**Link**

→ {base url}/mgramseva/home/billmanualgenerate.

![](/files/-MkMitzIqpvO15tXQwwX)

* This will be used in cases when the scheduler is not run (due to technical errors) and GP wants to run manually.

### **Default Values Set**

* The service category displays water charges by default
* The service type displays non-metered connection by default

### **User Interaction on Screen**

* Set the billing year from the drop-down which contains the list of financial years.
* Set the Billing cycle which contains billing cycles for the selected financial year.
* On Click of Generate Demand Button, Bulk Demand is generated and the user is navigated to the success screen.

### **Logic Implemented for Billing Cycles**

* The Billing Cycle drop-down shows a list of months starting from the selected financial year **from Date** month till current date month.
* On selection of the desired month, the billing period value is set from the selected month’s first date to the selected month’s last date. (Eg. Selected Billing Cycle: June 2021, so Billing period: 01/07/2021 - 30/07/2021)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.digit.org/public-finance/v2.3/exemplar/mgramseva/user-manual/tech-user-manual/generate-bill.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
