Information in this document applies to any platform.
After you start processing a Purchase Order (PO) Upload, you see the deadlocks for an existing Item Upload which eventually causes the PO Upload to perform slow.
Though Item and PO Upload belong to different AQ, these two AQs feed into one DB Scheduler. Hence, expect the application to provide a way where the user can define or feed in the scheduler to reduce the contention.
The issue can be reproduced at will with the following steps:
1. Start Item Upload and PO Upload in parallel.
2. Notice the deadlocks.
