Is that something like ROW_WID=0?
In this case you no need to worry, these are required to join with fact table with all possible scenarios.
If something else let me/us know
if helps pls mark as correct/helpful
I'm not clear what you say!.
If there is a record in dimension table with row_wid=0 and in the fact for the same column you might have value as 0
dim table value = fact table column value are matching
so you see a empty record.
Try to load data in required tables
Hope this helps
