General Definition of Workflow:
The flow of any work or task, which covers the entire cycle of that task, is called Workflow.Example: If you want to apply the leave then you have to fill leave application and sumit the sameto your mana!er. Then after reviewin! your application your mana!er may approve"re#ect yourleave application. This is called workflow of leave.
$racle %pps Workflow Definition:
Workflow is one of the components of $racle %pps, which automates the flow of work"task. Thatcould e purchase order cycle, order mana!ement cycle etc.
This $racle %pps Workflow works on the followin! & '()s.
*. (ules+. (oles. (outin!&. (eal time
I will discuss each '()
1. (ules: This is related to usiness lo!ic. This rule always refers to the re-uirements of theusiness. It tells what to implement y usin! workflow. In $racle %pps these rules areimplemented y rocedures
+. (oles: (ole means who are mainly involved in the activity. /or example in the aove leaveworkflow, 0eave initiator, 1ana!er are called roles in leave workflow. In oracle %ppsworkflow, '(esponsiilities) playin! as roles.
. (outin!: (outin! represents the actual flow of workflow. It tells us how the workflow is!oin!. In workflow dia!ram, the transition lines represent the routin! of the workflow.
&. (eal Time: This ( represents the (eal time concept in the workflow. 2y usin! workflow wecan control the time also. /or example if the leave approval is pendin! with 1ana!er for days then automatically this workflow escalates to next approval authority. 'Time outfeature) of Workflow implements this concept.
3ow I will discuss the different 4omponents of Workflow:
1. Workflow 2uilder: This is the main component of workflow. 2y usin! this component,developers will develop"customi5e the workflow. 6ou can create new workflow from scratchor you can customi5e already existin! seeded workflow.
+. Workflow En!ine: This component mainly controls the entire workflow activities in $racle%pps.
. Workflow Definition 0oader: This component translates the !raphic components to textformat while savin! this workflow in disk as a file and it !ets saved with .wft extension7Workflow Text8. This loader also translates the .wft format to !raphics format whileopenin! the file in workflow uilder.
&. Workflow 3otification En!ine: This component is responsile to send the notifications to theroles defined in workflow. /or example when employee sumits the leave re-uest,workflow notification en!ine sends the leave information as notification to 1ana!er.

9. Workflow tatus 1onitor: 2y usin! this component, we can see the status of worklowrelated to current transaction.
Overview:
This article will illustrate how to create or define workflow attriutes, notifications, messa!es, roles
or users, functions, processes and last ut not the least, how to launch a workflow from 0";0.The workflow concepts are etter explained usin! an example.
Business Requirement:
When an item is created in inventory, workflowneeds to e launched and it should collect thedetails of the item created and sends a notification to !roup of users alon! with the details and linkto master item form.

WF_(T)WF_-%"#())_$#TIITI()
WF_$#TIITI() table stores the definition of an activity. $ctivities can be -rocesses,
notifications, functions or folders. $ process activity is a modelled wor/flow process,
which can be included as an activity in other processes to represent a subprocess. $
notification activity sends a message to a performer. $ functions activity performs an

automated function that is written as a -0) stored procedure. $ folder activity is not
part of a process, it provides a means of grouping activities.
WF_IT(*) is the runtime table for wor/flow processes. (ach row defines one wor/ item
within the system.
WF_IT(*_$TT%I&'T() table stores definitions of attributes associated with a process.
(ach row includes the se2uence in which the attribute is used as well as the format of the
attribute data.
WF_!"TIFI#$TI"!) holds the runtime information about a specific
instance of a sent message. $ new row is created in the table each time a message is sent.
Process flow:When an item is created it will create"insert a record in MTL_SYSTEM_ITEMS_Bsocreate a databasetri!!er on the tale and launch workflow from that tri!!er. %ll you need to do iscreate the workflow, create the tri!!er, pl"sqlpacka!e, roles and finally create an item in inventory.
