The obvious extension to Item Category Codes (which can be assigned hierarchically), are Item Attributes. These naturally allow for custom categorization of items. Consider fasteners as and item category parent with nuts, bolts and washers as item category codes. Item attributes for washers might be material, thickness, inner diameter and outer diameter. Users set up the custom attribute Material with a drop-down list of options, Thickness, ID and OD would be specified as decimals. This is built-in behavior.All MS needs to do is add attributes to the other master records like Contacts, Customers and Vendors and we're there.
In our warehouse we have 5 employees using the same pda, in addition to seeing what warehouse you are working in, it would also be very useful to see the user the pda is logged in with. We are a part of a big company but in Spain the warehouse is small and there is not a fixed user assigned to the warehouse, there are five different people doing transactions with the same pda.
