I am back again with more help with fundamentally trying to understand how Qlik Sense works
I work in a hosted environment and only have access to the frontend no ability to load additional data or add flags.
What I am trying to do: Grab the First Person and Date Combination and Compare it to the Same person with a different date.
Sample Data
Person Identifier Service Date Type of Service
Person A 1/1/21 Admission
Person B 1/7/21 Admission
Person A 1/22/21 Admission
Person A 1/27/21 Primary Care Visit
Person B 2/14/21 Emergency Visit
Person A 2/7/21 Admission
Person B 2/14/21 Admission
SQL would look something like:
select Person_Identfier, service_date, type_of_service from claims a, (select distinct person_identifier, min(service_date) as min_service_date from claims where type_of_service='Admission') b
where a.person_identifier=b.person_identifier and a.service_date between b.min_service_date and b.min_service_date+30 and a.type_of_service='Admission'
Expected Results:
Person A 1/1/21 Admission
Person A 1/22/21 Admission
Person B 1/7/21 Admission
How do I get Qlik Sense to Grab a Person and that Person's minimum (or maximum date) then use that as the selection criteria for all People and Date combinations
