Approval Process in Sales Order as in Procurement

Hi,

I know that there is no way to apply an Approval Route to the Sales Order Process, as in Procurement Process with standard JDE functionality.

Just want to know how this can be achieved in sales?

Can we use multiple credit hold process? Can we set credit holds based on amount range as we do in procurement approval route code?

Does system places all credit holds in a single order such that when C1 credit is approved, C2 hold should fall on this.

Regards,
