In some cases you may have entered the wrong invoice date or a date on the invoice does not correspond with the date that your stock was received. You may have a high Actual Usage one week and very low one next week. This may mean that you have included an invoice in one week that actually was for a different week.
To Change the Date of an Invoice
Click Invoices from the Button Bar.
Or from the Upper Menu, click Purchasing | Invoices.
The Select Invoice window will appear.
Highlight the Invoice that you want to change the date.
Click on the Change Invoice Date button.
Enter the New Date.
Click Save.
This will not re-adjust your inventory levels but for
reporting purposes will give correct information within the date
range.
