How to use the case Statement in SAP
The case statement performs a series of comparisons. Syntax for the case Statement
The following is the syntax for the case statement.
case v1.
when v2 [ or vn ... ].
—
when v3 [ or vn ... ].
—
[ when others.
--- ]
endcase.
where:
* v1 or v2 can be a variable, literal, constant, or field string.
* — represents any number of lines of code. Even zero lines are allowed.
The following points apply:
* Only statements following the first matching when are executed.
* when others matches if none of the preceding whens match.
* If when others is not coded and none of the whens match, processing continues with the first statement following endcase.
* Expressions are not allowed.
* Field strings are treated as type c variables.
Case is very similar to if/elseif. The only difference is that on each if/elseif, you can specify a complex expression. With case, you can specify only a single value to be compared, and values are always compared for equality.
