# What-If Manager Widget

## Overview

| Plugin key                   | BAS Setting key                    |
| ---------------------------- | ---------------------------------- |
| `accelerator_whatif-manager` | `bas-plugin-widget-whatif-manager` |

With the What-If Manager you can examine the What-Ifs you created, delete those you no longer want, and view the audit trail of who has done what.

You can even see the difference in the data after the What-If was created.

## 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["widget"]["accelerator_whatif-manager"];
  }
}
```

### 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 `FRTB` server only:

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

 const extension: ExtensionModule = {
  activate: async (configuration: Configuration) => {
    ...
+    const frtbBASSettingsWithFeatureDisabled = produce(frtbBASSettings, draft => {
+      delete draft["FRTB"]["bas-plugin-widget-whatif-manager"];
+    });

-   activateFrtb({configuration});
+   activateFrtb({configuration, basSetttings: frtbBASSettingsWithFeatureDisabled})
    activeMarketRisk({configuration});
  }
}
```
