Hello, @mohamed.ruzli.moham ,

"Activity Frequeny" counts the total number of times an activity has been conducted. So, if an activity occurs multiple times for the same case, the Activity Frequency takes it into account. Therefore, the general rule is:

Activity Frequency ≥ Case Frequency

What seems to be happening in your situation (at least in the variant depicted) is that your activities are never repeated, which is why you get the particular case where Activity Frequency = Case Frequency.

I hope this helps,
