I am running DMVs against datsets in our Premium PowerBI Service. I was interested in analysing and documenting the M-Code behind the PowerQuery queries so I ran the following query in SSMS. This connected to a dataset called "Timesheet" behind a PowerBI file of the same name.
Select *FROM $System.DISCOVER_M_expressions
I get a single row result back called "Agile CC" (see below).
I assumed this result meant there is only one M-Query (M-Expression) - called "Agile CC" in this dataset behind my "Timesheet" PowerBI report. However, when I download the PowerBI file, it is clear there are many queries (25 based on the view below) in the report/dataset. For each of these queries I can see M-Code behind them (for example the "EDW Calendar WorkDate query" see below) , that isn't returned or visible from the results of the"DISCOVER_M_EXPRESSIONS" query.
Can someone explain why I see more M-Code in the PowerBI file, than I can from the M_EXPRESSIONS query?
Thanks in Advance
Steve
example of query visible in the advanced editor of the PBI file, but not in the results of the DMV
Articles I have reviewed trying to understand this.

@amitchandak I have double checked this (by replicating the issue on a new PBI dataset in premium workspace), and it turns out credentials are not the problem.

Did you ever resolve this issue? I am seeing the same behavior.
