Definition

The dispatcher ID represents a dispatcher class that is responsible for delegating the execution of requests at the process layer.

The originating design pattern is the interceptor pattern; in this application it has been simplified so that the dispatcher class comprises a hard-coded sequence of interceptors to call, and any variability can be introduced by deriving a subclass and redefining the relevant execution method.

Use

The definition of new dispatchers is only needed if any variance from the standard chain of execution is necessary;
the definition takes place at table CLB2C_IC_DISP.

Dependencies

Note that the authentication step has some internal varaibility by eveluating the authenticaion method and deriving the relevant implementation of BAdI CLB2_AUTHENTICATE.

Example

The default implementation class CL_CLB2_DISPATCHER comprises the following steps:

  • Prepare the connection
  • Authenticate
  • Prepare the call
  • Before the call
  • Call
  • Set / evaluate the result
  • After the call
  • Close the connection
