MAX date for an ID with repeating dates
Hello,
I would like to get your help in the following matter. I have ID's with multiple dates. I need to return latest date for each of the ID's and compare the result with the specific row. If the result matches, I will use it as a filter, to make my inital table unique which will allow me to use it as a lookup table when I will create relationships later. Example of the problem:
The problem is that I am completely new to so called M language and can't really figure out how to solve this with M formulas/sytanx.
Sorry I was out of office
In Query Editor, you can use Group By Function to get the Max Dates for each ID

You could also use DAX calculated column
Max Date = CALCULATE ( MAX ( Table1[Date Hour and Minutes] ), ALLEXCEPT ( Table1, Table1[Application ID] ) )Thanks Zubair_Muhammad but I thought that it is better to do it in query mode because it is somehow less hardware demanding procedure. Am I wrong on this one?
Also, how can I filter out ture ones in data view so that the table becomes uniqe in relationship view. I did filter out the value but I still couldn't create relationship. See screens attached.
