Cannot cancel an Invoice

[James Jesudason]

When you create an Invoice and then try to cancel it, you get the following message:

"You can not modify a posted entry of this journal !
You should set the journal to allow cancelling entries if you want to do that."

When going to Accounting > Configuration > Financial Accounting > Accounts > Journals and looking at the 'Sale Journal' (or any journal), there is no option to allow cancelling. This option exists on version 5.0, but does not appear on version 6.0. Has this been deliberately removed? If so, the Invoice screen shouldn't have a 'Cancel' button. However, my preferred solution would be to put back the old functionality of allowing users to be able to set a journal to allow cancellations.

Hello James,

Version 6 has a bit different workaround to cancel the invoice using that option.

You will need to install 'account_cancel' module.

Thanks.

Is there any documentation on this? If this is the new approach then you should change the message to mention the account_cancel module, as currently it doesn't make sense.

From a user point of view, having a 'Cancel' button that will never work doesn't make sense. A suggested approach is:

1. Check to see if the account_cancel module is installed.
2. If installed:
        Use the existing message about the Journal.
    else:
        Submit a message saying that the account_cancel module needs to be installed to allow cancellation of posted invoices.

This approach will help to make the system self-documenting.
