Dear Ling,
There is a standard program RPUP2D00 but it is recommended to never delete the B2 cluster results in Production environment as it creates inconsistency. If it is quality, test or dev system then you can use this report. There is another standard report PT_BPC10 that can be used for fixing many of the issues. Please let me know why you want to delete the cluster results and I can suggest an alternative fix for the same?
Regards,
Anand Jalan
