Expression Refers to Multiple Columns Error when FILTER put inside Switch

Question

I have a table containing different dates (dateARInitiateComplete,&nbsp; dateARScreenComplete, dateARCloseComplete).&nbsp; These values need to be sent to the filter and then returned in the calculated table as Complete.&nbsp; The code works fine so long as I'm only using one condition (First Example).&nbsp; When I add Switch (Example 2), I get&nbsp; the error message "The expression refers to multiple columns.&nbsp; Multiple columns cannot be converted to a scalar value".&nbsp; &nbsp;I can't figure out how to switch out one column name for another to be able to filter the specific column selected.&nbsp;Example 1 - workingTesttblVarvDateField =VAR vBeg = EDATE ( TODAY(), -1 )VAR vEnd = EOMONTH ( TODAY(), -1 )VAR vSelected = SELECTEDVALUE(lkupWorkFlowSteps[agDescription])var vFilter =&nbsp; &nbsp; &nbsp; FILTER&nbsp; &nbsp; &nbsp; &nbsp; (&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;'tblCR',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;'tblCR'[DateARScreenComplete] &gt;= vBeg &amp;&amp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;'tblCR'[DateARScreenComplete] &lt;= vEnd&nbsp; &nbsp; &nbsp; &nbsp; )&nbsp;RETURN&nbsp;ADDCOLUMNS(&nbsp; &nbsp;SUMMARIZE&nbsp; &nbsp; (&nbsp; &nbsp; &nbsp;vFilter,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;'tblCR'[FSA],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'tblCR'[iCASNumber],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'tblCR'[DateARScreenComplete]&nbsp; &nbsp; ),&nbsp; &nbsp; &nbsp; &nbsp; "Complete", 'tblCR'[DateARScreenComplete])&nbsp;&nbsp;Example 2 - not workingTesttblVarvDateField =VAR vBeg = EDATE ( TODAY(), -1 )VAR vEnd = EOMONTH ( TODAY(), -1 )VAR vSelected = SELECTEDVALUE(lkupWorkFlowSteps[agDescription])var vFilter =SWITCH(&nbsp; &nbsp;TRUE(),&nbsp; &nbsp;vSelected = "AR INITIATE",&nbsp; &nbsp; &nbsp; FILTER&nbsp; &nbsp; &nbsp; &nbsp; (&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;'tblCR',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;'tblCR'[DateARScreenComplete] &gt;= vBeg &amp;&amp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;'tblCR'[DateARScreenComplete] &lt;= vEnd&nbsp; &nbsp; &nbsp; &nbsp; )&nbsp; )RETURN&nbsp;ADDCOLUMNS(&nbsp; &nbsp;SUMMARIZE&nbsp; &nbsp; (&nbsp; &nbsp; &nbsp;vFilter,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;'tblCR'[FSA],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'tblCR'[iCASNumber],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'tblCR'[DateARScreenComplete]&nbsp; &nbsp; ),&nbsp; &nbsp; &nbsp; &nbsp; "Complete", 'tblCR'[DateARScreenComplete])

Hi&nbsp; Anonymous&nbsp;,
&nbsp;
Dax function can include a calculated table in the measure, but Measure outputs a single value, your dax function outputs a table or a whole column of values, so that's why you get that error.
&nbsp;
You can consider using CALCULATETABLE or you can consider using MAXX() similar aggregation function + Filter() function to combine the output of the value you want, you can try to explain what kind of result you want to output in the measure, share sample data and sample output in table format? Or sample pbix after removing sensitive data. We can better understand what the problem is and help you.
