Enable an SAP R/3 System send Idocs to SAP PI

Maintain the Sender R3 system 1. SM59 : Create a RFC destination to XI
2. WE21 : Create a TRFC Port ->Specify the RFC Destination Created
3. BD54 : Create a Logical System for the Idoc Receiver
4. WE20 : Create Partner Profile ->Maintain Outbound and the Inbound Parameters

Log on to XI System: 1. SM59 : RFC Destination for Sender System
2. IDX1 : Create the port to get Idoc Metadata from Sender System ( The Port Name must match the port name in the idoc header - Usually in format SAP. eg. SAPID1 [Optional Step. Not mandatory]
3. IDX2 : Maintain the Idoc Metadata. This is needed only by XI, and not by other SAP systems. IDX2 is needed because XI needs to construct IDoc-XML from the IDoc. No other SAP system needs to do that.

Idoc Tunneling in XI To prevent performance consuming XMLization and de-XMLization IDOCs are tunneled through SAP XI IDOC adapter meaning no XMLiziation is executed before the IDOC is passed onto the pipeline. Note the message is converted to UTF-8 codepage.
Start transaction SXMB_ADMIN on SAP XI.
Select option Configuration->Integration Engine Configuration and add two parameter EXTERNAL_MAPPER in the category IDOC.
Configure the parameter according to the conditions below:
If Message Code and Message Function are specified in the partner profile:
..ReceiverPort...
If only the Message Code is specified in the partner profile:
..ReceiverPort..
If only Message Function is specified in the partner profile:
..ReceiverPort...


Integration Builder Integration Directory:
1. Add Business System: Adapter Specific Identifiers -> 'Logical System' identical to the 'Logical System Name' in the SLD Business System
2.IDoc Receiver Communication Channel: port the same as XI System IDX1
