System Response

Every material/store combination must have exactly one main vendor
assignment at the given key date. Hence, it is not allowed to remove a
main vendor assignment without selecting another vendor to be the main
vendor for this material/store combination.

How to fix this error?

You must select one vendor as main vendor for those material/store
combinations that currently have no main vendor assignment.
You can use the toolbar function "Show/Hide Missing Main Vendors" to
display the material/store combinations that do not have a main vendor
assignment. In this filtered view, you also have the option to set all
missing main vendors in one step, by using the function "Set Missing
Main Vendors". If required, these main vendor proposals can be adjusted
manually.
