Supplier portal invoice match

we have a Purchase Order line with the following details: -

1- Receipt routing: inspection required.

2- Match approval level: 3 Way

3- Invoice match option: Receipt

We received the purchase order "Initial receipt" in the receiving area and still awaiting inspection and put away.

When we try to match this purchase order line in AP invoice lines can be shown and matched, however from the Supplier portal side no lines appear except when the put away step is completed, is this a normal behavior ? and how to be able to match invoice from portal on Receipt regardless put away part.
