I have a simple table which has a number(say sales) as one column which describes the sales done for a product. I also have ~25 products.
Now, I want to import this sales as a measure into cube. However, i am not sure what it's type and sql parameters should be. Setting the type to 'number' and sql to 'sales' gives error such as column "plan.sales" must appear in the GROUP BY clause or be used in an aggregate function.
What am I doing wrong?
