Unexpected inventory count changes and unplanned edits to a bill of materials create real downstream problems, from wrong picks to incorrect allocations. Before you assume a mistake, you usually need one simple answer: who made the change, and what was the reason.

Cetec ERP supports this kind of accountability in two ways. First, department-specific reports can show user activity for common transactions. Second, system-wide usage logs can help you trace edits when a dedicated report is not available.

Use Inventory Activity for Inventory Adjustments

If you are investigating an inventory adjustment, start with the Inventory Activity report. In Cetec ERP, go to the Parts tab, open the Reports dropdown, and select Inventory Activity. The report shows which user performed an inventory adjustment and the reason recorded for that change.

When a Dedicated Report Does Not Exist, Use the Usage Log

Sometimes you are chasing a change that is not covered by a specific report, such as an edit to a BOM. In those cases, you can use the Usage Log to find user activity across the system, as long as the change happened within the last three months.

How to Choose the Right Path

If you know the general area of the transaction, start with the report tied to that workflow, such as Inventory Activity for adjustments. If you are not sure where the edit occurred, or no report exists for that record, use the Usage Log to trace the change across the system.

Key Takeaways

• Use the Inventory Activity report to see who made inventory adjustments and why.
• Use the Usage Log to track edits across the system when a dedicated report does not exist (within the last three months).
• Start with a workflow-specific report when possible, then fall back to Usage Log for broader tracking.
• Clear user attribution supports faster internal follow-up and fewer repeat inventory issues.

Conclusion

When inventory or BOM data changes unexpectedly, you do not want to rely on memory or guesswork. Using the Inventory Activity report and Usage Log in Cetec ERP helps your team identify the source of changes quickly and keep inventory decisions accountable.
