I have a sample model from AdventureWorksDW source which includes two tables: DimCustomer, and FactInternetSales, and the two tables are connected using the CustomerKey; Lets say using the waterfall chart, I do have the analysis of SalesAmount (from the FactInternetSales) table by the OrderDate (from the FactInternetSales); This simply shows me the sales amount in each year and the total after the last year in the dataset. If filter context is in DAY level; it will return the same DAY last year, if the filter context is in Month level, it will return same Month last year. to exclude the start of period to calculate twice, I'll move one more day back. The sales of the comparison period must be adjusted using the number of days in each period as the allocation factor. Make sure that there is only one Active relationship between these two tables based on OrderDateKey in the FactInternetSales table and DateKey in the DimDate table.

Cheers What Is the XMLA Endpoint for Power BI and Why Should I Care?

This is an example of using ParallelPeriod: For every month, the ParallelPeriod expression will return a month before that, because in the parameters, we mentioned the month before: ParallelPeriod can be used to fetch the Sales of last month like this: As you can see in the above screenshot; ParallelPeriod will return sales of the entire last month, even if you are looking at the day level.
