Hello Sagar,
     Without executing the generated Function Module, it is not possible to get the page count of a form in driver program because the generated FM itself is responsible to execute the whole layout and determine the number of pages in the PDF output. The below screenshot shows the number of pages in the structure /1BCDWB/FORMOUTPUT of generated FM after the generated FM is executed successfully.
I really don't know why you need the number of pages before calling the generated FM. But if you still need it, then you might need to call the whole FM cycle twice( FP_JOB_OPEN , Generated FM, and FP_JOB_CLOSE ).
1) First time while calling the FM FP_JOB_OPEN, you need to modify the contents of SFPOUTPUTPARAMS structure. Send the blank values in fields GETPDF, REQNEW and REQIMM, and send the "X" in fields NOPREVIEW, NOPRINT and NOARCHIVE and 000 in field COPIES.
The reason for doing this is, we do not want actual PDF output. We only want to determine the number of pages.
2) Now execute the generated FM . You will get the number of pages in the structure /1BCDWB/FORMOUTPUT-PAGES as shown in screenshot above.
3) Now call the FM FP_JOB_CLOSE as usual.
4) Again call the FM FP_JOB_OPEN. This time you again need to modify the contents of SFPOUTPUTPARAMS structure reversely. Send the "X" in fields GETPDF, REQNEW and REQIMM, and send the blank values in fields NOPREVIEW, NOPRINT and NOARCHIVE and 001 in field COPIES.
This time we need the actual PDF output.
5) Now do the required processing with previously fetched number of pages before calling the generated FM.
6) Now call the FM FP_JOB_CLOSE as usual.
