Handling Messages with PCK 

Purpose

The Handling Messages with PCK IT process does not involve user actions. The Partner Connectivity Kit (PCK) processes inbound messages from the sender application and sends them to the Integration Server. The Integration Server processes the messages from the PCK and sends them to the corresponding receivers. Message processing can run through integration processes on the Integration Server. These integration processes are mandatory for the Business Process Management scenario.

Use of the Process

This IT process is part of the following IT scenarios:

IT Scenario	IT Scenario Variant
Enabling Business-to-Business Processes	Small Business Partner and Subsidiary Integration

Prerequisites

This process depends on the inbound message and the previously created configuration objects. These must be available in the Integration Directory and determine, for example, the receiver or receivers of a message.

Process Flow

The process runs in the PCK and in the usage types AS and PI:

...

       1.      System sends message (external system)

The external sender system sends a message.

       2.      System receives message (PCK)

The PCK receives the message.

       3.      System determines receivers (PCK)

The PCK determines the receivers for the message.

       4.      System executes mapping (PCK)

The PCK executes the mapping agreed between the sender and receiver.

       5.      System sends message (PCK)

The PCK sends the message to the Integration Server.

       6.      System receives message (PI)

The Integration Server receives the message.

       7.      System determines receivers (PI)

The Integration Server determines the receivers of the message.

       8.      System executes mapping (PI)

The Integration Server executes the mapping agreed between the sender and receiver.

       9.      System sends message (PI).

The Integration Server sends the message.

   10.      System instantiates process (PI).

The Business Process Engine instantiates a process.

This step is only mandatory for the Business Process Management scenario.

   11.      System performs correlation (PI)

The Business Process Engine performs the corresponding correlation.

This step is only mandatory for the Business Process Management scenario.

   12.      System executes process step (PI)

The Business Process Engine executes the process step.

This step is only mandatory for the Business Process Management scenario.

   13.      System sends message (PI).

The Integration Server sends the message.

   14.      System receives message (AS)

The receiver system receives the message.

Result

The inbound message is processed and sent to the determined receiver or receivers.
