Coding the View-Controller Files

You perform this procedure as a prerequisite to creating an extension in SAP Asset Strategy and Performance Management.

Procedure

Create a UI5 view for the extension.
To create a UI5 controller, follow these substeps:
1. Use the same name in the controller as you specified in the view file.
2. Ensure that the controller inherits an ExtensionBaseController. You can achieve this by following this example:
  Sample Code
```
sap.ui.define([
	"sap/iot/ain/lib/reusable/view/ExtensionBaseController"
], function(Controller) {
	"use strict";

	return Controller.extend("myCompany.equipment.customSection", {});
});
```
  This enables your controller to access the following using controller instance variables:
  - The Object Page Controller (this._oParentController)
  - The Router of the application (this._oRouter)
  - The Event Bus (this._oEventBus)
  - The Object Page (this._ oObjectPage)
  - Application Component (this. _oComponent)
Note
- When initializing the controller, you can use the _initSection method if necessary.
- To refresh the section and fetch data each time, use the function fnRenderSection.
- Both methods _initSection and fnRenderSection have an object parameter containing the ID and the version of the model or equipment.
Sample Code
You can add event handlers and other required methods as per standards and conventions of UI5/openUI5.{ id:32-char Id, status: statusCode //("1" - Unpublished, "2" - Published, "3" - In revision), version: versionNumber }
To ensure that the added functionality works fine, wrap each function in a try-catch block. An example is shown here:
Sample Code
```
onAddButtonClick: function(){
	try{
	//Function Execution Statements
}catch(err){
	this.oView.destroy();
}
}
```

Make service calls in your custom sections through the AIN services. Use the following method to make the service call:

Sample Code

URL: “/ain/rest/testCall”
Type: “PUT”,
Payload: {
	“url”:”YOUR URL”,
	“payload”:{YOUR PAYLOAD, if any},
	“type”:”GET/PUT/POST”,
	“headers”:”REQUEST HEADERS, if any”
}

Results

You have the coded View-Controller files.
