Calculated column to assign numeric code to dates
Hi all, thank you for your input but it turns out there was actually a very easy way to do this in Power Query. Steps below:
1. Use the group by function on the date column, setting the operation to "all rows", making a nested table for each date.
2. Add an index column (I used the custom starting point of 99001 and incremented at 1)
3. Expand the nested tables back out.
Each row now has a unique identifier based on its date!
Hello
Use Rankx
Date ID = RANKX( ALL('Table'[Date]), 'Table'[Date], , ASC, Dense )

Thank you for your reply. In trying this I'm getting a 'Token Literal Expected' error after ASC,. I am not sure how to correct this error. A screenshot is included wtih my table names covered up for confidentiality reasons:
You are in Power Query. The solution given to you is in Power BI. so go to Data View, select the table, choose New Column and paste the DAX formula there.
Not in Transform Data / Power Query Editor.
Thank you!
Follow up question: is there a way to add a prefix to these numbers? For example, if I wanted all of them to start with 99.
pankajnamekar25 is there a way to do a similar function in Power Query? I need to use the column to perform an append query afterwards.
