Qliksense - Identifying Repeated Customers between Week N & Week (N-1)

Hi members of the Qlik Community!

I have just joined a tech startup as a business analyst, and while I have no problems performing routine tasks right within Qliksense, I am starting to run into more complex problems, some of which I have little to no clue to go about solving it

For instance, I am trying to generate a list of customers who fulfills the below conditions:

Orders at least once in 2016/10 and at least once in 2016/17 AND

Delivery fails to reach them due to 'Error' at least once in both times

...and I have the following key fields available:

[1] customer_id (e.g. alphanumeric string)

[2] package_id (e.g. alphanumeric string)

[3] delivery_failed_reason (e.g. 'Error', 'Rejected', 'Cancelled', 'N/A')

[4] delivered_date (e.g. 2016/10, 2016/11, 2016/12, ...)

[5] country (e.g. RU, DE, AU, SK)

In my feeble attempt I have tried the following in a straight table:


if(delivered_date = '2016/10' or delivered_date = '2016/11', customer_id)


count (distinct if(wildmatch('*Error*, delivery_failed_reason), package_id))

I then apply a count function to the measure column, which would ideally provide the count of customers fitting conditions & . However numbers dont look right so far..

Any advice would be much appreciated!

Thank you!
