AP Invoice - after clicking on distribution lines then unable to amend any other details
I am getting very few details from a user but wondered if anyone can answer the following question.
The user enters an invoice(he doesn't say when and cannot give me an example either). Basically they say after they have clicked on distributions, they are unable to then amend any supplier, invoice number or voucher number details.
Is this normal functionality ?
At what point can you amend and cannot amend.
Any details welcome.
Thanks
Sue
