3375790 - Error ME 124 raised while creating a regular PO (not STO)

You create a PO in ME21N using a Vendor/Supplier which has a plant assigned (you might not be aware that there is a plant assignment).

Error ME 124 "Material not subj. to inventory mgmt. in plant" is raised and the reason seems unknown as this should get triggered during STO (Stock Transport Order) creation only.
