PRs are not converted to PO although the PRs are approved.

Summary:

Few PRs are not converted to PO although the PRs are approved. Upon investigation, I could see the following REQTOPO_AUTO_FAILED_REASON,

1]PO_RTP_SUPP_INACTIVE - Supplier is active but when it is checked at supplier site level based on procurement BU, it shows a message in the control section 'hold all new purchasing documents' at site level. So, is this the reason for POs not getting created that belongs to specific BU and suppler?

2] PO_RTP_ITEM_NOT_PURCH - upon checking, could see that item is active but still PO is not generated.

3] PO_RTP_PA_NOT_EFFECTIVE - effective end date of the BPA has been extended but still PO is not generated.
