Power BI Add timestamp for webdata and append data

[powerbihelp87]

My source is a Web URL.  It is updated twice a day with data (historical data is not available, its new data everyday)

Basically what I am looking to do is schedule a Power BI refresh twice a day.  Each time I refresh and new data is added I wanted the a column indicating the date and time. Then later in the data for the second refresh the new data is appended to the first refresh and also indicates the date/time it is added in Power bi

The weblink is only reporting new data but my query in Power BI will be growing and indicating the date/time rows were added in powerbi.  I am not sure if this is possible in PowerBI without other tools!

I'm just resurfacing this one - as I too have the same question.  You'll need to forgive me, as I'm not that good with Power Query, but I would assume you could perhaps do the following logically:

If anyone with knowledge could comment on the approach in general.....

Timestamp Table - Create a very large table (More rows than to expect from the call) with todays date / time

Landed Data Table - Do the Web Call to a new table

Merge / Append the "TimeStamp" Table, to the "Landed Call Table

Trim the resultant Merged Landed Table

Merge / Append to existing table.

Hi @powerbihelp87 ,

I think it's possible to show you the last refresh time in power bi , please kindly refer: 

Show it in the tile: https://community.powerbi.com/t5/Desktop/Automatically-adding-date-for-last-refresh-of-data/td-p/751...

Show it using query editor: https://www.excelguru.ca/blog/2016/06/08/display-last-refreshed-date-in-power-bi/

But based on research, it's not accessible to indicate the data added.

Thank you for responding! I have been searching and do not see a way to add when each specific row was added into Power BI. 

I know there is a way to show the most recent date but the user is looking to spot what time each row is added.
