SAP Error Message - Details

• Message type: E = Error

• Message class: DMC_RT_MSG - DMC: Runtime Object Messages

• Message number: 635

• Message text: Field &2 in parent structure &3 cannot be 'Not Visible'; see long text

In parent structure &V3&, field &V2& is set to ?Not Visible?. However,
in the child structure &V1&, this field is set to ?Visible?. This
situation is not permitted, as field &V2& is part of a foreign key
relationship. Either the field in the parent structure must also be set
to ?Visible?, or the field in the child structure must be set to ?Not
visible?. You therefore need to change the visibility of field &V2& for
the active view.

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