run_product

I have an Oracle Forms 6i version that was recently upgraded from Oracle 4.5. There are two sequential calls to run_product to
execute a report. I am having a problem with the 6i version in that only the first report is called. In the 4.5 version, both reports are called successfully. There were no changes in the logic between the two versions. Any suggestions as to why the 2nd report is not called when run_product is used for the 6i version?
Additionally, I have tried logging the errors in the 6i version to determine if an error had occurred somewhere between the
1st and 2nd call to run_product. I did not find any errors.
Thanks.
