Duplicates in Dimension tables when many SCDC controls run in Parallel
We have six packages that all have SCDC controls running in parallel they create duplicate row(s) in dimension tables, When i create a unique index on the Business Key columns the SCDC control fails with unique key constraint violation.
However when i change the packages to run in sequence this issue is resolved.
We are using "Dimensional Merge Slowly Changing Dimension Transformation V1.6 for SSIS 2008 X86"
did anyone face a similar situation.
