Hi Kristine, I think I might have a way to address this for you. About a year ago, we adapted our "https://store.atappstore.com/product/ubercalc/" UberCalc solution to allow one of our client's Workfront SysAdmins to upload a fresh version of their SAP Inventory Parts List (think "+50,000 row text file each morning") into Workfront. With that file in place, on a special form housed within Workfront that we built for this very purpose, end users can use typeahead on any of the three major components that make up an inventory number to instantly filter down to only the numbers that are valid within that file's contents, effectively eliminating data entry errors, since our form will ONLY allow a valid selection to be saved back into the underlying Workfront custom parameters. Although we've not yet decided whether to create a "https://store.atappstore.com/products/all/" catalog entry for it, our solution effectively allows us to extend Workfront's data model and provide business rule based field validation. If you'd like more information, I invite you to email me at doug.denhoed@atappstore.com. Regards, Doug Den Hoed - AtAppStore
