I have a one to many to many relationship; with the "Cascade update related fields", and "Cascade update related records" on the relationship properties checked.

since I have split the DB to FE and BE, the relationship properties (for the 3 tables on the FE) is grayed out and cannot be changed.
In addition, the "Cascade update related fields", and "Cascade update related records" on the relationship properties is unchecked.

(The relationship properties on the BE is still configured to Cascade update.

Any solution?

Thank you
Joe
