Can we perform MR11 eventhough GR archived from the system

Hello All,

I am having a situation where user want to do MR11 for a PO for which material document (i.e. GR document) has been archived from the system?

Presently when we are executing the T.code # MR11 for PO, it gives us the screen where we can't select the document and not showing any value as well.I think this is becuse of GR has already been archived.

Can we do this,

If yes, what's the process, (but at the same time business doesn't want to unachieved the document.)

If not, any reason, apart from GR archived.

Thanks and Regards
