How to identify the supply order number comes from which plan name?

Hello,

I want to know how dentify the supply order number comes from which plan name in Manage Supply Lines screen.

Users have 2 MRP plan based on some business requirements.

Such as

1. MRP-1 is for execution order
2. MRP-2 is for simulation

But sometimes, user miss-operated to relase some planned order from MRP-2 by manual.

So I want to know which supply order number was came from MRP-2.

Thanks, Akiba
