In t.code J1IJ RG23D selected wrong excise invoice for delivery document.

Dear sir,

I have done PGI 15 qty for my customer and RG23D selected in t.code J1IJ for 10 qty but i am not able select excise invoice for remaining 5 qty.

Reason-This 5 qty alredy selected wrongly for other delivery.

Please let us know the solution for capturing excise for the pending 5 nos..
