Question: On one of the screens we need to add a field at plan level- plan year end date and add validations to do something based on this field. When I checked the existing screens(& tables in the DB) that have similar functionality- I see that there is one more identity column(other then opportunityID) that gets populated when a new record is inserted. My question- is it possible to add a new identity column to an existing table and populate it with CreateIDFor function- how does SLX DBProvider knows for which column ids should be created? Because I see the parameter that is passed is the table name and number of ids to be created- column name is not there. Is there any other functionality available to do this? Answer: You need to script additional ID fields populations. SLX can/will autopopulate the Primary ID field of an SLX table for you, plus CreateDate/User, ModifyDate/User.
