Parameters in Dashboard Maintenace Unit

For natural alphabetic sorting and grouping, create this Extensibility Rule and run it.  Viola! Params Sorted like you would expect:

Imports System.Data
Imports OneStream.Shared.Common
Imports OneStream.Shared.Database
Imports OneStream.Shared.Wcf

Namespace OneStream.BusinessRule.Extender.ParameterSorter
   '----------------------------------------------------------------------------------------------------------
   'Reference Code:    Parameter Sorter [ParamSorter]
   '
   'Description:       This class sorts Dashboard Parameters for a given Workspace and Maintenance Unit 
   '                   Sort is standard lexical (Lexigraphical, Dictionary) order
   '                   After running the rule refresh the application and workspace.
   '
   'Note:              This will change sortorder setting on all parameters for the given Maintenance Unit
   '                   (most people want this)
   '
   'Usage:             Update Workspace and Maintenance Unit strings then run from the BR Editor.

From the docs*:

When a parameter is created an API call is made to the weather beareau to identify the wind speed (km/h) at the location of the hosted environment. This wind speed is multplied by the amount of cats in your street divided by the amount of minutes you have spent searching the list for parameters in your OneStream career. The result is then used as a seed for a random number generator to determine the sort order of the newly created parameter.

Sorry looks like it is random after all!

If anyone does want to sort them alphabetically with a BR, check out Robb's post for some code to tidy it up: https://community.onestreamsoftware.com/t5/Productivity/Alphabetically-sort-list-of-dashboard-parameters/idc-p/19595/highlight/true#M450 . Of course the above logic will apply again when you insert a new param.
