Well, you don’t win a prize for constructive questioning 
If you had bothered to search you might have found this thread. You didn’t mention what version of what products you are using. Some are more buggy than other, some ‘bugs’ are actually problems with other software e.g. databases, middleware etc. A more constructive question would be to say I am having problems with X, Y and Z - has anyone else encountered this. I don’t think you will find a bug-free piece of BI software, just like you won’t find a bug-free operating system etc etc.
