How can I use degenerate dimension in another fact table?
By definition, a degenerate dimension is one where the attributes are kept with the measures in the fact table, and not in a dimension table.
E.g, if you fact table is for retail sales, then the receipt number would be kept in the fact table, as otherwise you would be creating a dimension with a cardinality comparable to that of the fact table.
So, I’m having some trouble understanding your question. How can the degenerate dim be kept on a different fact (sic) table? How would you join the two? If you have a key to join, then it’s not a degenerate dimension.
If you mean “can I join two fact tables by a degenerate dimension attribute” the answer is probably not. The join would most likely be many to many, and it would involve joining two huge tables, which would be highly expensive.
