PowerBI Service showing different values to Desktop

[transform99]

I'm experiencing an odd issue in powerBI Service where published reports are showing different values to PowerBI Desktop.

I have a Project table that has a number of key milestone dates in it (Project start, stage 1, stage 2, Complete). The data is all in a singular table and is not normalised therefore I'm utilising the USERELATIONSHIP function to count records during a given month to show throughput.

There's a significant number of dates that have inactive relationships to a calendar table so that I can flex between relationships without having to split out every single table as shown below.

The formula is straight forward for counting projects during this period using a measure

Monthly Completions = 
CALCULATE (
    COUNTROWS ( fact_Projects ),
    USERELATIONSHIP ( fact_Projects[Completions], dim_Calendar[Date] )
)

I am then placing these measures onto a line graph for comparison against eachother so we can see incoming volume and completed work to measure contrast what's being completed versus what's coming in.

The data being used to show what's coming in is the active relationship (project start date), and I am placing the [Monthly Completions] measure on as a secondary line.

My issue is that in PowerBI Desktop I am getting completely different values to PowerBI Service once a refresh occurs. It's not a case of 1 or 2 either. Each month differs (it's like i'm publishing 2 completely different datasets).

Can anyone provide any input into what could be causing this so that I can troubleshoot and try to rectify?

Hi @transform99 

As you may also agree, such things usually not possible, if it is happening, most likely it is due to changes in underlying dataset view, either due to some filter working or real change in dataset etc

It's kind of troubleshooting and bit difficult to suggest until we see it. So suggest you to dig the difference yourself else post a sample file for us to check. Pls remove any sensitive data.

Hope it helps.

I'm working with my IT team at the moment as I think I narrowed down the issue. The date fields, when extracted, are timestamped as 12AM even though they are date only in powerBI.

The PowerBI Service Server location is 1.5 hours behind my local time and I believe when i'm publishing to server and it refreshes the server is taking values from the 1st day of the month and grouping them into the month before (happening for all months).

I will provide an update once my IT team comes back to me to confirm if this is the issue.
