Hi All,

When we say something about the Sandbox framework from D365 FinOps developer's perspective, does this have something to do with SysOperationSandBox or completely something else?

When do we need to use this framework and please provide me with any sample code or any open source which implements this framework.

Thank you.

Hi ShawnDEV,

I have not heard of a 'Sandbox framework', but I'm aware of the SysOperationSandbox. This class has replaced the RunBaseBatch classes which were available in AX2012.

You can read about this class on the next blog: devblog.sertanyaman.com/.../

Hi ShawnDev,

I would say SysOperationSandBox is a part of "Sandbox framework" (it's mentioned only in Dev exam, but there is no other documentation on it).

SysOperationSandBox allows you to run long processing in a separate session in async mode and shows the waiting form for async process (UI us not locked). Also, it provides "Cancel" button for this kind of process.

You can use it:

1. Directly from code - let's assume you need to run some long-running process and you already have a static method for it or you are planning to write it, but you don't want to create runBaseBatch or SysOperation class for operation. In this case, you can utilize SysOperationSandBox if you don't want to leave the user with a "freezed" UI.

2. You can use it in RunBase and SysOperation by returning true in method canRunInNewSession (note that for RunBase you need to use runOperation method instead of run in main method, but there is already BP practice warning in place). You should also take into account that in this case, you need to implement pack\unpack design pattern, as the async session will be created based on packed variables.

Hi,

When we implement SysOperationSandbox framework class, it is indeed showing the progress bar to show the progress to the user. However, a user is not allowed to do other actions as the UI is frozen until the operation is finished. Is this because this operation is running synchronously so that other actions are not allowed to perform?

Thank you

Hi ShawnDev,

From the user perspective, UI as still blocked, but the user can cancel the request.

From a server perspective, new async process is created to avoid blocking of UI process.

Hi Sergei,

I actually meant other operations like opening other forms, creating a record while running the operation having SysOperationSandBox framework. I somehow understand the concept of Async process in that it excutes a task in the background without the user having to wait until the operation is finished. But apparently users have to wait if they want to perform other operations. Could you correct my thought?

Thank you.

Hi ShawnDev,

If you use SysOperationSandbox users need to wait until the operation will be finished.

If you want to run async process (as real async), you need to check ReliableAsynchronous option for SysOperation framework or runAsync method.

In general it's considered best practice to submit long running processes to the batch.

If a user runs the job "interactively" there is a timeout on the client(browser scripts) where it calls the server process and waits for a completion/response. This will time out. Sandboxing is meant to keep that connection alive while the user waits for completion, without the browser/request timing out.
