We are redesigning a component called the Catalog Profile and it drives codes we use in the workflow. The fields the codes are in rely on reference data. The legacy codes won't be in the reference data, but they can come down with the source work order. When the legacy codes don't match anything in the reference data table, the MWFM system produces a blank. We'd rather that the legacy code was able to display, but not be selected from the drop-down.
