Setup Blanket POs and resulting OP type orders not to go through approval process

Hi All,

A quick Q. I am implementing non stock procurement in a new 9.1 environment.

We are planning to use OP Order Type with Line Type 'J' with PO approvals working. Now we want to use Blanket Orders as well (Order Type - OB). Qs are:

1) Can we use OB order type with Ln Ty 'J' as well?

2) Since OP Order Type will be getting generated from OB, how do we ensure that only OB Order Type POs will go for approval and subsequently OP order type POs (getting generated from OB) will not require approval and will be ready to be printed/matched?
