Hi all,
i am uploading multiples files from desktop to application server and its working good. But user can upload same file name more than 4 or 5 times together.And i have to write the file on server by appending _2 _2 _2 for every new file. Right now i am able to do for one file name(.i.e. the file if already exsist its appending _2 with the new file name). but if i am uploading the same file third or fourth time its not writting the file on server. I have to just append _2 _2 with file that already exsist.
here is the code that i had built up...
DATA: BEGIN OF t_itab OCCURS 0,
soldto(10) TYPE c,
enumber(10) TYPE c,
ename(35) TYPE c,
land1(35) TYPE c,
name2(35) TYPE c,

invoiceno(35) TYPE c,
scost(13) TYPE c,"DECIMALS 2,
ucost(13) TYPE c,"DECIMALS 2,
dlno(10) TYPE c,
END OF t_itab.

For each file, do the following 3 steps.
OPEN DATASET myfile. DO. READ DATASET myfile. IF SY-SUBRC = 0. *-- file already exists, append _2 to the file name CLOSE DATASET myfile. CONCATENATE myfile '_2' into myfile. ELSE. *-- file doesn't exist EXIT. ENDIF. ENDDO.Could not help noticing, after your WS_UPLOAD(this is obsolete, do not use this), you are doing a CONVERSION EXIT for itab-soldto without looping at the internal table.

Srinivas
