PO Status. Closed for Receiving, closed for invoice

Hi Colleagues,

I would like to know if there is any documentation where I can know more about PO statuses. For example status Closed for Receiving or closed for invoice. How are those created?

Normally we have PO in status either Open or closed but sometimes we have seen some PO's with status Closed for Receiving or closed for invoice and I would like to understand how those PO's had such statuses.

Is it so that for "Closed for Invoice" status you cannot match an invoice in AP anymore?

Thanks in advance for your help
