Do you have any vendor that has several bank accounts? Sure you do, if you deal with big companies. They tend to have different accounts for different tasks and/or divisions of their business.
Then you need to make payments to these vendors.
How do you set up these payments to go to the correct bank account then?
That is quite easy.
The Payment details tab in the vendor master data has a list of bank details: bank key, account number etc. One of the fields there is Bank Type. You can enter any value up to 4 characters there.
When you do this, you have an ability to use this identification in the invoice. I.e. you tell the system that the payment for this particular invoice should go to this particular bank account.
The payment program will pick up the information and create a payment document with the correct bank details.
