excise invoice already exists error in J1IS

Hello

Created the Subcontracting PO , and Issue the material to vendor ( mov type 541) with payment of duty, after this created the Excise invoice with T.code J1IS, system was generated the Excise entries in table J_1IEXCDTL and J_1IEXCHDR.

After that we have reversed the excise entries, so now we got "R"Indicator in status field in above said table J_1IEXCDTL.

Now system should allow me to create one more excise invoice with same Material document number but sytem was giving error message that "excise invoice already exists"

Why system was allowing us to create new excise invoice?

Regards
