Creating a State Manager 

Purpose

Normally, you do not need your own state manager – you can skip this section if that is the case.

Process Flow

Creating a State Manager

If you need your own state manager, follow the steps below.

...

      1.      Name your state manager, for example, MY_STATE_MANAGER.

      2.      Using transaction SE24 create a Usual ABAP Class with the name CL_MY_STATE_MANAGER.

      3.      On the Interfaces tab specify the interface IF_COM_IOITF_SMA.

      4.      On the Methods tab choose the method IF_COM_IOITF_SMA~DETERMINE_TRANSITION; and add the necessary code.

      5.      Save and activate your entry.

Given the application context, this method returns a transition object (conforming to the transition, CL_COM_IOITF_TR, specified by IOITF). The following template could be used.

 

METHOD if_com_ioitf_sma~determine_transition.

 

* Before you can access the Application Context you must convert it

* into the format that you specified for the corresponding Event.

  DATA: lo_my_appl_ctx TYPE REF TO cl_my_appl_ctx VALUE IS INITIAL.

  lo_my_appl_ctx ?= io_appl_context.

 

* --> Begin: Put your code

 

* You can access the information in Application Context as follows -

* lv_iobj_guid = lo_my_appl_ctx->iobj_guid.

* ...and so on!

 

* --> End: Put your code

 

* Create your own Transition

  DATA: lo_my_transition TYPE REF TO cl_my_transition

                         VALUE IS INITIAL.

  CREATE OBJECT lo_my_transition

    EXPORTING

      iv_av = lv_action

 

* Return Transition

  ro_tr ?= lo_my_transition.

 

ENDMETHOD.

 

Registering a State Manager

Once you have created your own state manager, it must be registered with IOITF as follows:

...

      1.      From the SAP IMG, choose Customer Relationship Management à Master Data ® Products à Individual Objects à Individual Object Integration Framework (IOITF) à State Manager à Register State Manager

      2.      Enter the state manager name, description, and class.

      3.      Save your entry.

 

See the example below:
