You can do that...

Use the function module LDB_PROCESS.

This allows you to use the logical database as a routine for reading data. You can call more than one logical database from the same program. You may also call the same logical database more than once from the same program.

When you call a logical database using the function module LDB_PROCESS, its selection screen is not displayed. Instead, you fill the selections using the interface parameters of the function module.

The logical database does not trigger any GET events in the calling program, but passes the data back to the caller in callback routines.

Calling a logical database using LDB_PROCESS thus decouples the actual data retrieval from the preceding selection screen processing and the subsequent data processing.

Hope this helps.

Hi,

You cannot use two LDBs in one program irrespective of any module. Use one LDB and write select statement for the rest of required tables.
