Interface Trip Stop(ITS) and Excise Invoice generation is taking too much time in EBS 12.2.4

Hi,

We are migrated from Oracle EBS 12.o.6 to EBS 12.2.4.

In a 12.o.6 ITS and Excise Invoice generation are two different activitys.
- After ITS completes user will manually run the excise invoice generation program.

But in Oracle EBS 12.2.4 once ITS completes system will auto generate the Excise Invoice.

We are following the same process and shipping the same Quantity in 12.2.4, but ITS is taking too much time to complete.

If any body faced the same issue or if any body have the solution please update.

Thanks

Bashu
