¿Cómo arreglar este error?

Define rules to unassign orders for an application type in the
Customizing activities under <LS>Cross-Application Components > Advanced
Available-to-Promise (aATP) > Supply Assignment (ARun) >
Cross-Applications</>.
By defining a rule to unassign orders, you specify exactly how the
system should react when an application type is modified (for example,
change in requirement date, goods receipt date, plant, storage location,
and so on).
You set the appropriate fields listed in the application type in
Customizing. For field checks, you can assign one of the following
options:
N,,No Action
W,,Warnings Before an Order Is Unassigned
E,,Changes Not Permitted
Depending on the selected parameter, the system decides how and when the
quantities should be unassigned.
