Configuring Workflows For An Entity

Configure workflows for a new product

Overview

Workflow is defined as a sequence of tasks that has to be performed on an application/Entity to process it. The egov-workflow-v2 is a workflow engine which helps in performing these operations seamlessly using a predefined configuration. We will discuss how to create this configuration for a new product in this document.

Pre-requisites

Before you proceed with the configuration, make sure the following pre-requisites are met -

  • egov-workflow-v2 service is up and running

  • Role action mapping is added for business service APIs

Key Functionalities

  • Create and modify workflow configuration according to the product requirements

  • Configure State level as well BusinessService level SLA to efficiently track the progress of the application

  • Control access to perform actions through configuration

AttributesDescription

tenantId

The tenantId (ULB code) for which the workflow configuration is defined

businessService

The name of the workflow

business

The name of the module which uses this workflow configuration

businessServiceSla

The overall SLA to process the application (in milliseconds)

state

Name of the state

applicationStatus

Status of the application when in the given state

docUploadRequired

Boolean flag representing if document are required to enter the state

isStartState

Boolean flag representing if the state can be used as starting state in workflow

isTerminateState

Boolean flag representing if the state is the leaf node or end state in the workflow configuration. (No Actions can be taken on states with this flag as true)

isStateUpdatable

Boolean flag representing whether data can be updated in the application when taking action on the state

currentState

The current state on which action can be performed

nextState

The resultant state after action is performed

roles

A list containing the roles which can perform the actions

auditDetails

Contains fields to audit edits on the data. (createdTime, createdBy,lastModifiedTIme,lastModifiedby)

Deployment Details

  1. Deploy the latest version of the egov-workflow-v2 service.

  2. Add businessService persister yaml path in persister configuration.

  3. Add role action mapping for BusinessService APIs.

  4. Overwrite the egov.wf.statelevel flag (true for state level and false for tenant level).

Configuration Details

The Workflow configuration has 3 levels of hierarchy:

  • BusinessService

  • State

  • Action

The top-level object is BusinessService which contains fields describing the workflow and a list of States that are part of the workflow. The businessService can be defined at the tenant level like pb.amritsar or at the state level like pb. All objects maintain an audit sub-object which keeps track of who is creating and updating and the time of it.

{
        "tenantId": "pb.amritsar",
        "businessService": "PGR",
        "business": "pgr-services",
        "businessServiceSla": 432000000,
        "states": [...]
    }

Each state object is a valid status for the application. The State object contains information about the state and what actions can be performed on it.

{
        "sla": 36000000,
        "state": "PENDINGFORASSIGNMENT",
        "applicationStatus": "PENDINGFORASSIGNMENT",
        "docUploadRequired": false,
        "isStartState": false,
        "isTerminateState": false,
        "isStateUpdatable": false,
        "actions": [...]
    }

The action object is the last object in the hierarchy, it defines the name of the action and the roles that can perform the action.

      {
          "action": "ASSIGN",
          "roles": [
              "GRO",
              "DGRO"
          ],
          "nextState": "PENDINGATLME",
      }

The workflow should always start from the null state as the service treats new applications as having null as the initial state. eg:

{
                    "sla": null,
                    "state": null,
                    "applicationStatus": null,
                    "docUploadRequired": false,
                    "isStartState": true,
                    "isTerminateState": false,
                    "isStateUpdatable": true,
                    "actions": [
                        {
                            "action": "APPLY",
                            "nextState": "APPLIED",
                            "roles": [
                                "CITIZEN",
                                "CSR"
                            ]
                        }
                    ]
                }

In the action object whatever nextState is defined, the application will be sent to that state. It can be to another forward state or even some backward state from where the application has already passed (generally, such actions are named SENDBACK)

SENDBACKTOCITIZEN is a special keyword for an action name. This action sends back the application to the citizen’s inbox for him to take action. A new State should be created on which Citizen can take action and should be the nextState of this action. While calling this action from the module assignees should be enriched by the module with the UUIDs of the owners of the application
