You use port management in the IDoc adapter to establish an RFC connection to the system that contains the metadata. The IDoc adapter requires this metadata to be able to convert the IDocs (Intermediate Documents) sent to it into IDoc XML. The system is defined by the sender port and the client in the IDoc control record. It is either the sender SAP system or an SAP reference system.
The metadata comprises the IDoc structures for the corresponding IDoc types. Using this port you can call this data either directly at runtime or you can load it to the Integration Server beforehand.
You must manage a port in the IDoc adapter for all clients in each SAP system that you want to connect to the Integration Server using IDocs.
This is also the case for receiver systems if they are subsystems (non-SAP systems). Systems of this kind are defined using the receiver port in the respective communication channel.
To establish an RFC connection in the IDoc adapter, proceed as follows:
On the left-hand side the system displays a list of ports that are already defined, for example SAPABC_123, and a description.
The system converts the display area on the right-hand side of the screen into an input area where you can enter the specifications for the new port.
For SAP systems this comprises the type and ID of the connected system, for example, SAPABC.
This comprises, for example, the system ID and the client, for example, ABC_123.
The specifications for Port and Client correspond to the sender port and the client in the IDoc control record.
The system places the entry alphabetically in the list of defined ports.
The system converts the display area on the right-hand side of the screen into an input area where you can make your changes. The port name and the client cannot be changed.
Select the port from the port list and choose Delete ().
