    Power BI does not have incremental load at present. This means that if you try to timestamp something at the time of query load, you will get updated values for the timestamp when it is refreshed.

     

    Three options for your reference:

     

    1. Storing and using information from a dynamic data source using PBI desktop

     

    2. Use R script: auto export of data

     

    3. Create a Trigger on source table to insert rows to your DataChangeLog table as soon as the data updated from source table in your database. Colde looks like below:

     

    create trigger triggername On sourcetable

for update

as

insert into destinationtable (column) select column from TriggerTest1

Go

     

    You can vote the idea: Allow for point-in-time snapshots for reports/dataset

I'd like to follow your example for option 3.

 

Can you please show step by step directions for how to add like you would do it using example tables?
