Enabling Multi Channel Access in the DOE 

Use

The Data Orchestration Engine (DOE) exchanges data with a receiver through a channel. The DOE allows you to create a channel and then associate receivers with this channel.

For example, you can define an RSS channel that exchanges data between the DOE and an RSS reader. The default channel provided in the DOE allows the SAP NetWeaver Mobile client to exchange data with the DOE.

Prerequisites

You have a basic knowledge of ABAP, and you know how to implement methods and classes in ABAP.

Procedure

To enable the DOE with a new channel, you must perform the following steps:

...

       1.      Determine the channel attributes.

A channel is characterized by the connectivity and protocol. You must determine these attributes for the channel.

More information: Determination of Channel Attributes

       2.      Create the channel in the DOE based on the decided attributes.

More information: Creating a Channel in the DOE

       3.      Define the channel handler.

A channel handler is an ABAP class that you define for the channel. The channel handler must implement the interface according to the channel type (inbound, outbound or both). In the channel handler definition, you can use the structure wrapper APIs provided in the DOE.You have to use transaction SE24 to implement the channel handler definition.

       4.      Assign filters for the channel, if required.

Filters restrict the amount of data that is sent to the channel’s devices.
