Companies use enterprise resource planning systems. Some companies develop their own ERP systems just like Robert Bosch but other companies rather buy an ERP system from the market for example Johnsons Controls Inc. They have used SAP developed system. Those companies which buy an ERP system from the market have to customize it for their own requirements before they can apply it. That process called the ERP implementation.
The different ERP systems have to be able to communicate with each other. This communication is a data exchange without human assistance. There are given standard formats and protocols considering this data exchange such as the EDI protocol that connect two different ERP systems and provides automatic data transfer.
I solved a problem of connecting two different ERP systems in my thesis. I used EDI based communication. I developed the system interface which is responsible for data conversion for sending and receiving data considering the EDI standards.
So far the ERP system only know the internal processes but now the ERP sys-tem can handle external processes thanks to development of systems.
