Hi all, I am new to FM and new here.. learning as I go, so far so good.. though I am stuck on one calculation.

My question is how to write this calculation when one of the fields included in the calculation is empty.

I am trying to accomplish a calculation of "days held" for assets that we purchase and then resell.

Take the lesser of CurrentDate or DateSold, and subtract the Purchase Date.

If DateSold is empty, then CurrentDate - Purchase Date.

The result is the number of Days Held.

I think I have to use Case but I am not sure. Here is what I have:

Case (

IsEmpty ( Date_Sold ) ; Get ( CurrentDate );

If ( Date_Sold < Get ( CurrentDate ); Date_Sold - Date_Purchased; Get ( CurrentDate ) - Date_Purchased )

)

Am I at all on the right path here? any help appreciated. Thank you.

One way:

Date_Sold - case( isEmpty( Date_Purchased); Get ( CurrentDate ) ; Date_Purchased )

And another way ...

Date_Sold - Min ( Date_Purchased ; Get ( CurrentDate ) )

... be sure this number calculation is set to 'do not store...' in Storage Options

Wait a minute ... I just looked at Bruce' calculation but that doesn't seem like what you want. Try instead:

Min ( Date_Sold ; Get ( CurrentDate ) - Date_Purchased )

... the item was purchased before it was sold. You want the days duration (up through the current date) if not yet sold; otherwise use sale date.

You're right!

Thanks! this works great, I had to adjust the position of the parentheses a bit - below is the final formula I used. Many thanks for your help!
