current period vs previous period comparison in power bi

to exclude the start of period to calculate twice, I'll move one more day back. He first started working on Analysis Services in 1998, back when Analysis Services was known as OLAP Services. The first step is to create a base measure to calculate Sales Amount: I will straight away create another measure, which will calculate same figures, but shifting one month back: There are multiple different ways to calculate this measure, but I prefer using DATEADD() function since it gives me more flexibility with shifting periods (thats an official excuse:)In reality, Im coming from the SQL world, where DATEADD() is one of the most important functions when working with dates). ), Please provide tax exempt status document, What To Consider When Comparing Current vs. Find out more about the online and in person events happening in March! This will make the entire report dynamic and eliminate the need for a measure for each time range. Under Allowable values, selectRange.5. It is a token of appreciation! ALLSELECTED ( [] [, [, [, ] ] ] ). In the example we use the number of days in the two periods as the allocation factor; the business logic may dictate that only working days should be used for the adjustment. The user selects two different time periods (current, comparison) through slicers. The last chart sets the prior year on the zero axis, showing that while sales underperformed at first, they continued improving and eventually ended the year above target. In our example, if we choose again dates between November 17th and December 17th, instead of showing me values from the previous month (comparing December 17th and November 17th), with YoY comparison I want to compare December 17th 2009 with December 17th 2008! The output is in the screen shot (and also in the PBIX file), although here I have hard coded the report cycle names in the measures to illustrate what I am trying to achieve dynamically. Remarks.

The two time periods might have a different number of days, like comparing one month against a full year. Here is the calculation step by step, I'll start with Start of Previous Period; Start of Previous Period Using DateAdd to reduce number of days from DimDate Power BI Publish to Web Questions Answered. For those differences, Ive created two additional measures: Lower Card is conditionally formatted based on the values, so it goes red when we are performing worse than in the previous period, while it shows green when the outcome is the opposite: Now, thats fine and you saw how we could easily answer the original question. How to organize workspaces in a Power BI environment? However, the variance of the change compared to 2006, for the Graduate Degree is higher than the High School, and that is why Graduate Degree comes earlier in the sorting. In Power BI, we may want to compare periods with our data to create reports such as year over year comparisons. Understanding this fact; now we can answer this question: The first difference is that ParallelPeriod gives you the option to go as many as intervals you want back or forward. same period; means if you are looking at data on the day level, it would be same day last year. In order to enable the choice of two different time periods, the model must contain two date tables: one to select the current period, one to select the comparison period. Let's dive right into the first step. In this example interval is DAY, and date set is all dates in DimDate[FullDateAlternateKey] field (because DateAdd doesnt work with single date), and the number of intervals is Days in This Period multiplied by -1 (to move dates backwards rather than forward). If you need to expand on built-in Quick Measures, there is a whole range of useful Time Intelligence functions. The above multi-year design adds important context, but the design is not without its problems. Anticipating further questions in the dashboard design process can help avoid wasted effort explaining variances that are well within normal ranges or may even contribute to a favorable trend despite being unfavorable at a point in time. by Andy Cotgreave). ; current_vs_previous_period_hidden_advanced will be useful should you want to build . However, if you do not have data after December 25, 2008, you might want to compare only the same range of days (December 1 to 25) in the year-over-year comparison. Even with that, as more years come into in view, it is almost impossible to spot year-over-year trends. and the number of intervals can be negative (to go to past), or positive (to go to the future). You said at the beginning: normally prefer to create an explicit measure for this type of calculations, thats why I have create a measure named This Period Sales . Its not giving me all the dates. DateAdd is a function that adds or subtracts a number of days/months/quarters/years from or to a date field. [Date] for SamePeriodLastYear and DateAdd functions. Here is the solution that I have found to work. Sometimes, you can use a simplified version of the filter for PY Last Day Absolute measure, leveraging on the current day, or the previous day, for example using this approach for the variable CurrentRange: However, if for any reason you do not receive updated data, the dynamic measure extends the range of the comparison in the previous year even if the data available do not have the latest days. Cheers For each report, they get a number grade (called the attainment track). Create a measure with the following dax. You can navigate to periods in the past or future. The Waterfall chart is a good visualization to show you changes on value over a sequence, The sequence can be time, or date or workflow steps, etc. SAMEPERIODLASTYEAR Returns a table that contains a column of dates shifted one year back in time from the dates in the specified dates column, in the current context. SelectedRCy2 = DISTINCT('Masked Report Data'[Report Cycle Name]). Now we can see this has very little to do with impressive sales during the busy season. Here Ill explore the practical implications of variance analysis methods and suggest ways to avoid mishaps.
