ASCP not collecting Standard POs created for Consigned Items

We have  consignment items where setups are as follows

1) ASL and Sourcing Rules done (consignment check box checked in ASL,INV tab)
2) Autocreate Option is set to "Automatic review.

From ASCP planned orders are converted into Purchase Requisition.
Further PRs are converted into Standard Purchase Orders with status : closed for invoicing.

In next collections Standard Purchase Orders are not collected.

Any pointers to address this issue are appreciated.

Thanks!
