How to avoid loading dimensions that not exist in the fact table
- Anonymous5 years ago
Hi Anonymous ,
According to my understand, you want to keep rows in Dimension table matched from Fact table.
You could select Dimension table --> use Merge-->Right Outer-->Remove unnecessary columns as shown below:
If the data is continuous, you could add the whole column in Fact table as new Query ,then use it to create a parameter to filter the column in Dimension like this:

I must load the dimensions that exists in the fact table.
Have you understand my Q correct?
Hi,

As you see in the picture
pk_installations 50-100 not needed for filtering the fact table.
I don't want them to be loaded to the dataset.
In the real tables I have 3million of rows in the dim table, but I have incidents on maybe 1 miljon of the dimension rows.
So 2 million of dim rows not needed. Will take time to load and will consume memory.- Anonymous5 years agoNot applicable
