How to modify the addition period of an invoice line to a CIP Asset

Hi

By mistake I added an invoice line to a CIP asset in the wrong period (March instead of April), this was due to the period not being closed yet. I need to change this, I need to cancel the addition and do it again on the correct period.

Is there a way to do this?

If not, what is the best workaround?

If I retire the invoice line can I add it again?

Thanks
