Copy newly added data to fixed column
Hello,
I am trying to use powerbi to read excel data from a task schedule. But I would like to use PowerBI to show the original scheduled dates, even after the schedule gets updated.
So when new data is entered in Start Date and End Date, I want columns to be populated with that data.
But once the Original Dates are populated once, I don't want them to ever change again.
So if the Start Date and End Date are adjusted, I want the Original dates to remain static.
Wednesday's new update: Start and End date updated for Task A, but Original didn't change. Now Task B also has newly added dates.
Then on Friday, Task B's dates are adjusted, but the Original dates don't change.
Is there a Dax operation to do this ?
Thanks

power bi isn't a database as such, you will need to store historic copies of your data if you want retain history.
- there is also incremental refeshes if you have premium https://docs.microsoft.com/en-us/power-bi/admin/service-premium-incremental-refresh which might solve your issue

Basically what I want to do is create a Baseline data column based on the first date entered for a given row.
(Similar to the MS Project Baseline function)
you will have to keep history if you using the same source and overwriting it. Or create a new field for the original date.
