I'm trying to use Flows for APEX to model an approval workflow that has a master-child relationship - like an order header with a various number of order lines. Line approvals are independent, but the header record can't be finished until the approval for all lines has completed.
According to some BPMN document I've read - this should be accomplished with "A Multi-instance activity is indicated by three parallel bars at bottom center."
I can see that the tasks have this notation but no clue how to use it or if it's supported. I've scoured the Flows documentation and have not found an answer but I'm thinking it might not be supported because I don't see the line notation on any tasks in the "Supported BPMN" model. If this type of task is not supported. anyone have any workarounds?
