what are the enhancements made in datastage 7.5 compare with 7.0

Many new stages were introduced compared to datastage version 7.0. In server jobs we have stored procedure stage, command stage and generate report option was there in file tab. In job sequence many stages like startloop activity, end loop activity,terminate loop activity and user variables activities were introduced. In parallel jobs surrogate key stage, stored procedure stage were introduced. For all other specifications, please refer to the manual.raj.

As of my knowledge the main enhancement i found is we can generate reports in 7.5 where u can't in 7.0

and also we can import more plug-in stages in7.5

Complex file and Surrogate key generator stages are added in Ver 7.5
