FSM Calculator v1.0

Details for setting up FSM calculator service

Overview

FSM Calculator is a system that enables FSM Admin to create billing slab for the FSM application(s) with different combination of propertyType , slum , tank capacity and etc..

Generates the Demand after calculating the charges for the given application using the billing slab already configured. This document contains the details about how to setup the fsm-calculator service and description the functionalities it provides.

Pre-requisites

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

Java 8
Kafka server is up and running
egov-persister service is running and has fsm-calculator-persister config path added in it
PSQL server is running and database is created to store FSM Application data
Following services should be up and running:
- egov-perister
- egov-mdms
- fsm
- billing-service

Key Functionalities

FSM Admin an Employee of ULB with FSM Admin role can create, update billing slab(s)
ULB Employee with FSM_CREATOR and FSM_EDITOR can search billing slab(s)
ULB Employee Citizen can file, track and rate the application for cleaning septic tank
ULB Employee can get the estimate for FSM Application
FSM service internally call fsm-calculator to generate a demand

Deployment Details

Deploy the latest version of fsm
Add fsm-calculator-persister.yml file in config folder in git and add that path in persister . (The file path is to be added in environment yaml file in param called persist-yml-path )

Configuration Details

MDMS Configuration

FSM MDMS Configuration is sufficient

Data Setup

Billing Slab Setup

Create Billing Slab with ****a combination of PropertyType refer values form PropertyType Mdms, Slum ( YES/NO), capacityFrom and capacityTo refers to Vehicle Tank Capacity.

Integration

Integration Scope

FSM-calculator will be integrated with FSM Application. FSM Application internally invokes the fsm-calculator service to calculate and generate demand for the charges.

Integration Benefits

Calculation and demand generation logic will be separated from the FSM service. For each implementation, calculation implementation can be changed if required without modifying the fsm service.

Steps to Integration

FSM application to call fsm-calulator/v1/_calculate to calculate and generate the demand for the fsm application
ULB Employee can call fsm-calculator/v1/_estimate to get the estimates for the fsm application
ULB Employee can create billing slab calling fsm-calculator/v1/billingSlab/_create
ULB Employee can update billing slab calling fsm-calculator/v1/billingSlab/_update
ULB Employee can search billing slab calling fsm-calculator/v1/billingSlab/_search
