Query Parameter not updating form Query List

[JSiebrecht]

My parameter with Query as suggested values does not update from the underlying list.

I have a parameter "EndpointURL" I want to use in flexibly defining which data source to use for my main queries.

It is supposed to take the value from the query "qEndpointURL" which returns a single value from a LIST (not table oviously).

The value in that list (from query qEndpointULR) in turn depends on the value of a List Parameter ("Environment").
It changes its value correctly depending on the its input parameter.

However, the Query Parameter (EndpointURL) does not update with the changed value from the list if I change the overarching input parameter ("Environment").
It is set to "Include in report refresh", but it does not. 
It always stays on the "Current Value" set initially.

Does anyone know how to get query based parameters to refresh with the values of their underlying queries?

Many thanks!

Cheers,

Jan

(I checked "Enable load" as well for easier trouble shooting so I can easier show the current parameter value in the report.)

I just ran into this.  Basically you want a "parameter" (little p), not a "Parameter". Avoid using the Parameters menu altogether. I take it that is for suggesting values to change manually at some point on the service, not being truly dynamic and automatic.

Instead take your query that creates the "parameter" and right click the value and hit drill down. This will give you a dynamic value that will update on refresh.

You can reference this in a formula step elsewhere or in the advanced editor without first hitting manage parameters. 

In my case I had a date table and I wanted a start date and and end date dynamic parameter to filter the date table, which would be different everyday.

And then I just apply a filter on my DimDate table using that (and a 2nd parameter I made):

= Table.SelectRows(DimDate1, each [Cal_Date_DT] >= WoWDate and [Cal_Date_DT] <= LastBusDate)

Try drilling down on that parameter value in the table (right-click on the value, then select Drill Down. As it stands, You have a list containing a text value, but your query should resolve to a scalar text value. If you just drill down on the list so that you have just the value, the parameter should work.

Dear Nate ( @watkinnc ),

thanks for your input.
However, Query Parameters require a a List Query, not a list drilled down to a single value.
When doing the later, it query is not availbale anymore in the Manage Parameter, Query selection.
Any previously associated queries get cut.

I'm afraid, this does not do the trick.

Additional Finding

I learnt, you should be able to create a new parameter from a query also by right-click on the query and selecting "Convert to Parameter".
I my case, this is greyed out and not available.
Can't figure out why thought.
I have the Dynamic Parameter option checked in the preview menue.
Also double checked the query to make sure the columns of the selected table are of data type TEXT.
I'm at a loss.
