-POSNR.

APPEND W_DDLIST TO POSNR1.

CLEAR W_DDLIST.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = 'POSNR'

VALUES = POSNR1.

IN THIS IF I SELECT NEXT VBELN WITHOUT EXITING FROM THE SCREEN THE PREVIOUS VBELN'S LINE ITEMS ALSO ARE DISPLAYING .WHAT SHALL I DO .

       into corresponding fields of table i_pstyp
       WHERE VBELN EQ VBELN.

W_DDLIST-KEY = I_PSTYP-POSNR.
W_DDLIST-TEXT = I_PSTYP-POSNR.
APPEND W_DDLIST TO POSNR1.
CLEAR W_DDLIST.
ENDLOOP. " Endloop here. the FM should not be called inside the loop

CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING
ID = 'POSNR' " hope you are using the fieldname correctly
VALUES = POSNR1.
CLEAR : POSNR1. " this will stop repeating the values in your drop down list

<b>refresh POSNR1.</b>

LOOP AT I_PSTYP .

W_DDLIST-KEY = I_PSTYP-POSNR.

W_DDLIST-TEXT = I_PSTYP-POSNR.

APPEND W_DDLIST TO POSNR1.

CLEAR W_DDLIST.

endloop.

Hi ...

This is bcoz the Values in the internal Table are retained.

So you have to remove the entries before calling the function module

Like:

REFRESH POSNR1.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = 'POSNR'

TABLES

VALUES = POSNR1.

Hi,

Try this.....

use REFRESH posnr1 after fm.Using this stmt the previous body contents will be deleted.So for the next time new contents gets displayed.

Hi..

I m sorry.

You have to Use the REFRESH before the LOOP where you are APPENDing the values. Not before calling the FM.

Plz correct.

Regards.
