Diagnosis
Possible reasons for this error:

• The "&V1&" field, or the view containing the "&V1&" field, was removed
from the current screen sequence in BDT Customizing. The "&V1&" field,however, is defined as a required entry field in the field statuscontrol.

• The system should always navigate to the "&V1&" field, although it is
not represented in the current transaction.

System Response
It is not possible to navigate to the field.

Procedure
Correct BDT Customizing. Never set a field as a required entry field inthe field status control if this field is not set to active for thecurrent application.
