Compare Text (Node 4)
This Standard function activity compares two text values. At this node, the process checks the Acknowledge Required? item attribute to determine whether the event message sent at node 3 requires an acknowledgement from the recipient.

In this case, the process continues from node 4 to node 5. Otherwise, the process continues directly from node 4 to node 6.
