UPDATE: After searching around, it seems what I am looking to change is the identifier for a given entity. Is this done simply by exporting the application definition, changing it and then importing it again? And what are the consequences if the entity is being used in multiple places already?
We have a "Document Type" entity in our site with the following fields:
ID System.Int32 Long Name System.String Short Name System.String
The ID is a numerical unique ID, while the other two are textual representations. The field is always set to show the "Short Name", which is a 2- or 3-letter abbreviation that is easily recognizable and known by all our users.
However, to enter the value directly into the field, without using "Browse", they have to enter the ID (usually a 5-digit integer), which is hard to remember. Is there any way to make the field accept the "Short Name" value without using "Browse"?
Example: I enter "12345", press "Check Names" and the document type short name "PO" shows up correctly. If I enter "PO" directly and press "Check Names" it says "No exact match was found" - I want to accept "PO" as-is without having to press "Browse" and search for it.
