## How Vault Creates Scheduled Signal Reporting Periods {#how-vault-creates-reporting-periods}
After running the _Schedule Signal Review_ action on a _Signal Product Profile_, Vault:
1. Creates a _Schedule Recurrence_ record for the _Signal Product Profile_ with the following information:
* **Schedule**: Vault maps this value from the _Signal Product Profile_.
* **Start Date**: Vault populates the current date.
* **Signal Product Profile**
* **Recurrence Type**: Vault populates _Signal Product Profile Recurrence_.
* **Lifecycle State**: Vault sets the state to _Initialized_.
2. For the _Schedule Recurrence_, creates _Scheduled Events_ for up to one year in advance based on the _Schedule_ of the _Signal Product Profile_. For example, if the _Schedule_ is _Monthly_ and the _Start Date_ is _05 Dec 2025_, Vault creates a _Scheduled Event_ for each fifth of the month until _05 Nov 2026_.
3. On the _Scheduled Date_ of each _Scheduled Event_, runs the _Safety Scheduler Job_.
4. After the job runs, creates a _Signal Reporting Period_ if one does not already exist for the _Signal Product Profile_, _Product Family_, _Start Date_, and _End Date_ combination. Vault then completes the reporting period with the following information:
| Field | Description |
|---|---|
| Lifecycle State | If Veeva Safety Signal is enabled in your Vault, Vault sets the lifecycle state to the Queued state type. If only Veeva SafetyDocs is enabled, Vault sets the lifecycle state to the Initial state type. |
| Start Date | Vault populates the Start Date with the Scheduled Date of the Scheduled Event. |
| End Date | Vault populates the End Date by subtracting 24 hours from the Scheduled Date of the next Scheduled Event. |
| Review Type | Vault populates Routine, indicating this reporting period was created from a schedule. |
| Next Signal Reporting Period | Once the next Signal Reporting Period is created from the schedule, Vault uses it to populate this field. |
| Previous Signal Reporting Period | Vault populates the Signal Reporting Period from the previous scheduled review. |
) icon or from the **All Actions** menu, select **Cancel Scheduled Signal Review**. You can run this action only if a _Signal Review Schedule_ has already been initiated.
**Results**
Vault updates the _Signal Product Profile_ as follows:
* Sets the existing _Signal Review Schedule Recurrence_ to _Cancelled_.
* Deletes incompleted _Scheduled Events_ from the existing _Signal Review Schedule Recurrence_.
* Sets the _Schedule Termination Date_.
Vault does not delete any _Signal Reporting Periods_ from the _Signal Product Profile_ even after canceling a signal review schedule.
If you want to reinitiate the signal review schedule for this _Signal Product Profile_, you can [schedule the signal review][1] again.
