inner join (multiple tables access)

[former_member649905]

Hi Experts,

Could you pl look into the code and let me now what that inner join is doing? I am thinking that data from all tables AFKO, AFVC, MSEG, EKBE, ESLL, T430 are selected and extracted but someone told me without further explanations that data are extracted only from AFKO, AFVC. From MSEG, EKBE, ESLL the join is only doing a validation check and I am not understanding that.

Below is the code.

Hi Blaiso;

I dont know Why did use this method? Because this method not healthy and has more performance problem.

If you want to more performance you add some index to tables.

If you want to "Correct Result", You must know tables relation between tables, according to your specific scenario.

I suggest to you, use loop method and itab at this status.

You can examine bellow way

Hi Melih,

Thanks for replying, this program fetch online data (in R/3) and pass them to the setup tables for BW. Now certain tables (in R/3)would be archived based on archiving like PS_Project, MM_Matbel...

Generic datasource need to be put in place in case archived data + online data may need to be load (full load) to BW.

Archived data are indexed using PBS functionality

I would like to now exactly from which tables(with explanation please), data are extrated on that program.

Regards.
