Ref. operation set & is not valid according to the selection conditions

What causes this issue?

The selected reference operation set &V1& is not valid on &V2&.

System Response

If default values have been maintained in Customizing, an operation is
generated automatically.

How to fix this error?

Check why the reference operation set does not meet the selection
conditions:
Is it valid on &V2&?
Is lot size &V3& within its validity area?
Is the selection ID for routing selection (Customizing: order type-
dependent parameters) of a type that allows reference operation sets to
be selected?
If the reference operation set has a change number, is it valid for
production on &V2&?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
