receipt and pooled shipment

Hi,

we use E1  9.1 Transportation and Warehouse.

We use pooled shipment,  we follow the explaination of the document E1: 49: How To Create Pooled Shipments (Doc ID 625516.1) to do the set up.

It works well, but the client wants to add a receipt step:

Once the load arrives at the distribution hub,we'd like to updated a status or inventory to mean that the distribution hub has received the load.

how can we do that ?

thanks
