I keep getting a node exists message trying to bring hierarchy load in bw from ecc. when i look at problem records in PSA, they look fine meaning this infoobject is set for 'Entire hierarchy is time dependent'. there were 5 records in the psa but all with different dates yet i keep getting this node already exists for 3 records, the other two are fine. how can i make datefrom and dateto as a key to that node so it always sees it different whenever dates are different? thanks.
