Count ID's bewteen Dates

[Seier-Alsenz]

Hello,

I need your knowledge.

i have a list of employees with start date and end date (and much other master data). i would like to count how many employees i had at each point in time. in some cases i would like to query this differentiated by company or occupational group.

i have the basic question if this is solved in the best-practise in a SET-Analysis or by a script.

Currently this is solved in Excel and have built a large matrix at the monthly basis. It looks something like this solution:

Is a flag table (employees per month) getting too large? Or is this concern irrelevant?

Kind regards

If you have a date calendar already setup you can intervalmatch() to the employee table and then just do a distinct count of employeeID's over the dates that you're after.

Few solutions here would work: https://community.qlik.com/t5/QlikView-App-Dev/Employees-HeadCount/m-p/1311662
