Attach Debugger to an Active Session

-

Introduction

Business Central has recently introduced the functionality to attach a debugger to an active User session.

This was previously available in NAV however it has only recently become available for Business Central.

Pre-requisites

Business Central OnCloud/OnPrem

References

Attach AL Debugger - MS Docs

Configuration

To use this functionality, we simply need to create an entry in the launch.json file.



The important properties here are the “sessionId” and the “request”.

This works much faster than the traditional deploy and debug and really makes your life easier as a developer.

 
Also, I tried using it for a Production Environment and as expected it didn’t work. Snapshot debugging it is then!

Conclusion

Thus, we saw how we can attach a debugger to an active user session in Business Central. 

Happy Coding!

Using Notifications in Business Central via AL

Introduction Notifications in Business Central are alerts that appears in the Notification bar based on User actions. Notifications stack up from top to bottom, lasting until the user dismisses them, including those from sub-pages.  Validation errors are prioritized and shown before other notifications. We can use this to alert the user regarding something without taking all the user's notification towards it, in the way messages or errors do. They also have the option to allow Users to make a corrective action by embedding the action button directly into the notification. Let's see how it works. Source Code Pre-requisites Business Central OnPrem/Cloud. References Notification - Business Central Docs Configuration Here, for an example, I've created one simple page which takes two inputs. 1. The message that is to be shown in the notification. 2. The message to be shown after the User clicks on the action embedded in the notification.     And I have two actions which I'l

Plus, it gives users clear messages when something goes wrong, making their experience smoother. It shows that the team has considered the scenario and has measures in place for it indicating a well designed solution.

Configure Gmail SMTP service in Business Central without "Allow Less Secure" setting

 Introduction Business Central has great email features like sending email, editing it with Rich Text, adding attachments, etc, but to send emails, you'll need to connect it with services like Outlook or Gmail. There is no outlook side configuration that is to be done if you are using Microsoft Outlook however if you are using Google's Gmail then there's a litte change that has happened on the configuration end. Starting May, 2022, Google has removed the "Allow Less Secure Apps" settings from the Google Accounts, which was essential is using Gmail to send emails from Business Central. However, to replace that we have "App Passwords" which we can use instead. Also, just something to keep in mind, Google is going to remove this from the "Google Workspace" accounts as well by Sept, 2024 so it would be wise for you to migrate your configurations to use app passwords.
