Top-Level Process Artifact

Can we please advise about BPMN’s top level process artifact, typically used in cascade, with vertical drop-down similar artifacts, to overview the whole context process in one topical schematic, prior to developing a full fledged model…? Sorry can’t find a way to attach a sample, but I guess most would recognize what I mean.
Thanks, Khaled Aly

Hi,

I didn’t get your question. Could you please explain more what are you trying to achieve?

Best regards,
Yana
