I'm trying to put customers into segments based on their activity in a 4 week cycle. So always looking back at the previous 4 weeks from a given date, and counting the number of activites not only in the 4 week periode but also the number of weeks with activity.
Here is some example data where the "Level" column is the one I wish to populate (and now done manully in Excel to show wanted outcome).
Please provide sanitized sample data that fully covers your issue. I cannot help you without usable sample data. Please paste the data into a table in your post or use one of the file services like OneDrive or Google Drive. I cannot use screenshots of your source data. Please show the expected outcome based on the sample data you provided. Screenshots of the expected outcome are ok.
