# Supported What-If Table Context Menu

## Overview

| Plugin key                             | BAS Setting key                          |
| -------------------------------------- | ---------------------------------------- |
| `accelerator_plugin-supported-what-if` | `bas-plugin-menu-item-supported-what-if` |

This plugin allows you to perform a what-if simulation to display instant recalculations and incremental impact on a given measure for a predefined set of levels. To use this feature, right-click on a measure and select the **What-If** option from the context menu. The options you can select are determined by the configuration on the server. This will open a dialog box where you can enter your inputs to execute the simulation.

## How to disable it

### Disable universally

To disable this feature for all solutions, add this line at the end of your extension’s `activate` function to unregister the plugin:

```diff theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
const extension: ExtensionModule = {
  activate: async (configuration: Configuration) => {
    ...
+    delete configuration.pluginRegistry["menu-item"]["accelerator_plugin-supported-what-if"];
+    Object.values(configuration.pluginRegistry["widget"]).forEach(widgetPlugin => {
+        widgetPlugin.contextMenuItems = widgetPlugin.contextMenuItems.filter( menuItem => menuItem.key !== "accelerator_plugin-supported-what-if")
+    })
  }
}
```

### Disable for specific servers

To disable this feature for a given server, you must delete this feature’s settings for that server key by altering the `basSettings` parameter before calling the `activate` function.

**Example**
Disabling this feature for the `MR` server only:

```diff theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
+ import {produce} from "immer";
- import {activate as activateMr} from "@activeviam/mr-sdk";
+ import {activate as activateMr, basSettings as mrBASSettings} from "@activeviam/mr-sdk";
 import {activate as activateFrtb} from "@activeviam/frtb-sdk";

 const extension: ExtensionModule = {
  activate: async (configuration: Configuration) => {
    ...
+    const mrBASSettingsWithFeatureDisabled = produce(mrBASSettings, draft => {
+      delete draft["MR"]["bas-plugin-menu-item-supported-what-if"];
+    });

-   activateMr({configuration});
+   activateMr({configuration, basSetttings: mrBASSettingsWithFeatureDisabled})
    activateFrtb({configuration});
  }
}
```
