Approved Requisition - How to return & retain the status as Approved.

Hi,

There is a business scenario.

1) The purchase requisition has been duly approved by all the stakeholders in approval hierarchy for amount and quantity.

2) The PR (Requisition) is with Procurement team and they found that BOM (Bill of Material) is missing or probably they require some additional document.

    Hence, wants to send it back to original team which raised the PR.

Business Objective:

1) How to return it to requestor / preparer and retain the status of IR as approved itself.

2) Once the information  / additional document is ready - the Purchase Requisition can directly be sent to Buyer / Procurement team since, there is no change in amount/quantity.
