Working on an inventory look-up project to help avoid bad user input and data. Switched a key look-up from a user-defined text look-up into a more controlled id look-up. We had to leave the flexible look-up for certain things and create a switch that allowed for both text and id look-ups on the same method. We've done this tons of times, we just had to do it and then follow all of the connecting paths and figure out which value to pass and base things off of. Cascaded the changes, tested, merged in code, and pushed it up to all of the servers.
