As a requisition preparer, you can change the information on a requisition before you send it through the approval process. To update a requisition you created using the Requisitions window, simply navigate to the Find Requisitions window and query up the requisition. Once you send a requisition through the approval process, your access to it is determined by the security and approval structure.
You may also unreserve an incomplete requisition to reverse any encumbrances.
When you cancel a purchase order line in the Control Documents window, you have the option to either have the referencing requisition lines cancelled or return them to the requisition pool for placement on another purchase order. If you have already partially received the item, Purchasing recreates the requisition line for the unreceived quantity. See: Controlling Documents.
A buyer may want to alter a requisition line before placing it onto a purchase order. The buyer can either return the requisition line to the preparer for changes or simply choose Modify from the Tools menu while in the AutoCreate Documents window to update the requisition line. You can split the requisition into multiple lines so that you can source the requisition across different suppliers. Or, you can change the requisition line if the preparer did not request the item correctly. For example, the preparer might order a computer, though you know you buy computers by ordering the peripherals and keyboards separately. The preparer can later review the requisition to see the original requisition line and the changes the buyer made. See: Additional Autocreate Features.
You can not modify, split, or return a requisition line that references a drop shipped sales order.
Instead of approving a requisition, the approver can reject the requisition and send a note to the preparer to make specific changes. Alternatively, the approver can make changes directly to the requisition without rejecting it. From the Notifications Summary window or any of the requisitions summary windows, the approver can navigate to the Requisitions window and make the appropriate changes, if Approver Can Modify is enabled for the document type in the Document Types window. See: Viewing and Responding to Notifications.
