Dynamics 365 Business Central: How to get the client type that is running in the current session via AL code

Hi, Readers.
This week, I found an interesting question on Twitter. Although it already had an answer. I’d like to talk a little more about the details.
Question:

So in this post, we will discuss how to get the client type that is running in the current session via AL code.

First let’s take a look at Client Type in Business Central.
ClientType Option Type: Represents the type of the client executing the operation.

Memebers:

Member	Description
Background	A background session.
ChildSession	A child session.
Desktop	A desktop client.
Management	A management client.
NAS	A NAS client.
OData	A NAS client.
Phone	Microsoft Dynamics Business Central Phone client.
SOAP	A SOAP client.
Tablet	Microsoft Dynamics Business Central Tablet client.
Web	Microsoft Dynamics Business Central Web client.
Windows	Microsoft Dynamics Business Central Windows client.
Current	Microsoft Dynamics Business Central Windows client.
Default	The default client.
ODataV4	A ODataV4 client.
Api	An API client.
Teams	Microsoft Teams client.

Then, there is a method.
Session.CurrentClientType Method: Gets the client type that is running in current session.

For example: Show the client type when open Item list page.

Browser:

Phone:

Teams:

Business Central Windows 10 desktop app:

So what can we do more with client type?
Similar to the question at the beginning, we can use this function to specify each client type’s program separately.
For example: Item Description can only be modified in the web client.

If you modify it in other client types, an error will be reported.

Hope this will help.
