dynamics gp 10 drop ship with econnect

Hi,

I would like to replicate GP's manual vendor drop ship process using econnect.  Questions below.

STEP 1.  Enter Order.  Already doing this with econnect.

STEP 2. Purchase.  I can create a drop ship PO with econnect.  Can it be linked to the SOP order with econnect?

STEP 3. Invoice Vendor.  Is this possible from econnect?

STEP 4. Transfer Customer Order to Customer Invoice.  Is this possible from econnect?  Or would I need to delete the order and insert a new invoice with econnect?

STEP 5.  Post the Customer Invoice.  Is this possible from econnect?

Thanks,
William
