ExciseInvoice(J1IIN)raising wrt second Bill No(SamesSalesOrder forBothBills

Question

Dear All,
I need your suggestion in a scenario which is as follows:
This is Make-To-Order scenario. In the Sales Flow both PS and SD Modules take some part.
The FLOW is Sales Order in VA01; Delivery creation in CNS0(PS); after doing CNS0 picking, packing and Goods Issue will be done through VL02N.
Billing will be done in VF01(Accounts Posting is done from this; This Bill was created with reference to Sales Order, since Billing Plan is there in the Sales Order). Then by going to J1IIN, Excise Invoice is raised with refrence to the Bill No that was generated in VF01.
The situation here is as follows.
The material that the Client Delivers is huge(1000 Ton).
That is why the Client is doing Partial Dispatches.(Material being huge
Now whenever they do the Dispatch(partial) they will raise the Invoice for the corresponding part value and post the Details into FI.(Say for Part 1 they will raise the Invoice. Here the invoice will contain part1 value only)
Now the problem here is that I was not able to raise the Excise Invoice for the Invoices later than the starting Invoice.
{Say, while Dispatching Part1 Invoice 101 has been raised.
For part2, Invoice 102 has been raised.}
Now I have raised Excise Invoice(J1IIN) for Part1 by reffering to Invoice 101.
BUT WHILE RAISING THE EXCISE INVOICE FOR PART2 by REFFERING to Invoice 102, system is giving the following error:
" MODVAT UTILISATION has already been done for Invoice 102 and Delivery No. HM001"
Here Delivery No. reffers to Order No.(The point to note here is both the Invoices were raised by reffering to same Sales Order No.).
So I need to know whether I can raise the Excise Invoice again for the second Invoice. Here I should be able to raise the Invoice for the second time also since the part2 Excise Duty value is not yet posted into CENVAT A/Cs.
Please give suggestions so that I can  do this process in a better way to solve this problem.
Regards,
Raj Kumar Reddy Poli.
