Which functionality is not supported with apps published to the Server?

The answer highlights a functionality that is not available for apps when they are published to the Server. Specifically, the Save As dialog window is a feature that allows users to save a copy of their workflow or data files to a specified location. However, when a workflow is published as an app on the Alteryx Server, this interactive dialog is not supported, as server environments are generally designed to execute workflows without user intervention or direct interaction with file system dialogs, ensuring seamless processing.

In contrast, the other functionalities mentioned can be utilized when apps are published to the Server. Running macros is supported because apps can include embedded or referenced macros that perform additional data processing. Accessing input data sources is also permitted, as apps can connect to various data sources defined in the app settings. Adding comments to workflows is achievable because comments are part of workflow documentation and can be included in the published version for clarity.

Understanding these limitations allows users to design their workflows and apps with the server environment in mind, ensuring they leverage supported features effectively while accepting the constraints present in a server deployment.
