Recurring billing plan does not accept transaction source
Summary: When trying to create a recurring billing plan for a specified business unit, the already set up transaction source is not accepted.
I work with two business units. Just one accepts creating recurring billing plans. The other one, although previously setting up the transaction source and transaction type, the transaction source is not available.
What could be missing?
