BPML Activities in Business Process Models
Before each service in a business process model, you must include the Sequence Start BPML activity, and after the service you must include the Sequence End activity. Other BPML activities enable more complex activities.
Some BPML activities must be used in pairs, to bracket other activities. That is, for a given processing step in a business process model, you must use one of these bracketing activities at the beginning and one at the end. These are considered to be parent activities.
This topic explains requirements related to your use of BPML activities in business process models. Your processes may not run correctly if you do not use the BPML activities according to the requirements outlined here.
