DeleteConstraint: RdsConstraintType;
The DeleteConstraint property determines the behavior on attempt to delete elements in the linked dictionary.
Executing the example requires the MDM repository NSI_1 that contains an MDM dictionary with the Dict_1 identifier. The dictionary includes the link with any other MDM dictionary.
Sub Main;
Var
MB: IMetabase;
MObj: IMetabaseObject;
Dict: IRdsDictionary;
Link: IRdsLink;
Begin
MB := MetabaseClass.Active;
MObj := MB.ItemByIdNamespace("Dict_1", MB.ItemById("NSI_1").Key).Edit;
Dict := MObj As IRdsDictionary;
Link := Dict.Links.Item(0);
Link.DeleteConstraint := RdsConstraintType.Cascade;
MObj.Save;
End Sub Main;
After executing the example link parameters of the Dict_1 dictionary are changed. While deleting elements in the linked dictionary, elements that have links on the deleted element are also deleted in the current dictionary.
