Inventory Location

Am facing challenges by checking inventory by location
After updating my system all the sales invoices and Payments and receipts are not reflected on those locations where they were assigned
please how can retrieve all those information back to make my inventory by location correct

Can you be more specific? What exactly has changed? When you go to sales invoice edit form, do you see inventory location field at all?

Because, for example, on sales invoices, the field is visible only if not using delivery notes.

There is no Inventory Location

My delivery note has been enabled automtically

If you are not using delivery notes (and have not created any), simply go to Customize and disable the tab. That will shift the location field from delivery notes to sales invoices.
