A little late to the party but take a look at this thread : Advanced Search SugPODtl - #7 by pawel.malicki
1- Add the field SugNum to the grid or add a textbox binded to this field in a temporary customization
2- Right click on the field - quick search
3- Create your quick search and check the Base default check box, otherwise it will never show. This problem seems to be specific to the New Po Sugg menu
