How to handle single quotes in Inline Load

You can enclose field names in [ ], ` `, ´ ´ and " " pairs. So try it like this:

LOAD * INLINE [

    F1, F2

    Actuals, sum({$<"Source Name" = {'Current View'}>}"Outlook Units")

];

Or if you have no double quotes in your expressions try:

LOAD * INLINE "

    F1, F2

    Actuals, sum({$<[Source Name] = {'Current View'}>}[Outlook Units])

";
