I have a bunch of Tables in DA Schema that are in a master-detail relation. One example is customer table and activity table, customer being the master table. My primary key in the Customer table is a string. What i want to do is something similar to what dataabstract does with the generator and the AutoInc fields, meaning that in the update process it also changes the keys in the detail table so it matches the new master key. Can something like this be achieved?
