Generic / Unknown Tool
Designer tool icons represent the tool's specific task or macro. When Alteryx Designer can't find a macro referenced in a workflow, Designer displays the Unknown tool along with an error message to let you know. This gives you an opportunity to reconfigure (right-click and choose Insert > Macro to browse to the macro), which restores the intended tool.
The Generic tool, which also displays the question mark icon, is used to access a dynamic-link library (DLL) or plugin.
Note
This tool isn't visible on the Designer tool palette.
