## Troubleshooting

### Issue: Materials Not Appearing in Inventory Search

**Symptoms**: Users cannot find materials when searching or selecting from dropdowns

**Solution**:

{% stepper %}
{% step %}
Verify the material record exists in the **Materials** (im\_material) table by navigating to the table and searching by name or catalog number
{% endstep %}

{% step %}
Check material status - inactive or archived materials may not appear in searches. Open the material record and verify the status field is set to "Active"
{% endstep %}

{% step %}
Confirm user permissions - ensure the user has read access to the Materials table. Check team and project permissions in **Admin > Personnel**
{% endstep %}

{% step %}
Check available inventory - if the material has zero quantity in all batches, it may be filtered out in some views. Navigate to the Batches table to verify quantities
{% endstep %}

{% step %}
Refresh browser cache or log out and log back in if permissions were recently updated
{% endstep %}
{% endstepper %}

### Issue: Inaccurate Inventory Quantities

**Symptoms**: Reported inventory quantities don't match physical counts

**Solution**:

{% stepper %}
{% step %}
Review recent consumption records in the **Consumption** table - filter by material and date range to identify discrepancies
{% endstep %}

{% step %}
Check for unreported consumption - survey laboratory staff about recent usage that may not have been recorded
{% endstep %}

{% step %}
Verify batch quantities in the **Batches** table - ensure all batches are accounted for and quantities are correct
{% endstep %}

{% step %}
Conduct physical inventory count:

* Locate all containers of the material
* Count actual quantities
* Compare to system records
* Document discrepancies
  {% endstep %}

{% step %}
Create inventory adjustment records:

* Add consumption record for unreported usage
* Or create adjustment transaction with reason code
* Update batch quantities to match physical count
* Document reason for discrepancy in notes
  {% endstep %}

{% step %}
Implement preventive measures:

* Train staff on consumption recording procedures
* Enable barcode scanning to reduce manual errors
* Set up regular cycle counting schedule
* Review and improve procedures
  {% endstep %}
  {% endstepper %}

### Issue: Expiration Date Alerts Not Triggering

**Symptoms**: Materials expiring without advance notification to laboratory staff

**Solution**:

{% stepper %}
{% step %}
Verify expiration dates are entered correctly in batch records - navigate to **Batches** table and check expiration date field format
{% endstep %}

{% step %}
Check alert configuration settings:

* Navigate to **Settings > Notifications**
* Verify expiration alert is enabled
* Confirm alert threshold (e.g., "30 days before expiration")
* Check alert recipients
  {% endstep %}

{% step %}
Verify email notification settings:

* Check user email addresses are current
* Confirm email notifications are not blocked by spam filters
* Test email system functionality
  {% endstep %}

{% step %}
Run expiration report manually:

* Navigate to **Reports > Expiration Report**
* Set date range to identify expiring materials
* Generate report to confirm data accuracy
  {% endstep %}

{% step %}
If alerts are still not working, contact Labii support with:

* Screenshot of alert configuration
* Example of material that should trigger alert
* Expected vs. actual notification timing
  {% endstep %}
  {% endstepper %}

### Issue: Unable to Receive Materials - Missing Vendor

**Symptoms**: Cannot complete receiving process because vendor is not in system

**Solution**:

{% stepper %}
{% step %}
Navigate to the **Vendors** (fn\_vendor) table from the Inventory Management application
{% endstep %}

{% step %}
Click **+ Add** to create a new vendor record
{% endstep %}

{% step %}
Enter minimum required vendor information:

* Vendor name (required)
* Vendor contact information (optional but recommended)
* Save the vendor record
  {% endstep %}

{% step %}
Return to the receiving workflow and refresh the vendor dropdown to see the newly created vendor
{% endstep %}

{% step %}
For frequently used vendors, consider bulk importing vendor data:

* Prepare vendor list in CSV format
* Use **Import** feature in Vendors table
* Verify imported vendors
  {% endstep %}
  {% endstepper %}

{% hint style="info" %}
Encourage purchasing team to maintain vendor records proactively to streamline the receiving process.
{% endhint %}

### Issue: Storage Location Dropdown is Empty

**Symptoms**: When assigning storage locations, no options appear in the dropdown

**Solution**:

{% stepper %}
{% step %}
Navigate to the **Storage** (core\_storage) table to verify storage locations exist
{% endstep %}

{% step %}
If no storage locations exist, create your storage structure:

* Start with top-level locations (buildings/rooms)
* Add storage units (freezers, cabinets)
* Define specific positions (shelves, bins)
  {% endstep %}

{% step %}
Verify storage location status - locations marked "Inactive" or "Decommissioned" won't appear in dropdowns
{% endstep %}

{% step %}
Check filtering settings in the storage location widget - some views may filter by storage type or availability
{% endstep %}

{% step %}
Return to the receiving or transfer workflow and refresh to see available storage locations
{% endstep %}
{% endstepper %}

### Issue: Batch Selection Shows No Available Batches

**Symptoms**: When recording consumption, no batches are available to select despite material being in stock

**Solution**:

{% stepper %}
{% step %}
Verify batches exist for the material:

* Navigate to **Batches** table
* Filter by the specific material
* Check that batches have quantity > 0
  {% endstep %}

{% step %}
Check batch status - only batches with "Available" status will appear for consumption
{% endstep %}

{% step %}
Verify batch has not expired - expired batches are automatically excluded from selection
{% endstep %}

{% step %}
Check project or location filtering - some consumption widgets filter batches by project assignment or storage location
{% endstep %}

{% step %}
If batches should be available but aren't showing:

* Clear any filters in the widget
* Refresh the page
* Check user permissions for batch records
  {% endstep %}
  {% endstepper %}
