Full DTP taking too much time to load

Hi All ,

I am facing an issue where a DTP is taking too much time to load data from DSO to Cube via PC and also while manually running it.

There are 6 such similar DTP's which load data for different countries(different DSO's and Cubes as source and target respectively) for last 7 days based on GI Date. All the DTP's are pulling almost same no. of records and finish within 25-30 min. But only one DTP takes around 3 hours. The problem started couple of days back.

I have change the Parallel processes from 3->4->5 and packet size from 50,000->10,000->1.00.000 but no improvement. Also want to mention that all the source DSO's and target Cubes have the same structure. All the transformations have Field Routines and End Routines.

Can you all please share some pointers which can help.

Thanks

Prateek
