Analytical app related queries

[Sangappa]

Hi alteryx team,

I have created an analytical app using superstore data by taking input in .CSV format, my requirement is to append the data every month for  the existing data and calculate the matrix value.

Challenges we are facing is,

1. Only the newly uploaded data should process rather than processing all the appended files everytime.

2.Expecting error message if user try upload already existing file.

3.by choose file name I would like to delete data from end user if they uploaded wrong file.

4.Way to upload multiple files by manual selection

For example - if we have 10 files in a folder I would like to upload 5 out of ten files.how can we achive this.

Have a look at the image of analytical app created.

Ur time support and suggestions are appreciated.

Thank you.

Hey @Sangappa,

I am kind of confused, your Workflow shows a process to update one single file but you talk about multiple files - where are the other files coming from?

Hi,

We are using wildcard (*) at the input for reading  multiple file.but expecting multiple selection from the user end.
