System table to identify BEx Query?

We have request to provide report on Query Change info, for example. This data is available when manually going into each query, however we need to see this in a single view, rather than opening every query via BEx Query Designer.

We need the following:

Query Name

Last Changed Date

Time

User

Need to know system tables to browse or other way to provide this info. Have found <u>some</u> data in RSZ tables, however date/time is unreadable.
