You are a using Lean HCM without Personal administration work center, when creating a new employee, it is not possible to maintain the payment data via Business partner work center. Because of this it is not possible to create financial outgoing payments for employees via bank transfer.
If the processes like financial outgoing employee payments via bank transfer are essential for you then you have take Human Capital Management in your system scope. The maintenance of employee financial data is not (should not be) supported if HCM is not in scope - even if you are able to migrate such data.
This is general system behavior.
Note: Lean HCM scoped system only supports to pay employees via petty cash
