Spool to PDF

Hi All

I have created a spool for a SAP script now i want to get the OTF format into an internal table and pass the OTF internal table to use this internal table in the FM CALL FUNCTION 'SX_OBJECT_CONVERT_OTF_PDF' which will give me PDF format. My problem is in the 3.1i version we used CALL 'RSPOACSD'(call cfunc) to get the OTF data into the internal table. Now in ECC5.0 Call cfunc are obsolete. can any one help how to go about this.

Regards,
