Hi Thorsten,
Thanks so much for your help. From your information and after analyzed our system that everything are in check except the parallelism, we zeroed in on note 1127194 and 1616401. We used the following commands to dynamically change the Parallel Processes:
1) cd <update directory>/abap/bin
2) SAPup set procpar gt=scroll to bump up all the parameters.
Then we terminated the tp process and also manually changed all the relevant profiles (the instance profile in both the regular and SUM directory and PARCONV.TPP) and then restart (ie Continue) from SUM - We noticed the performance improvement dramatically - It took 3 days to process 20% - And with the change it took 2-3 hours to complete the rest of the 80%. Now I just hope the rest will go smoothly.
Thanks again for sharing with much appreciation !
Best Regards,
Elaine Wolf
