What happens if no credit currency is defined?

You can use the AR: Default Credit Management Currency profile option to define a default credit currency. The credit checking process uses this currency if no credit currency is defined in the applicable customer, customer account, or party profiles.

If the AR: Default Credit Management Currency profile option isn't defined, the credit checking process uses US dollars (USD) as the credit currency.

If no conversion rate type is defined, then the credit checking process uses the conversion rate type Corporate.
