How To Fix MC748 - View field &-& (data element not adjusted to base field)

SAP Error Message - Details

• Message type: E = Error

• Message class: MC - Aggregate: views, matchcodes, lock objects

• Message number: 748

• Message text: View field &-& (data element not adjusted to base field)

What causes this issue?

A Basis field whose data element was changed is used in the view. Since
the data element of the Basis field should be used as a data element of
the view field, this change was also executed for the view field. (A
change in the Basis field only has no effect if the data element of the
view field was purposely defined to be different from the data element
of the Basis field. Any intentional change can be implemented for SQL
views using the modification flag 'Mod' and for CDS views using a Cast
on a deviating data element.
