Introduction
The main objective of the Workflow Engine is to maintain master and transactional data for every state of business entity which undergoes a workflow and provides a history of workflow transition. Any entities in the system can be configured to have a workflow using this engine.
PrerequisitesÂ
The Business entity has to extend the basic workflow entity (StateAware). Since this is a position based workflow engine, the employees and positions need to be configured beforehand.
Functionality
| Parameter | Description |
|---|---|
| Master states | The System allows to configure the workflow entity and define respective workflow transitional states |
| Transition on Workflow entity | The system provides APIs to move a workflow entity with defined workflow transitional states with business validations and rules |
| Workflow History | The system provides APIs to get the workflow entity history, where one can see who all it has gone for approval and at what stage it was rejected and what all are the comments. |
