Sample code and senarios to use outer join?

[Former Member]

We know the ABAP4 syntax for inner join, but never tried outer join and we even don't know if there is any outer join syntax in ABAP4 or not. Would be very appreciated if some ABAP expert here let us know if there is any outer join and list the difference between inner join and outer join with detailed senarios or when we would use outer join or when to use inner join? Also give a sample code on the outer join if there is any in ABAP?

Thanks and we will give you reward points!

Hi Kevin,

Yes there is OUTER JOIN syntax in ABAP. Just do F1 on keyword OUTER JOIN you will get sample code.
