unable to reference a field from a table
- 7 years ago
You cannot reference a "naked" column within a measure. In a measure there is no row context so the engine does not know what row you are referring to. Have a look at this and or this
I would also stick to always using fully qualified names for columns, i.e. TableName[ColumName] instead of just [ColumnName]. The latter is best reserved for referring to measures: [Measure]
Hi JimB-GA
Can you show the code where you get the problem and the error message?
Can you, ideally, share the pbix indicating where the problem is?
Hi, and thanks for reply. I cannot reference a field from one table to another in calculation.
My objective is to create a measure Total_Cost =[Last] (from Current table)-[New Price] (from Transactions
When I attempt to insert Measure =[Last] in the 'Transactions' table, the error reads
"The value for 'last' cannot be determined. Either 'last' doesn't exist or there is no current row for a column named 'last'.
I have inserted link to file Test.PBIX in dropbox to illustrate.

Thanks

Hi JimB-GA
If you want to create a measure,you may use SUM Function as below.Total_Cost=SUM('current'[Last])-SUM(Transactions[New Price]).If it is not your case,please explain more about your expected output.
Measure = SUM('current'[Last])Regards,
