## Lub Oil Ordering
The ordering is carried out via purchase orders. It can either be initiated directly from the catalog or from the purchase module.
To use catalogs directly, please go to Stock → Catalogs tab.
Find and confirm the desired articles. Further articles can then be added in the RQ via `Get article from Catalog`.
If the items of the PO are marked as received, the corresponding entries are written to the Lub Oil Module as bunkering.
To receive items, please hit button Receiving/Reporting -> Receive Items in Purchase module.
By default, the full quantity will be preselected. Please adjust if necessary.
## Lub Oil
The entries can then be seen (summed up if there are several POs) in the overview per vessel. As well as listed individually in the bunkering overview. Here you also have the link to the corresponding PO.
## Consumption
The consumption is currently entered in the Lub Oil module.
After entering the consumption, we calculate the ROB and the current price.
Furthermore, there is also a complete overview here.
