Hallo Roswitha,
there is a partner, that offering a solution for such integrations between banks and ERP systems. It is used by a few ByDesign customers already. The solution has a connector for ByDesign, which allows direct communication.
The company is TIS Treasury Itelligence Solutions (http://www.tis.biz/en).
If you want, I can sent you the data of our contacts.
Best regards
Marlene
