How to set field value in a field marked as external?

You could probably do direct db update, but you take your warranty in your hands when you do so.

(Lesson Time:)
When Epicor adds a new feature, sometimes the developer needs to add a new column to a database, but this cannot be done without changing the schema.
BUT, they can add a temporary PatchFld to the PatchFld table. This then allows them to implement a new feature, and then the next release where the schema is updated, the move the data from the PatchFld table to the regular table.
Sooo… Create a Query in the PatchFld table, filter on TableName = PartPlant, and display the Field, Foreign Key, data type, and then the other data fields… I am GUESSING you will find your field here.

From DB Schema Info:

PatchFld : Patch Fields. A generic table used to provoide a temporary storage location for new fields that need to be implemented within a patch before a schema change can be made. The intent is that during the next schema change fields will be created to hold this data and a conversion program written to migrate it
