Display last Invoice date only

I am trying to display the last invoice date only for each item in the list below. I have tried variations of the Max function with no luck. Any suggestions on how to show only the last invoice date for each unique item with a null value if there is no last invoice date available? Data table is below:

Use max(date([InvoiceDate])).

Yeah I've had an incredibly similar problem to this that took forever to figure out (fortunately for you I think mine was much more complicated, but still similar). I'm actually pretty busy at the moment (only here because the expression I have calculating is incredibly slow) so I don't know if I can give you the exact answer, but if you look at the links and my possible solution below and you'll probably get it.

You need to say something like:

if([Invoice Date]=max(total <[Item No]> [Invoice Date]),

[Invoice Date]

)

In the links below they needed the aggr function but I don't think you do since you want to put the dimension (item no) anyway. I guess you'll have to do that same thing I put above except replace the last [Invoice Date] with each field (you'll need 5 expressions). I literally spent 3 minutes on this so there's probably a better way, but hopefully this works and is good enough for you.

In response to

Upon further review, 22665 isn't going to show (I don't think) if you do this since the max invoice date is a duplicate. I'm not sure what you want to show in that situation, so I can't really say what I think you should do.

Hi,
I had a similar 'problem' regarding the last Login Date for Users in our System but "Date(Max(LoginDate),"MMYYDD")" worked for me as per below;:
