Business Number generator Issue

Hi All,

We have one requirement for generating business number for invoice. We need to add SCAC code as well as invoice number as invoice id.
To achieve this, I have created a new BN Type with id as INVOICE_XID and BN Context as INVOICE_CONTEXT and i have created the rule definition.
When I test this BN using action, TEST BN RULE, it works fine. But when I am trying to integrate a new invoice or try to create new invoice manually it is erroring out. below is the error message
" CAUGHT THE FOLLOWING EXCEPTION WHILE PROCESSING TRANSACTION: No default rule found for type=INVOICE_XID, domain=<<Custom Domain>> at sun.reflect.GeneratedConstructorAccessor992.newIns tance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.


Kindly help.
