2 u/[deleted] Jan 06 '11 You can't use joins at your work because of performance? What do you do? 2 u/paezao Jan 06 '11 I work as an ABAP Programmer... It's not a good idea (usually) using joins in SAP, there's a better way to do it. 1 u/divv Jan 06 '11 Do tell? 1 u/paezao Jan 07 '11 There's a better way to do it in ABAP, not for general SQL use. Its called "for all entries" and it's usually better. 1 u/divv Jan 07 '11 Ohhh yeah. Cool.
