getting data from REGUP table

Hi All,

I am working on a report where i need to get the data from few tables and get it displayed, in the requirement I need to get some data from REGUP based on the vendor and then I am trying to retrieve the information from PAYR table such as check #, check date. So far I have tried selecting the information from REGUP using the vendor number entered by the user and then I am doing a select on PAYR to get the other information for all the entries in my REGUP internal table. Using a simple select statement is taking lot of time and I am having performance issues, can you please suggest any better approach? I understand REGUP is a huge table.

Thanks,

Raj
