I saw legacy code in my works that contains pub.report:runStringTemplate service calling. The $template input variable has a value that looks like: %ifvar Abc equals(‘TRUE’)%DEF%else%ZZZ%endif%
It seems the runStringTemplate has its own language for the $template input.
I found the explanation of runStringTemplate in Integration_Server_Built-In_Services_Reference.pdf is very scarce. There is no mention of ifvar.
So where can I find the comprehensive documentation and example usage of pub.report:runStringTemplate ?
