How to stop overwriting over files in Azure Blob Storage area

[Data_Alter]

I have an Alteryx app in which it writes a file to an Azure Blob storage area at the end of a certain period using the download tool.

I need the workflow to display an error message if the file already exists.

The workflow changes the name of the file using user inputs, ensuring that a file for a different period will be written as intended. However, users should only be able to write a file for one period once. So need to get rid of overwrite functionality.

Hi @Data_Alter 
Could you let me know if you are using the Azure Data Lake File Output tool to create your outputs to Azure Blob?

Unfortunately, I am experiencing a bug with attaching screenshots on the Community, however under the 'options' tab, there is 'existing file action' - with an option to Abort if the file already exists.

In the case you need an error message to appear, you could utilise a control container (https://help.alteryx.com/20231/designer/control-container-tool) to grab the metadata of the tool and create an error in a Message Tool in the case that the operation is aborted.

Kind Regards,

Owen

Thanks Owen, no we use the standard Download tool to write the data and we are not yet on the latest version of Alteryx.
