Hello all, I have one column in a list showing all accounts with a prefix on all account numbers of "00000". So each of these account numbers show like this: "00000123456789".
I know in typical SQL, I can use a simple: substring([account_num], 6,9), but is there a way to modify this in Power BI using DAX, or any other solution to this?
Thank you!

Solved! Go to Solution.
Try this in the Query Editor
Actually you want to select Last Characters
@Sean's solution will work for M code.
In DAX, you could create a new column with the following formula:
If all account numbers are the same length:
AcctNum = RIGHT([Account Number],9)
If not:
AcctNum = MID([Account Number,6,LEN([Account Number]) - 5)
You may have to adjust start number and how many characters you are removing from what LEN returns, but general gist is there.

Thank you both for the solution. I ended up creating new column and it's working as needed.
Thanks again for quick reply!

If you want to keep the original column - you can hit Duplicate Column first and then Rename and Transform the duplicate so you have access to both columns for reports.
EDIT: You never actually permanently Transform your original data even if you don't duplicate the Column.
You can go in the Query Settings => Applied Steps and just delete that step!
