Repost Item Valuation

Can anyone explain to me what exactly is Repost Item Valuation
I try to understand what this doctype does but with no good information like
1- does what?
2- help in what?
3- is okay to cancel running one or queued one?
4- what is the benefit of this doctype?
5- creating manual Repost Item Valuation will help in what?

because every time I try to delete and re-upload an invoice this doctype slows my work. also, because there is one in the background-job that will let the bench restart action freeze and wait until the repost to finish or I need to do sudo reboot

Thanks in advance
