The issue is not related to SAP but because of some oracle issue. You need to discuss with your Basis team on this and couple of OSS notes are there like 84348, 1023278 etc., and your Basis team can certainly have a look at these notes.
Meanwhile, if your issue is specifically related to bulk generation of excise invoices, why don't you try with J1I3 ?
