Oracle Product: Oracle EBS R12

Version: 12.2.0.4

Detailed Question:

We are planning to separate 1 concurrent request (Sales Order) as this request is a high priority and we would like to ask which is more better on these two options:

1. Create one (1) Concurrent Manager for Sales Order only (Actual & Target = 40)
2. Create two (2) Concurrent Manager for Sales Order only

• Concurrent Manager #1 (Actual & Target = 20)
• Concurrent Manager #2 (Actual & Target = 20)
