Doubts in Classic Scenario

Hi Friends,

i am having a doubt...

Let’s say in classic scenario

1) SHC created in SRM

2) PO replicated in ECC in Editable mode & in display
mode in SRM

Question 1:

If I change PO qty in ECC(as its in editable mode) will it get updated in SRM PO?(i.e changes we do in PO at ECC level will be updated in SRM?)

Question 2:

If I do Goods receipt & Invoice in ECC  for the same PO will it replicated in SRM as GC and Invoice against the PO?

Thanks,

San
