Background documentation ROLLBACK Locate the document in its SAP Library structure

In a ROLLBACK, all the changes made by a transaction or a subtransaction on the database instance are reversed.

·        Changes closed with a COMMIT can no longer be reversed with a ROLLBACK.

·        As a result of a ROLLBACK, a new transaction is implicitly opened.

In normal database operation, the database system performs the required ROLLBACK actions independently. However, ROLLBACK can also be explicitly requested using appropriate SQL statements.

Example

In a restart, the system checks which transactions were canceled or closed with a ROLLBACK. The actions are these transactions are undone.
