I am migrating the standard "parameter table function" that uses an Excel workbook to instead use a named table. My table is named "Parameters". My function is:
(ParameterName as text) =>
let
ParamRow = Table.SelectRows(Parameters, each ([Name] = ParameterName)),
Value=
if Table.IsEmpty(ParamRow)=true
then null
else Record.Field(ParamRow{0},"Value")
in
Value
But this error is reported:
An error occurred in the ‘’ query. Expression error: The name 'Parameters' wasn't recognized. Make sure it's spelled correctly.
So clearly I don't understand how to reference named tables in Power Query. What am I missing?
Thanks
Solved! Go to Solution.
You should be able to make the reference as you're describing. I would double check for case and extraneous whitespace (trailing spaces are never fun). If these check out, would you be able to share a sample .pbix (hosted publicly on OneDrive or similar) that recreates the issue for us to look at, please?
By "Named Tables" do you mean a table in your Excel workbook? PowerQuery (M language) cannot directly interact with Excel's objects. You need to import the workbook and then operate on the imported Query.
Hi,
I have a query named "Parameters". It is of type "table" (has table icon in query sidebar). It was created with the new "Enter Data" feature.
Thanks,
Chris
It may recognize the query as table in M formula. Try to create another query of the current Parameters table, then name the query to "Parameters".
The parameters table is a query. The query name is "Parameters". It is of type "table"

Ok. I'll make one from scratch and if it still doesn't work I'll post it online.
The one I made from scratch worked fine. So either I had typo or I had used a reserved keyword. Where are the reserved keywords documented?
So this function references an object (table?) called Parameters. Is that loaded in your data model already? I have never used functions in Power BI. I assume they work - not sure.
