I am sending you snapshots in which Customer_ID is primary key and still showing frequencies...but in some examples we can not apply show Frequencies for primary key... because it is desabled... i dont understand why this is happening?
i sorry i don't speak english very but i want to gives my view. It is not possible to use the function count on Primary Key in Qlikview. You can use count on another field of a table but not on the Primary Key, do not forget it.
As per reference manual version 10 page no. (book 1 pg 472) (you can search using 'Frequencies'),
it is written that count function can not be used on the key fields (associating fields). While, I have seen that in some scenrios it works, so it is basically based on the ambiguity if it exists then this function will not work or else it works.
But, showing frequencies, I have never seen to work on key fields.
