Data loads and Break points in Transformations

Hi BW Experts,

Question 1 :

I am loading data from Cube to Cube. While loading, it is taking 30 minutes to pick the data packets. It is taking more time in Start of extraction itself. Any specific reason why it is taking more time for extracting the data from Cube to Cube.

Question 2 :

How to easily identify the Break-point statement used in transformations. Is there any table to identify. In our project, we have lot of data flows used and i need to identify in which transformations, they are using the BREAK-POINT. Instead of opening each transformations, is there any way to idenity. Please suggest.

Thanks.
