# end storage transaction

This block is part of the [`storage`](https://docs.rual.nl/block-types/storage) group and was last modified in core [`v15.0.1`](https://docs.rual.nl/core-versions/150001).

Commits the storage transaction opened by start storage transaction and stores its result for a later retry of the same id.

- flow `flow`

- transaction id `value` Leave empty to end the transaction open in this flow. A bare id names a transaction this blueprint started; the qualified `bp: : ` reference from the start block names one started elsewhere : allowed only once that run's lease has lapsed.

- result `value` Stored on the record and returned by a later start of the same id : the response a retried request should get.

- flow `flow`

- success `condition`

- transaction id `value`

- transaction `object`

- status `value`

- error `value`

Commits a storage transaction: marks it committed, stores `result` on the record (a later function_transaction_start of the same id answers already_committed with it), releases the opener's lease and keeps the journal for its retention. Without a wired transaction_id it ends the transaction currently open in this flow; after it, writes in this flow are ordinary writes again. Fails with TRANSACTION_NOT_FOUND when there is none, TRANSACTION_NOT_OPEN when it already ended, TRANSACTION_NOT_OWNED when it was opened by another run whose lease is still alive (ownership is the attempt token the start block put in this flow; a wired id carries none). A wired id names a transaction this blueprint started unless it is the qualified `bp:<blueprint>:<id>` reference. `transaction` carries the record (id, status, attempts, op_count, started, ended, result). In simulation nothing is written.

A typical wiring for [end storage transaction](https://docs.rual.nl/block-types/storage/function_transaction_end): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%2520ui/state_debug).
