Diagnosis
Transaction &V1& either has no flows that can generate payment requestsor only has flows that must be paid individually.
Since these flows cannot be transferred to the payment program oralways have to be paid individually, it makes no sense to assign thistransaction without relevant flows.

Procedure
There are three possible reasons why the transaction cannot generatepayment requests:

• On the payment date concerned, the system only found flows with flow
types that do not permit payment requests.

• When you created/changed the transaction, no standing instructions were
maintained that allow generation of payment requests.

• The indicator for generating payment requests was deactivated for the
transaction or for the selected flow.
Check your Customizing settings for flow types, the standinginstructions for the partner concerned and the currency/payment detailsof the transaction itself.
The same also applies to the indicator Individual payment required
