Payroll and travel (travelnumber)

Hi

I don't know if it is the right forum, but I can't find any that are more relevant...

In the FM: HRCM_PAYROLL_RESULTS_GET

we have information for the payroll, and also from travel.

I also need the travelnumber, so it can be printed on the payroll.

Can anyone help me with a link between the travelnumber and that function module ?

Or is there another solution ?

Hope my question is clear.
