Thanks for your response Ram.
My Source System UPFILE is in active mode.
Unsure why system is throwing error as source system assignement was inconsistency.
All fields are mapped perfect with one-one relation.
Worked by reassigning the UPFILE - source system to the data source but still i m seeing the same error : Data Source doesnt exist in source system of version A.
Transported the DS alone to Quality initially where i m unable to find the transported data source in my quality(target). DO i need to perform replicate meta data ...something like that in quality so that imported data sources will get refreshed?
If so can you let me know the approach.
Thanks
