In Business Process Management Notation (BPMN), looping is an attribute of an Activity. Any activity (task or subprocess) can be configured to either: not loop; loop in standard mode (‘while’ or ‘do until’ loops); or, support multiple instances (‘for each’ looping).
Standard Loops
‘While’ Loops
This is used to test the condition before the activity is run:
WHILE (condition and Loop Counter < Maximum Loops)
Perform Activity
Note: The Loop Counter is used internally. It starts at zero and increments by one on each iteration.
‘Do Until’ Loops
This is used to test the condition after the activity is run:
DO
Perform Activity
UNTIL (condition and Loop Counter >= Maximum Loops)
