Example
In this example, we are passing the required parameter to the function transformation object using a Variables object. We will be checking for an existing file.
Where,
filePath = C:\Users\Kanwal.Azim\OneDrive - Astera Software\Desktop\Functions Documentation\Files\File Exists\FileExists.docx
Right-click on the function transformation object and select Preview Output. As you can see, Astera Data Stack has returned the Boolean value “True”, as this file does exist.
