We have now been working with BAS Insite for some time.

To ensure invoices are processed correctly in the system, the AFAS cost centre number must be stated on them. Make sure you provide your AFAS cost centre number to the supplier when placing your order. Soon, invoices that only contain a SAP number will no longer be accepted.

How do you find the new AFAS cost centre number?

FEZ has developed a useful tool for this purpose. Enter the old SAP number in the tool and it will show you the corresponding new AFAS cost centre number.

What do I use the new AFAS cost centre number for?

You use the AFAS cost centre number when placing an order with a supplier. The supplier must include this cost centre number on their invoice.

You also use this number when creating a personnel change, such as a new appointment, or a change to a project cost centre.

Finally, you use this number to monitor the development of your financial costs in relation to the budget. More information about this will be communicated at a later stage.

Do you have any questions?

If you have any questions, please contact FGGA FEZ or Wesley directly at w.dijkstra@fgga.leidenuniv.nl.
