Error: The value is not a cube

[PowerBWhy]

This technique was taught to me by someone I unfortunately no longer have access to. I can't get it to function properly and haven't found any answers searching around.

I am importing data through a SAP Business Warehouse Message Server and selecting a parameter for an arbitrary set of weeks. I also have a date table which I am dynamically filtering with date fucntions to get a list of the previous 5 weeks. From that filtered table I am creating a custom text column to match the format of how the date appears in the sap parameter. I am then taking that custom column and adding it as a new query titled "List."  I am then wrapping that query formula in {} to convert it to a list. Finally, I am replacing the sap date paramenter with List{0}} but I am getting an "Expression.Error: The value is not a cube. Details:[Table]". To verify that my custom text column is functioning correctly I have copied a single value from the list and pasted it in the parameter and it works.

What could be causing this issue? Am I properly using the list? Sorry if there are gaps in my description. I am fairly new to using PowerBi and SAP.

Thank you.

Hi @PowerBWhy 

"From that filtered table I am creating a custom text column to match the format of how the date appears in the sap parameter. I am then taking that custom column and adding it as a new query titled "List." "

Could you show me what you create or the code in Advanced editor?

Do you create parameter on SAP side or on Power BI side?

@v-juanli-msft Thanks for your reply. I am creating the parameter in SAP BEx editor by selecting a set of dates then attempting to edit that code with a query that is a dynamic set of weeks formatted as a list. Sorry if that didn't answer your question as this is something that is fairly new to me. I will detail my code below.

This is the code as it comes ffrom BEx editor before manually making any changes:

Here is the code creating the list that I am attempting to pass through the SAP parameter. Along with an image showing the formatting of the values before converting to a list:

Finally an image when I attempt to pass the list through the SAP parameter:

Thank you.
