In Version 8.450 users may receive a warning when receiving a Supplier Invoice that the Receipt and the Invoice dates must be in the same month.
When entering a Supplier Invoice, the Packing Slip date automatically populates with the today's date. We have added in a new default setting under Admin / Defaults / Manage Supplier Defaults - Invoices tab
This has been set to be turned on by default.
This is designed to avoid instances where the Inventory figure and the Purchases figure are affected in different months due to the Products receipt and the Invoice date being different.
This can cause fluctuations in your Profit and Loss as your Inventory value has risen in one month, while the corresponding Purchases figure has risen in a different month.
