When you are entering a Warehouse Transfer you receive the following error:
"Error 88: Invalid/unknown property name
O/S Error: No such interface supported [err/ret=2/0]
Make sure that when starting the transfer the SHIP VIA field is populated.
It is important to note that the Ship Via must be populated from a code existing in the drop-down. Entering any random code will cause Error 88.
Make sure that the tax schedule is set to NONTAX - this will remove AvaTax from the equation and allow the transfer to go through and issue the related Purchase Order.
