[Lexey]

Colleagues, Daxers need help!
there is a table with the works and cost http://prntscr.com/j5mbxu for each building

There is a planned budget, I do the small analysis on distribution of current costs and I try to impose it on the plan BUT if in the filter I choose one object everything is OK if two

Error Message:

Values of budget = VALUES(Management_Timesheets[Contract amount (EUR)])* [Procentage]

Procentage = [ Honorar]/ CALCULATE([ Honorar]; ALLSELECTED(Management_Timesheets))
