T4 recharge transaction assigned 2 doc numbers

Has anyone ever come across the same T4 recharge transaction in the same batch assigned 2 document numbers from Next Numbers P0002 ?  I'm getting an out of balance R09801 and I think it's because each document number does not have an offsetting transaction to balance it, even though the batch is in balance..  Here's an example of my transaction.

Batch   Doc Ty  Doc Num    Co    Debit    Credit

1234       T4            497         1   100.00

1234       T4            498         1                100.00

Any help would be appreciated.  I have submitted an SR with Oracle but still waiting with no word yet.

Thanks,
