I set "Modify Once" property for one field of my repository table in MDM Console, but i can modify it after
initial upload from import manager or after creation in MDM Client. Whats the matter?
To add on to Ronen's comments, this feature is not fully implemented as of now (SP2 5.5.24.06). Which means, say I add a code of 99 and description of TEST in my table A. Then, if I have Modify Once set to YES on Code, then I should not be able to go and modify the 99 to 100 for that record. However, as of now, you can modify the code to 100.
My understanding is Modify Once will start throwing an error (and will not let you modify the value of that field) starting SP3 (target release towards end of this calendar year).
One last note, Modify Once in my view is a way of enforcing the primary key feature of Oracle that you cannot overwrite a primary key value.
Hope this helps
