## Technical Information
The restore works by undoing all the changes listed in the [MPE_AUDIT](/tables/mpe_audit/) table. The keys from this table (since and including the version to be restored) are left joined to the base table (to get current values) to create a staging dataset, and then the changes applied in reverse chronological order using [this macro](https://core.sasjs.io/mp__stripdiffs_8sas.html).

This staging dataset is then submitted for approval, providing a final sense check before the new / reverted state is applied.
Source code for the restore process is available [here](https://git.datacontroller.io/dc/dc/src/branch/main/sas/sasjs/services/editors/restore.sas).
