Hi, I've 2 rows with a column with 133 and 41 as values, I want to know de median and I use Aggregate object. It gave me back 41 as a result but in fact is 87. Could some one help me about this. Why RM give me back the first value?

regards.

    Are you sure that you have selected the median function and not accidentally used minimum?  I just tried this myself with both TP and with a process and it delivered the mid point between the two numbers in case of even rows like in your example.  See process below for an example.

    Hope this helps,
