Not much has changed between Business Rules and Calculation Manager when using the CmdLineLauncher for loading with a runtime prompt file.

steps

The solution to using CalcMgrCmdLineLauncher.cmd with Runtime Prompts AND getting multiple values passed in to work as they have previously.

Create a string value in variable manager of Calculation Manager
Create the substitution variables in the application (Planning in this case)
Process the rule from command line like: CalcMgrCmdLineLauncher.cmd [-f:passwordFile] /A:appname /U:username /D:database [/R:business rule name | /S:business ruleset name] /F:runtime prompts file
