download customer hierarchy

Hi,

when i download the customer hierarchy object (DNL_BUPA_KNVH), the download runs fine (R3AM1: status is done).

i can see some data in the table CRM_KNVH_TEMP, this means the data has come from R/3.

But i am little lost, when i try running BPH_DNL, i cant see any hierarchies??? why is this happening??

pls help
