Hi

Defintely LDBs will increase your performance.

All the tables you are using have the relation then you can create the LDB and use it in your program. Genrally we use LDBs for Dynamic selection screens.

I think , it depends. if the report requires several fields from various DB tables with complex calc then LDB's increase the performance. I have seen simple reports where LDB's didnt increase the performance due to features as automatic text recognition etc.. which is an overhead ..
