4. What is “parameter”?
Parameters are special variables, which value we can change, to influence the report results or behavior.

5. Various parameter types
“Normal” parameters – often used for filtering *
With free-form values
List of suggested values (static lookups)
Suggested values from query (dynamic lookups)
Connection-specific parameters *
What-if parameters
URL query string parameters

6. DEMO – using parameters for filtering data
Manage parameters in Power Query Editor (“Edit Queries” window)
Define filters in column titles
Use parameters with Report Templates (*.pbit)
Use “Refresh Preview” to refresh dynamic lookups
Use parameters in M code to:
filter data
change report’s logic

7. DEMO – using connection-specific parameters
Not supported by all data sources
Convenient way to change data source
In case of DR
To switch Dev/Prod

8. DEMO – using What-If parameters
For testing What-If scenarios
Interact with a slicer
Creates a parameter and a measure

9. DEMO – using URL query string parameters
Pre-filters the report
Doesn’t work with embedUrl, Publish to web, SharePoint Online, etc.
Works with Secure Embedding
Append ‘?filter=Table/Field op value’ to the URL
Escape special chars in names with ‘_0xDDDD_’, where DDDD is 4 digits Unicode
e.g. space is _0x0020_ and ‘Order Date’ becomes ‘Order_0x0020_Date’ (???)
Enclose string values with single quotes (can’t escape single quotes?)
Do not quote numbers and date/times
e.g. ?filter=SalesOrderHeader/OrderDate ge
Combine multiple filters with and (up to 10 conditions)
Supported operators are eq, ne, ge, gt, le, lt, in
in needs comma-separated list enclosed in parentheses
e.g. ?filter=SalesOrderHeader/CustomerID in (1,2,3)
