Master data load to Dimension

Hi,

I am trying to load master data from BW to BPC for Account Dimension. I have few questions.

1. While loading the data, do i need to mandatory set the selections for the BW Info object?

I loaded the data without setting the selections. I got 0 records.

But, when I load the data with selections in the SET SELECTION, I was able to load the data.

SET SELECTION:

Master data loaded successfully.

2. While debugging the transformation file, the structure of START ROUTINE AND END ROUTINE is the same.

Is this correct or am I doing something wrong? As in BW transformations, Start routine will have the structure of SOURCE  and End Routine will have the structure of the TARGET.
