[madhancog]

Hi Gurus,
   I have installed cognos 8.4 BI and configured its work fine,then i installed cognos planning 8.4 contibutor,Analyst in the same machine and it takes the cognos content store as storage and it is configured properly,Now i planned to work on the machine,when i opened the analyst it says that planning store is not there and can it be updted automatically and it does on its own,
Now i need a clarification what is the procedure to store the sample database and work on that from scrartch instaed opening with the existing one.Planning store is manadatory? or content store is enough? let me know the process i am very new to this tool..

Thanks in advance

Planning store is not mandatory, configuring a content store is enough. If you choose to configure without Planning store, the Planning tables (prefixed P) are stored in the content store instead.
