Long Term Measure Suddenly Not Working

[24601]

Hi,

My organization has been using a measure for years without any problem and in the last 4 days there have been issues. 

The measure is a simple count rows of a sales fact table, filtered by a date. USERELATIONSHIP is required to activate the relationship between the fact table and the date table, date & date sold. I noticed that the measure gives incorrect values when I add another measure calculation items sold filtered for specific product. It is possible that other measures also produce and incorrect value. There is only one relationship from the product table and that is to the sales fact table. 

The image shows a breakdown by year. 
Error Sold - Is the broken measure due to the Specific Product
Actual Sold - Is the correct volume of items sold
Actual Purchased - Is a measure similar to sold but uses date purchased as the date relationship. This measure does not break with the inclusion of the Specfic Product measure. 
Specific Product - Calculates items sold for the specific product. 

The Error Sold measure still produces the correct total value but as per above the year on year numbers are not matching. 

Measure for Error Sold:

CALCULATE (

    COUNTROWS ( Sales),

    USERELATIONSHIP ( 'Calendar'[Date], Sales[Date Sold] ),

    FILTER ( Sales, [Date Sold] >= Date ( 2018, 1, 1 ) )

)

As said, this has worked for years and suddendly it is not. I don't know whether there is an issue with the measure or formatting of the measure. There are lots of measures that filter by date and I would not like to have to change them all. 

Any help or advice on what might be the issue here would be massively appreacited. 

Thank you.

Hi  @24601 ,

In your description it is mentioned that: when adding another Sales Volume Value Calculation item for a specific product filter, the metric gives incorrect values. It is possible that this screening context is causing the error.

Measure_ =
CALCULATE (
    COUNTROWS ( Sales ),
    USERELATIONSHIP ( 'Calendar'[Date], Sales[Date Sold] ),
    FILTER (
        ALLEXCEPT ( Sales, Sales[project] ),
        [Date Sold] >= DATE ( 2018, 1, 1 )
    )
)

Futher to the above:

The measure has stopped working in dataset that have been frozen since the end of 2021 and 2022 so no refreshes have taken place or changes made to those datasets since they were frozen.
