Hi Thorsten,
By the way do you have any suggestions for this 
.. as i cant see many people responding to my query.
I divided COMPONENSTS0001 into 4 parts doing 250k each.
The first one i ran individually & it completed in approx 1.5 hours, where when i ran rest of 3 together It took 8 hours which was bit weird.
So I am not sure was this the size of data which might have differed in first one & rest of 3.
Warm Regards
Ajay
