however, I need check BW report with R3 immediately, I'll be very appreciated if anyone can help me.
Furthermore, I have deleted many PSA data loads.

Here are some other things that you can do, or have done, to help:
1) Delete Change Logs that are more than 21 days old (or some other aging).
2) Have your Basis DBAs do a reorg on the underlying tables for larger DSOs.
3) Run compression on larger InfoCubes.
4) Archive data that is older than two years (or some other aging).
There are other things you can look at, but will take more time to complete. For example, if you're using the 0EC_PCA_3 DataSource for extracting PCA details, it extracts 3 records (one per currency type - transaction, local and operating concern) for each row of data that's in R3/ECC. Instead of using that DataSource, one could create a generic DataSource based on Function Module to pull 1 record for each record in the table, significantly reducing the amount of data (requires some other actions on the reporting end though so that users can choose which currency they want to report in).
