Thanks for the reply again. I think I missed saying this part. I will make it clear. I meant to say, in our environment, new fields with data are added within actual tables very frequently. So if new fields (new columns with data – data structure) are added to the actual physical table, how can we ensure the registered tables in the SMC get mapped to those new fields added to the table in the actual database. If this happens very frequently, is there any other way other than admins performing a metadata refresh every time the change happens in the physical table.
