Special Carteira: Boletos Issued by the Vendor 
For vendor operation, use payment method V together with print program RFFOBR_V.
For duplicata, use payment method D together with print program RFFOBR_D. Create a new check lot for the respective bank account and enter payment method D in the payment method list.
To assign the correct Boleto form to print program RFFOBR_D, you need to enter this form in the Alternative Boleto form field on the selection screen of this program. The SAP standard form for ITAU Boletos, J_1B_BOLETO_ITAU, is set as the default. This form refers to the layout of a Boleto for Itau. If you wish to also create boletos from other banks such as Bradesco, you need to create a specific form according to the respective layout. The easiest way to do this is by starting with a copy of the Itau form.
However, apart from the layout, certain banks may require data on the boleto different from Itau or Bradesco. This may be the case particularly for the control digit for ‘Nosso Numero’, as well the numerical and graphical barcode, because used algorithms for control digits may differ from bank to bank. In these cases, you can implement a user exit via Transaction CMOD and enhancement J1BF0001.
Boletos are handled using the standard check management - so its whole functionality is also available for Boletos as far as it is sensible in this context. In particular, this comprises number range maintenance and administration through number lots.
For the used bank account and payment method (D), the corresponding carteira number must be defined as bank transaction.
