Problem in creatin target directory?

Hi all,

iam doing idoc to file senario,in receiver side i have to create an xml file for that client have given some naming standards.

the file name at receiver side should like this <fileaname>_<plant>_<timestamp>.xml

filename we can give,but palnt will come from source structure so ihave to use that ,i have 6 different plants so the target directory should be created with diffetent plants. How to do it?How plant will dinamically come in target file name.

regards,

kumar
