A common cause of database timeouts is the creation of records like **Incidents**, **Service Requests**, **Changes**, or **Tasks**, where the **Display Name** (Owner) is limited by the **Field Name** (OwnerTeam) in the system.

This issue arises when the **Picklist: DisplayName of Employee with LoginID value** by **Team** is used. If the Team value is missing or null, the system may experience delays, resulting in a timeout during the record creation process.

To fix this issue, the **Picklist** configuration must be updated to include a null check for the **Field Name** (OwnerTeam). This ensures that the system handles missing or empty values, preventing performance issues and avoiding database timeouts when the query is executed.

The updated configuration should align with the Out-of-the-Box (OOTB) setup, which already incorporates this null check to prevent timeouts.

Steps to update the **Picklist** configuration:

1. Open **Configuration Console** and select **Picklists**.
2. Locate the **Picklist** titled **DisplayName of Employee with LoginID value by Team** and **Click** to edit.
3. Add the following constraint to check for null values in the **OwnerTeam** field:
   - \[StandardUserTeam#.Rev2]Team = $(NVL(\[ValidationList]OwnerTeam, "Empty"))
4. Save the **Picklist**.
