We upgraded Vertex O series from 5 to 7.
We now see intermittent issues where Vertex responds and SAP is not taking the value. For instance, Iowa freight is non-taxable. When we invoiced the customer, Vertex logs show response of $0.00 tax for the freight. However, SAP set the value at $1.11.
We cancelled and rebilled and it processed fine, with $0.00 tax for the freight line.
Has anyone experienced this or know how to fix?
