Compensation handling within a BPEL process


Compensation is a new paradigm in the programming context. This helps to do a business rollback. This is applicable to the idempotent transaction context. Transactions which are committed during the business process execution that require a business rollback can be accomplished using the compensation handler. A compensation handler helps to rollback the transactions that are completed in the previous steps of the BPEL process.

The following screenshot shows the compensation handler in the main scope. A compensation handler can be added to the unit scope level as well.
