PO service item - custom field value not copied to GR

Hi All,

I have a custom field in SC,PO and GR. For a sevice and limit items, the value in custom field in PO is not copied to GR. For goods, it is copied.

When I debugged, I found that the system tries to match PO item internal number with that of backend item internal number. If this is matched, the custom field values are copied.

But here it is not matched. What can be the possible reason. Is there any configuration for item internal numbers?

I found a note 848797 for transfer. But exactly at the corrected code in note, program is failing.

Have anyone faced this issue before?

Thanks
