A Purchase Request (from FinOps) is a separate record (a 'Request') which is 'linked' to the Purchase Order via a link table in the SQL Database between FinOps and Financials.
A Purchase Request always comes before a Purchase Order, and always after the final Approval Stage of the Purchase Request Approval.
The only time this would not be the case would be if you have raised the Purchase Order directly from within Financials. In which case, you will not see a Purchase Request in FinOps for this Purchase Order.
Once a Purchase Request has been posted, and it creates the Purchase Order, any further processing (such as Receipting of Goods, Invoicing and Paying your Supplier) are part of the Purchase Order processing.
If you cannot locate the Purchase Order in either:
FinOps - POP: Receive Goods
Financials - Outstanding Purchase Orders
Then the chances are, that the Order has been marked as Fully Receipted (all lines are fully receipted, or closed).
You can tell the Order's Status by locating this through the following method:
In Financials, click Creditors, locate your Supplier and click the eye symbol to select the Supplier
Click the down arrow Enquiries and select Outstanding Orders
On the Search window, Order Status filter, select the filter button and include the Status complete
Click Search. You will now see All Purchase Orders, Outstanding and Completed for this supplier
To toggle the Order Status column you may need to click on the CogWheel in the table view and click Configure Columns, then look for and select the Order Status to include this in the view
All Orders with the Order Status of Complete are Fully processed and Completed. Therefore they have no further processing to do.
For the Outstanding Purchase Orders you'll need to click each one individually to view the detail lines for the Order.
This will reveal the Qty Ordered (Total Quantity requested), Qty Delivered (Total Quantity Receipted)
If the Qty Delivered is equal to or greater than the Qty Ordered, then the line is classed as Fully Receipted.
An Order with No Lines Outstanding to be Receipted (Qty Ordered) will not be available for Receipting.
