Can someone please explain the discrepency

Hi

I am new to BW/BI but I have been on the course BW310. I am following an excercise from the course that creates a cost centre datasource from R/3 and loads it to BW. I am currently loading the attributes.

All is good and I loaded 552 records into the PSA via an infopackage.

I have also created a transformation and DTP to load into the infoprovider object. However when I executed it and checked the data in /bic/qcostcc (the attributes table) I have 792 records in there. I get the same answer in 'maintain master data' for the costcc infoprovider object.

Any ideas Gurus ?
