Run Report from a form in R12

Dears ,

We are upgrading from EBs 11i to  EBs R12 (12.1.3) .

on 11i we had a cusomized form where we used to use RUN_PRODUCT to run a report from a form .

now on R12 ( 12.1.3) the RUN_PRODUCT is obsolete and cannot be used .

Can you please help what solution shall we use to run a report from a form in R12 (12.1.3) .

I know this can be done through the concurrent request but we prefer if we can find another solution.

I was trying to use the run_report_object but did not succeed and not sure if we can use it in R12.
