When an intercompany purchase order is set up within D365, it asks you for the lending entity project and cost centre, this stays in the purchase order header but on the lines page. There is the option to change the lending entity dimensions line by line within the PO but whatever is first selected at the point of PO creation overrides this either way so it is a little misleading having the lending entity project and cost centre within each line if this does not reflect in the sales order and it goes to one place.
