Need help in understanding Use of DataManager
I have a question concerning the data manager of BPC 7.5 because I do not understand the need of using it in importing master and transactional data. Why must I use BPC DataManager to load Data from BW-Cubes? I mean I could use the BW-ETL process for same purpose, couldn`t I? I have read that there might come up problems with full optimization but is that all or are there more reasons?
