Requestor phone number in iSupplier portal ?

Hello,

When we click on the Purchase Order number in iSupplier portal, we can see the Purchase order details.

In the Purchase Order, shipment details ( may need to click on show all details ) you can find the requestor name.

once your click on the requestor name hyperlink, you will find the details of the requestor.

Now where are these details coming from ?

Is it HR record ? If yes. what is the navigation.

We are especially looking for the phone number field which are blank as of now.

We wish to populate them accordingly.

Many Thanks,

Emma
