Dear Expert,

I have requirement where when purchase order created using me21n, purchase order form need to

create in the PDF format and save in the local Desktop.

I have found the program RSTXPDFT4 which convert the form into PDF, but i think spool need to

create the spool and input into the program.

whethere we have any other method where we can save the po form in pdf when creating po using me21n.
