How You Enable Audit Trail for Manufacturing Work Orders

If you're an application administrator, you can enable audit trail for manufacturing work orders to comply with the US Code of Federal Regulations (CFR 21 Part 11) for electronic record and electronic signature requirements. By doing so, you let your internal and external auditors have more visibility of the work order change history.

Here's the list of work order entities for which you can enable audit trail:

Work order
Work order operation
Work order operation material
Work order operation resource
Work order operation resource instance
Work order operation material lot
Work order operation material serial
Work order operation material substitutes
Work order product serial
Work order operation output

What happens when you enable audit trail:

The work order updates if any, are automatically tracked in the audit tables.
The audit records capture the attributes that got updated. The records also capture the old and new values for each update, the date of the update, and the user who performed the update.
You can search the change history for a specific work order.

Here are the different modes of updates which are supported for audit trail:

Work order create and update actions are performed in the Manage Work Order page.
Work order update action is performed in the Edit Work Order page.
Work order create and update actions are performed through work order REST services.
Work order update actions are performed through the FBDI process, SCO, and work order transactions.

Here's the list of work order attachments for which you can enable audit trail in the Manage Audit Policies Setup for Work Orders page:

Work order operation
Work order operation material
Work order operation resource
Work order operation output

In addition, you can enable audit trail for the project manufacturing attributes in the Manage Audit page.
