We do create all of our POs with option GR Based IV only.
But one small issue is that....
Ex: GRN is made with posting date of 30.09.2010, then for MIRO, our users posting it with an earlier posting date. And off course system will accept, since MIRO is based on GRN entry only irrespective of it's posting date.
But practically it is not a case same as Invoice received but good not yet received. I know in this case system is checking, whether the GRN is made or not only, but not for it's posting date is earlier than this MIRO's posting date.
We want to stop MIRO, if posting date of MIRO is earlier than GRN posting date.
Is there any workaround for this?
