Hi Friends,
I'm New to this community and also to cognos 8.
I have learned cognos 7.2. Now i need to create a cognos cube and Publish it in 8.2.
Could you please tell me the steps to Create the cube and Publish it.

At present i create the cube in Powerplay transformer and use framework Manager to Publish it.
i.e., import the cube while creating the Data Source.
But there i face some problems (error and Updation of data's)

I will be happy if i get a quick reply.
