What are the steps to default the Expense Types Automatically for Credit Card Transactions?

Hi Everyone,

I am looking for steps to default the Expense Types Automatically for Credit Card Transactions. I am assigning expense types to lookup EXM_CARD_EXPENSE_TYPE but same is not being visible for the task: Expense report template -> Card expense type mapping. So is it ok if we don't assign card expense type to actual expense type here and just define the mapping under manage corporate card Expense type mapping rule?

I found one document on this but that looks like it is very old. How To Setup Card Expense Type Mapping So That Expense Types Automatically Default for Credit Card Transactions? (Doc ID 278060.1). Please share any latest document or steps for this.
