How find Actuate table

[sys2674]

Hi I am new to Actaute,
I have acess to reports and need to modify the reports.
Can any one tell me from where to i get the tables names and logics used for a report
I went to the properties of each component and then it assumed to be temporary file names.
so i searched in .bas file and there are job id's i ran a select stamt got almos 89 macros..do i search all the 89 macros for the table names.

there are two reasons why i need the table names for the
1. to modfy the actuate reports
2. need to pull those tables in cognos and create a report out of it.

Thanks
