Hi Vinod,
Thanks for your inputs.
"If any query is running on top of this dso (without sid) the sid will be generated during run time." - If this is true, then I guess I would need to turn on the SID generation because query performance will be slow if SIDs are being generated at the time the report is run. Definitely i don't want that.
"I will suggest check the master data object datasource - load data into DSO using the same IP and see, you should get the delta option, as new request can be loaded into dso." - Great suggestion, I should certainly look into this as an option.
