I have created a universe on the top of the bex query, in the query i have various characteristic like CID,MID, revenue, calyear and calday.
but when i created the universe, for CID i have got L00, L01 and under L00 i have 4 keys .
My doubt is why so many objects are created for only one characteristic in bi.
Please see the below screenshot .
Please help ASAP.
