Hi,
(1) It seems that it is part of view cluster SM34 -> /SAPPSSRM/VC_HT.
The error "No functional item exists under item 001" comes if outline item is created but it does not have a any material/service item under it.
If you user template HIER_SE for EXTR this error should get solved. Do below config using SM34 -> /SAPPSSRM/VC_HT. After that, tun report /SAPSRM/PDO_META_INVALID_CONF.
(2) I am not sure about another issue "'External Source of Supply" tab.
