The business requirement is to have an expression that calculates the average number of calls per day and employee (no problem) but with the following condition : a day must only be counted if the number of calls is strictly superior to 10.
So the 2nd and 6th line of the table should be "ignored", giving us an average of :
(19+13)/2 = 16 for John
(21+15+11)/3 = 15.7 for Jane
Do you think that this is possible to calculate in an expression, so that the data model doesn't need to be changed ? I have made some tests with the aggr() function but I can't get the correct results...
Thank you for your help, don't hesitate to ask if you need more details about my issue.
