Multiple Input files - Missing file from folder

Vishwak

Hi Team,

As per the process I am considering  multiple input files from the folder while building the tool.

Some times few input files are wont available in the folder, 

1) How can i designed and run  the tool without error - even when few files wont available in the folder.
2) is there any way to place  standing instruction in the workflow?  i mean Alteryx remind/intimate  us that ...hay this file missing in the input folder ?

Please guide me on this, Thanks.

You can create a chained app, where the first app uses a Directory tool to bring in the files, a Count Records tool to count the number of records in the list of files, then a Test tool to determine if there are records. If there are no files in the folder, your app fails. If there are files in the folder, then the second app runs.

If you don't want your app to fail, then you can use a File Browse interface tool at the beginning of your workflow to give the user the ability to select the input file from the folder. If it's not there, then they don't have to run the app.
