Method of Payment link to a Ledger (not to a Bank account) error message

Hi,

I am trying to create in AR Module a method of payment that will be linked to a ledger and not to a Bank account. But I am getting this error message 

Function DimensionValidation::newForValidationRequest has been incorrectly called.

On the Payment Control  I didn't select that Bank transaction type is mandatory. But for some reason only Bank accounts are accepted on the set up of Method of payments.

Thanks for your help.
