# Formula Configuration

## Overview

The **Formula Configuration** screen allows you to define and manage resource estimation formulas based on campaign assumptions and distribution strategies. These formulas determine how resources are calculated and whether results appear on the **Estimation Dashboard (Population Inbox Screen)**.

## Steps

### Step 1: Review Autofilled Formulas

**MDMS Integration for Autofilled Configurations**

* The formulas on the **Formula Configuration Screen** are dynamically autofilled based on data from the  [MDMS](https://unified-qa.digit.org/workbench-ui/employee/workbench/mdms-search-v2?moduleName=hcm-microplanning\&masterName=AutoFilledRuleConfigurations).
* These configurations are tailored using specific keys that define the **campaign type, distribution strategies, and processes**.

These predefined formulas can be reviewed, edited (if permitted), deleted, or supplemented with new formulas.

### Step 2: Add a New Formula

To create a new formula:

1. Click **Add Formula**.
2. Enter the **Formula Name**.
3. Select the required **Input Parameters** (assumptions or derived values).
4. Choose the appropriate **Operator** (for example: divide, multiply).
5. Save the formula.

After saving, decide whether the formula should be visible on the Estimation Dashboard (see Step 4).

### Step 3: Delete an Existing Formula

To remove a formula:

1. Click **Delete** next to the formula.
2. If the formula is currently being used in the campaign:
   * The system prompts you to either:
     * Reuse the deleted formula, or
     * Define a replacement formula.

This ensures campaign estimations remain valid and consistent.

### Step 4: Control Dashboard Visibility

Each formula includes a **Show on Estimation Dashboard** option.

* ✔ **Checked** → The formula result appears on the Estimation Dashboard (Population Inbox Screen).
* ✖ **Unchecked** → The formula remains active for internal calculations but will not be displayed on the dashboard.

This allows you to control which outputs are visible to operational users.

### Sample Formula Configurations

Below are examples of how formulas may be configured.

#### Example 1: Total Number of Bednets per Boundary

**Formula:**

```
Total Number of Bednets = Target Population ÷ Number of Persons per Bednet
```

**Dependencies:**

* Target Population (assumption)
* Number of Persons per Bednet (assumption)

**Optional Action:**

* Select **Show on Estimation Dashboard** if the result should be visible to users.

***

#### Example 2: Total Number of Bales per Boundary

**Formula:**

```
Total Number of Bales = Total Number of Bednets ÷ Number of Bednets per Bale
```

**Dependencies:**

* Total Number of Bednets (derived formula)
* Number of Bednets per Bale (assumption)

**Optional Actions:**

* Display it on the Estimation Dashboard, or
* Delete it if not required.

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/health/v2.0/deploy/configuration/microplan-service-configuration/microplan-web-service-configuration/setup-microplan/formula-configuration.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.
