Hi Arti,

How are you doing? You can create staging area for your first dimension and then create your second dimension with this staging area.I think You need the pramary key of first dimension.

Hi Satish

My question is, in the target i created a fact table and added the dimensions to it, but now when i'm trying to add another dimension to the already existing dimension table it wont let me do it. I hope i explained my problem clearly?

Were you able to find an answer? I am also trying to extend the dimension (add tables) to create a snowflake. I thought that once I select the snowflake option I will see in detail view separate tables per level, but it did not happen.

Unfortunately no, but i'm following a different approach...........instead i'm using the SQL*Loader and using the "loading nested column objects" option.It works fine so far. Smile In this way we need not opt the snowflake schema.
