Whatare advantages of SAP Business Workflows?

A business process can consist of several steps. Historically, the

tasks have been coordinated manually or by s ome informal means

of communication (stickynote, e-mail, shouting, and so on).

The common problem in these approaches is :

Inefficiency

Each lacks a w ay to trace w here a task is

Who executed(or is executing it),

How much time it requires.

In contrast, the workflow ensures that the right w ork is sent to the right person at the right time in the right sequence w ith the right information.

Workflow is a tool for automization of business processes

Not tied up to any particular application

Operates uniformly across applications

Coordinate all participating tasks

Provide users w ith active support

Deadline Management is possible

Workflows are very usef ul for business processes that:

Contain a sequence of ac tivities.

Reoccur in the same or s imilar forms.

Involve several people or groups of people.

Require c onsiderable coordination.

What are the layers in Workflow Architecture?

There are 3 layers in the Workflow A rchitecture:

Business Object

Business Process

Organization Model

How Process, Business Logic and People are linked in Workflows?

The business processes are defined in Workflow builder. Each and every small w ork process is called as an activity in the workflow builder. Each activity consists of a single step task, w hich can be a

standard task or a workflow template.

Assoc iated Business Logic is built in Business Objects. i.e. ABAP code will be in Business Object. Business Objects consist of attributes, methods and events. Methods consist of A BAP code. Each and

every s tandard task is associated w ith a Business Object and a method.

People / Group of people responsible for taking actions are defined in organization struc ture. Person responsible for taking an action is called actual agent. It is defined in the workflow activity.

back to top

What is a Business Object?

Business object (BO) is bas ically collection of A ttributes, Methods and Events for a particular business entity. Example of BO: Sale Order, Vendor, Customer, Material etc.

BOs w rap around backend tables, application code, change document and other technical information and expose them as Attributes, Methods and Events. Usually methods of BOs ref er to BAPIs.

The follow ing diagram explains BO much better:

What is an Agent and what are diffe rent types of Agent?

An agent is a person or a group of persons w ho can take an action during w orkflow runtime. Action can be approval of some business document, creation of some document or sending email.

There are basically three types of Agents:

Actual Agent: One w ho actually takes the action. This is provided in the workflow Activity.

Possible Agent: All poss ible persons/entities that can execute a task during runtime. Defines either in Org Structure or task.

Excluded Agents: Persons w ho are excluded from taking action on a task. These are ass igned in the w orkflow definition at the w orkflow activity.

System checks Actual Agent def ined in workflow runtime w ith the Possible Agents def ined in the task and the Excluded Agents. A ctual Agent should be a subset of Possible Agents minus the Excluded

Agents, else Agent resolution fails.

What are the capabilities of Workflow Builder?

back to top

What are Events?

Events are actions that occur in the system and that acts as trigger point for any w orkflow . Eg. Sales order creation. is an event.

Eg; Consider a scenario w here any sales order after c reation subject to approval from superior. So here a w orkflow comes into play. The workflow needs to start w henever a Sales order is created. The

business object BUS2032 is assoc iated to sales order creation. It has event CREATED. So the trigger point or " START EVENTS " in the w orkf low is the BUS2032 's event CREATED.

Then bind the event to the workflow so the data flow s fr om event to the Workflow. e.g.: Sales order is created. So for the w orkflow to proceed it'll need sales order details. With binding the respective

values is mapped ito the workflow container.

Then activate the linkage once you are through the w orkflow creation. This is important as after this only the workflow w ill listen for the event, in the sense that after this only the w orkflow is triggered on

the event. This is critical also as each ac tive link adds to sy stem load considerably and too many w orkflow s in the test environment can bring the sys tem down. So caref ul. Deactivate once test is over and

w orkflow is no longer used.

back to top

What are the various methos of creating Events?

The various metods of creating Events are:-

- Function module - event creation by calling function module

SWE_EVENT_CREATE or SAP_WAPI_CREATE_EVENT.

- Change documents

- Event creation w hen change documents are w ritten.

- General status management

- Logistics Information System (LIS)

- Event creation upon status changes.

- Business Transaction Events

- Message Control

back to top

How can an Event be linked with a Workflow ?

Consider the start of any w orkflow . The START EVENTS tab is taken through the header. The Business Object is specified and binding is generated to the w orkflow to receive the values and then the link is

activated.See the pic below f or the Sales Order creation as start event for a w orkflow .

What are containers, Binding and Binding Editor?

Containers are nothing but the Variables in the Workflow that hold the values in the w orkflow . They can be simple variables or structures or even objects of any class. So they are best treated as the

variables. Binding as explained above is pass ing the values from events, methods and other externals sources to the container. When an event is binded to the workflow then the data automatically flow s

from the Event to the Container in the w orkflow . Binding editor is there as automatic binding may not alw ays pick up the right or des ired binding or precisely the mapping generated may not be appropriate or

as required due to technical reasons w hich any techie can guess. So editor gives an option to the developer to edit or generate manually.

Exception in binding of Task and the Me thod?

It is observed that when w e bind a Task w ith any BO Method then all the fields defined for binding are wiped out after w e save the binding i.e. if w e w ant to see the fields taking part in binding of the TASK

& METHOD or w hile binding the w ork flow and the TASK it is observed that the container elements and task container elements disappear even though binding is established. This happens because of

inconsistent buffer synchronization.

To overcome this issue f ollow the steps in SWDD.

Menu->Extras->Transport->Synchronize runtime buf fer, or go to TCODE SWU_OBUF of buff er synchronization.
