Creating function based on Power BI Parameter table

[Anonymous]

Hello, I am trying to create a function using M that will concatinate two parameter values from a table I loaded into PowerBI to create a functional URL (report server name & Report Path), but I cannot seem to get the function to reference the local table correctly.

My PBI table looks like this:

parameter	value
RptServer	http://<ssrssvr>/ReportServer/Pages/ReportViewer.aspx?
Rpt1	%2fProduction%2fRpt1&rs:Command=Render

My function looks like this:

let RptParam=(TableName,Param) =>

let

Tbl = Source{[Item=TableName,Kind="Table"]}[Data], <-- probably not correct!

param1 = Table.SelectRows(Tbl , each ([parameter] = "RptServer")), <-- hard coded report server path

param2 = Table.SelectRows(Tbl , each ([parameter] = Param)), <-- report I want to call

value1 = Record.Field(param1{0},"value"),<-- hard coded report server path

value2 = Record.Field(param2{0},"value"),<--obtains path based on the report I want to call

urlstr = value1 & value2 <-- concatinate report server to report path to create entire URL to use

in

urlstr

in RptParam

I would then like to call the function by passing in the Parameter table name as TableName, then the report I want the URL for as the Param parameter.

the error I get is:

Expression.Error: The name 'Tbl.SelectRows' wasn't recognized. Make sure it's spelled correctly.

I cant seem to get the query to reference the paramtable table correctly.

Please help me correct this m query.

thank you in advance!

Use this one

let RptParam=(Source,Param) =>

let

param1 = Table.SelectRows(Tbl , each ([parameter] = "RptServer")), <-- hard coded report server path
param2 = Table.SelectRows(Tbl , each ([parameter] = Param)), <-- report I want to call
value1 = Record.Field(param1{0},"value"),<-- hard coded report server path
value2 = Record.Field(param2{0},"value"),<--obtains path based on the report I want to call
urlstr = value1 & value2 <-- concatinate report server to report path to create entire URL to use
in
urlstr
in RptParam

Thank you for responding, but I found another way around this. I still have my sql param table in the database, but I have instead created a view in sql that concatinates the server to the various report paths in a sql view and then pivots the data into a single row with however many reports listed I want to use. Once I import that view into PBI, its a simple manner of creating a measure that uses the proper column. 

FYI, I use this method to allow navagation from the PBI file to an SSRS detail report.

Thanks!

Instead of "Source"  you need to point to the name reference for the other query.
