DATEDIFF

[Anonymous]

Hi everybody,

I have a dataset where I want to compute the ageing of some items to date.

Basically what I want to do is very easy, it's a subtraction of the item date and TODAY() function. 

I tried to do it creating a measure using DATEDIFF, however when I use this function I cannot select the column field containing the item dates after the parenthesis.

Why I cannot use it as a measure? Should I then go to the query editor? If yes, what's the formula to use instead of DATEDIFF?

Thanks in advance.

Hi @Anonymous

Have you tried using the DATEDIFF function in a calculated column, rather than in a calculated measure?

Do you hve a small sample set of data?

Hi @Phil_Seamark,

it worked perfectly. Could you please tell me what's the difference between a measure and a calculated column?

Thanks in advance.

Cheers,
