In an OutSystems Reactive Application, we can use Client variables.

Client variables are used to store basic data types in reactive applications (they are also used in mobile applications). You can find more information in the Outsystems documentation.

Sometimes in an Outsystems Application, you just want to show the one record on a screen without editing it.

Service Studio does different things depending on what you drag-and-drop and into where. For example, if you want to create a table in a screen, you drag an aggregate into that screen. Doing this will create a table with the records from that aggregate. If you want to create a form in a screen, you drag first the form tool into the screen and then an aggregate inside the form.

Sometimes you want to give users permission to access the logs of the OutSystems Lifetime machine without giving him the Administrator role.

You are the administrator of your infrastructure. And you want to give a user access to check the logs of the lifetime machine.

But, to do this, you have to give him the Administrator role in LifeTime.

Did you have wonder which web services Service Center of OutSystems exposes? Let's look into it.

Service Center is not a regular module. It's a System Components module and the first module to be installed in your environment. Actually, you need it to be installed before installing the System Components solution.

But the thing is, if you search for it in the list of modules in Service Center, it will not show up.
