Simple Calculations in a measure are not calculating properly 20-5=10

[jleglen]

I have a time worked report. On some of the lines, the report does not calculate the Net Hours properly:

The measure is very simple: 

Daily Hours minus Lunch Time in Hours =

SUM('Time Input Merge'[Daily Hours]) - SUM('Lunch Break Table'[Lunch Time in Hours])

Any thoughts would be appreciated.

Hi @jleglen ,

According to your description, here are my steps you can follow as a solution.

(1) This is my test data.  

(2) We can create a measure. 

Measure = SELECTEDVALUE('Time Input Merge'[Daily Hours])-SELECTEDVALUE('Lunch Break Table'[Lunch Time in Hours])

(3) Then the result is as follows.

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.

Thank you very much. This did correct the problem. Just one follwup question. I lose the totals on the Measure in all of the visuals. The format is fixed decimal. Any ideas?

Thanks again!
