Video Lesson 4.8: ABAP IF statement and CASE

Planning to get your own website? The first step is to get a Wordpress-friendly hosting service with excellent customer service. I recommend Bluehost. Follow this link to learn more.

This lesson shows how to use the IF statement and the CASE statement for conditioning.

In ABAP you have two ways to execute different sequences of statements, depending on certain conditions:
In the IF construct you can define any logical expressions as check conditions.
You can use nested IF statements, using the ELSEIF clause.
You can use the CASE construct to clearly distinguish cases.
The content of the field specified in the CASE part is checked against the data objects listed in the WHEN branches to see whether they match.

In both constructs the condition or match check happens sequentially from the top down.
As soon as the statement block of a branch has been executed, the system immediately jumps to ENDIF or ENDCASE.
