Does SAP have an Mailing Address verification module and if not what do they recommend for this? We do not check the City, State, Zip entered into IT0006 to make sure it is correct, we just accept what is entered. This is causing problems on the FI side when an Employee becomes a Vendor and his information is pulled from HR. When they take an address and run it through VERTEX to find out the Tax Jurisdiction and the ZIP doesn't match the city, VERTEX returns an error. As a result we are looking at possibly starting to verify IT0006 information.
