Counters retrieval on service order

Hi,

We have created one custom program to create and assign counters to Vehilce (I objects in our case without IBASE).

.While creating service orders, we are giving Iobject in the header as product ID. Our requirment is to retrieve this counter in service order counter and reading assignment block. I would really appereciate if somebody could help to me achieve this requirement.
