I apologize if this information is already in here, but I could not locate.
Just completed an upgrade from M90 v4.3 to v4.4. For most part went ok until recreating the PO form. Alias is much easier to add field since it is residing in the work file, but for some reason there are suppress formulas in the section expert you have to manipulate to get it to print. Can't tell you how many hours it took me to finally realize this.
Also while the work file is great, they failed to put the phone/fax from the purchase address in the file, they have the phone/fax from vendor maintenance. Had to link this in.
