I am using Load Transaction data BW info provider UI to load transaction data from BW cube to BPC cube. In the data manager package there are options in data transfer mode as
1. Aggregrate Overwrite
Also in Load Transaction data from BW Infoprovider UI there are options of
1. Merge data
2. Replace and clear data values.
What is the best practice and is there an option of delta load since lot of records are getting created on each load.
