MIR4 - Changing adress and bank information for one-time account

Hi,

for a automatic invoice process we park the vendor invoice automatically with the extracted data from the paper invoice. This works. Now we would like to use one-time account for logistical these invoices. Our program can create the parked vendor invoice with dummy-bank-account informations via BAPI. But in Mir4 I am missing the button to change the one-time account data (address, bank information, ...) that I have in MIR7. How can I change this data in the MIR4 transaction?

Regards, Vanessa
