Here is the code needed to display a Plant in a typical R/3 or ECC system. Now of course the code in the method will vary depending on what you are displaying. A classic example of this is a DISPLAY method. The simplest type of method for this purpose is a Public, Instance method with no parameters. So to start we need an additional method in the ABAP Class example we have been creating.

In the last blog I mentioned that you cannot call any method inherited from the IF_WORKFLOW interface directly. In future blogs weвЂ™ll deal with multi-step workflows, but as multi-step workflows essentially organise single-step tasks, single-step tasks are a good place to start when building workflows. In ABAP OO terms, a single-step task calls one method only to perform this piece of work. a piece of work that does one thing only. The simplest type of workflow is a single-step task, i.e. How do I use an ABAP OO method in a Task? All you will need for this exercise is an entity with a key (preferably less than 32 characters in length) and some code to call a display user interface (transaction, function, whatever) for your entity. However if you are not in a suitable system or just donвЂ™t want to use a Plant example for whatever reason, you can use your own business entity. Note: IвЂ™ve based the examples on an ABAP Class representing a Plant as this is a well known business entity in most R/3 and ECC systems. It wonвЂ™t teach you workflow either, but it should give you enough to get going even if youвЂ™ve never touched workflow before. Make sure both the definition and runtime environments are activated, so you can create a task and then test it.ДЄs mentioned in the last blog, this blog wonвЂ™t teach you ABAP OO. If you arenвЂ™t sure if your workflow environment is activated, check transaction SWU3 in your system to quickly view and activate the workflow environment in your system. If you want to try the exercise in this blog in your own system, you will need an ABAP Class with the IF_WORKFLOW interface, and a system/client (SAPNetWeaver 6.20 minimum) with the workflow environment activated. Getting started with ABAP OO for Workflow вЂ¦ using the IF_WORKFLOW interface If you havenвЂ™t read the first two blogs yet, do that now. This blog deals with using a workflow-ready ABAP Class directly in the simplest type of workflow вЂ“ a single-step task.

In the previous blogs of this series, I talked about why we want to use ABAP OO with workflow and how to make an ABAP Class workflow-ready.
