Issue in saving file into Application server

Hi Expert,

i am tring to save file into the application server using open data set statment.

   OPEN DATASET W_FILENAME FOR OUTPUT IN TEXT MODE ENCODING DEFAULT .

using this i am successfully able to save file into one directory of the application server .

but in the other directory (Which is newly created ) , i am not able to save file it is giving me Sy-Subrc = 8 .

what could be possible reason for not saving file into new path in application server.

how can i overcome from this issue.
