Using delete flags you can set up for relations and links which operations will be automatically executed for dependent master elements by DataView if a user deletes a relation record in a relation table (for relations) or a record in a linked table (for links).

The values you can enter into the delete flags to control deleting and the operations DataView will execute depending on the relation, can be found in the following table:
Please note that the delete flag procedure is functionally connected with the standard procedure for securing referential integrity without any user activities required. Additionally, already defined check values have thew following effects:
Example: In the meditronic application deleting an Item-Supplier relation (item is not provided any longer) is to have the effect that also the supplier is automatically deleted in the supplier master. The delete flag entry > = D in the refine relation Item-Supplier assures that.
