Select for all entries

When you need to access many records from one internal table is better to use select for all entries.

instead of doing this

loop at internal-table

select * from table where…….

endloop.

it’s better to

FOR ALL ENTRIES IN it_vbrk

WHERE bukrs = it_vbrk-bukrs

AND blart = ‘DV’

AND xblnr = it_vbrk-doc

AND bstat = ”.

This way you will have one select to all the entries in it_vbrk.
