Let's say I connect to a excel workbook as a data source, and want to show increases/decreases of the data since the last import. Obviously only counting new data, how would I go about that?
For instance:
Store 1 2 tickets
Store 2 4 tickets
Store 3 1 ticket
Store 4 3 tickets
the following week I upload the data and it shows the following in addition to the previous:
Store 1 3 tickets
Store 2 5 tickets
Store 3 1 ticket
Store 4 3 tickets
Store 5 3 tickets
how could I calculate the additional tickets while not counting what was there last week? Such as a % increase?

Hey,
basically this is not possible right now.
Each time you import data, the Power BI dataset does not reflect the change, instead the imported data represents the complete data.
You can cricumvent this issue if you are on Power BI Premium, because Premium provides the of incremetal data refresh (as far as I know sooner or later this feature will also come to the Pro licensing - but there is no date available when this will happen). But you also need date columns to configure what has to be added to the existing dataset.
The most simple way to calculate change, is to either add new date to the same excel sheet with an additional date column that reflects the week in the year. Or create an Excel workbook for each week, make the date a part of the workbook name, This solution will become slower and slower over time as the number of Excel workbooks will grow over time. I use this solution throughout some projects, without an issue.
Hopefully this provides you some ideas,
Regards,
Tom
