Hi,
i have only a little experience with MS Access,
i am trying to build an invoicing access database and i have already my Tables , Employs, Customers, Invoices, invoice_details.....
and my forms and some queries...
the problem is: every time i change a product price in my products table, this change will affect all my previous invoices.
i spent a lot of time to solve this issue, i did not succeed.
can you help please ?
thank you all in advance.
