Internal requisition (IR) has 2 items with different Source and destination Orgs. On creating Sales

Hi

In our scenario, there is an Internal Requisition with 2 items. IN both items, the source and destination Inv Orgs are separate (So  in all we have 4 diferent Inv Orgs- 2 per Item).

On doing Create Internal Order and Order Import, the system generates only 1 order containing only 1 item. Also, the next order number is 'skipped' (eg 200060 is created but there is no such number as 200061- The next order number comes as 200062).

Could anybody please suggest what could be the issue here?

Thanks,
