Corporate Card Mapping - How to map the issuer's industry codes to card expense types?

Summary:

Hello,

I'm having difficulty mapping the predefined corporate card expense types to the corporate card issuer's transaction codes. The corporate card expense types are configured and mapped to the user defined expense types. I have the card issuers transaction codes defined in the "Manage Standard Industrial Classification Codes" task. I see no documentation online explaining how to link the expense types with the issuer's codes. The issuer is a bank with a few custom industry transaction codes that are not pre-defined in Oracle.

TLDR: I'm not seeing how to map the industry codes to the corporate card expense types.
