This one is pretty important.
I was reading thru’ the GP Partner Forum and learned that PO Integrations using eConnect 10.0 SP4 fails with the message: Microsoft.Dynamics.GP.eConnect: Number = 8701 Stored Procedure taPoLine : Description = Document Date is required for PA
Original Link: eConnect failure in integration manager taPOLine.
MSFT responded back saying that this is a bug and will be rectified in the coming Hot Fix.
So those who are updating eConnect 10.0 to SP4, kindly be informed about this and make sure that you are keeping track of the Hot Fixes which MSFT is going to release in future.
