Query on Approval Limits

Hi,

For Manual Requisition or Purchase Order approval , we know that Position or Employee/Supervisor can be setup which will follow an amount based hierarchy.

However here the requirement is that once Oracle Planning runs, then Requisitions created which are under a certan $ value should be autocreated to a Release while those Requisitions which are above a certain value SHOULD NOT be autocreated to a Release. Rather, it should be reviewed by a Purchasing person before approving and getting converted to a release.

Is this requirement possible using Standard setups?
