Change Request

Hi,

Suppose a query is been transported from Dev to Staging. Now when we perform any chnages to the query in DW1, it will ask for a change request and we give some request Number. After we transport the new change request, does the old request still visible in SW1? When we are puling the query from staging to production, which request it pulls, old one or new chnage or both requests..

thnx
