• Message text: Selected supply sources used; others ignored

What causes this issue?

You selected sources of supply. The sources of supply are assigned to
material and plant where possible. The other sources of supply are
rejected.
If you selected a number of sources of supply, and some or all of these
sources of supply can be matched to a material in a plant, the sequence
for assignment is as follows:
Plant-specific sources of supply have priority over cross-plant sources
of supply.
Therefore all plant-specific sources of supply are selected first. In
addition, a cross-plant source of supply is always selected.
The following priorities apply for cross-plant sources of supply and
for plant-specific sources of supply which exist a number of times:
Regular vendor
Internal source of supply
External source of supply which is not the regular vendor
