When a backout is required

A backout is required in the following circumstances:

The conversation state does not always reflect the requirement to back out. However, CICS® is aware of this requirement and converts the next SYNCPOINT request to a SYNCPOINT ROLLBACK request. If no SYNCPOINT or SYNCPOINT ROLLBACK request is issued before the end of the task, the task is abended (ASPN), and all recoverable resources are backed out.
