BPC NW 7.5: bpc process chain need some setting manually in BW?

hi gurus

when i configure for example:

- load of master data
- load of transaccional data
- run consolidation
- run eliminations
all through data manager (bpc layer), i ve read that this executes on background some standar bpc process chain

so my question is do I have to configure something on this bpc process chains direct on BW? or is it kinda transparent for me?
since I just configure at bpc layer (data manager).
