# Product Availability Issues

**Marlin GTX** enables product availability records to be updated using recalculators.

These can be used to resolve issues and **free up products** when they are [allocated to work orders](/gtx/docs/available-product-issues#no-work-order) or [reserved on invoices](/gtx/docs/available-product-issues#no-parked-invoice) that do not seem to exist.

**Product Availability:**

- **Allocated** products are (meant to be) on Work Orders
- **Reserved** products are (meant to be) on Parked Invoices

If the work orders or invoices **do exist** but are unnecessary, they can also be [cancelled](/gtx/docs/available-product-issues#on-work-order) or [closed](/gtx/docs/available-product-issues#closing-parked-invoices) to free up products.

## Allocated Product Issues

If the Allocated product quantities appear inaccurate, it is likely to do with a **work order** calculation issue.

### No Work Order

If the allocated products **do not appear on a Work Order:**

- Select **Tools > Balance Recalculators**

**The Recalculators module will open:**

- **Scroll** all the way to the bottom
- Tick the **Product Work Order Allocation Recalculator** checkbox
- Click the **Run** button (blue arrow) at the top of the module window

The allocated product numbers should be updated to show the **correct quantities**.

### On Work Order

If products are still allocated then they may actually be allocated to a work order.

If possible, you can free up products by **cancelling unnecessary work orders**.

**To cancel a work order:**

- **Select it** in the Work Orders list **(Main > Enquiries > Work Orders)**
- Click on the **Cancel** button (red cross) at the top of the module window

## Reserved Product Issues

If the Reserved product quantities appear inaccurate, it is likely to do with a **parked invoice** calculation issue.

## No Parked Invoice

If the reserved products **do not appear on a Parked Invoice:**

- Select **Tools > Balance Recalculators**

**The Recalculators module will open:**

- Tick the **Product Reserved Order Allocation Recalculator** checkbox
- Click the **Run** button (blue arrow) at the top of the module window

The reserved product numbers should be updated to show the **correct quantities**.

### Closing Parked Invoices

**If the reserved product numbers are still there:**

- Open the **Business Planner** (Main > Enquiries > Business Planner)
- Click on **Parked Invoices** under the **General** section the right
  - **Warning:** Do not use the Parked Invoices button under the Data Entry section above (or the Invoices module), since it only shows stand-alone Invoices, not ones attached to a booking
- **Review** any parked invoices
- **Void** if no longer needed:
  - **Double-click** to open
  - Click **Void** at the top

Tip

The parking function **can be completely disabled**, if desired. To disable parking invoices please [contact the Megabus Support Team](https://www.megabus.com.au/support).
