Expression Positions in Release 7.0, EhP2
1 Using functions and expressions
2 Method chainings
3 Predefined functions with multiple arguments
Latest notes: The program DEMO_EXPRESSIONS
shows examples of the enhanced expressions in Release 7.0,
EhP2 .
ABAP_MODIFICATION_1
The usability of functions and expressions in operand positions has been substantially improved in Release 7.0, EhP2 :
Calculation expressions , predefined functions , and functional methods can be used in general expression positions .
Numerical expressions can be used in numerical expression positions .
String expressions can be used in
character-like expression positions .
Functional methods can be used in functional operand positions .
From Release 7.0, EhP2 , the following general expression positions are available:
Operands of relational expressions
Example: a + b oref- meth( )
Actual parameters for input parameters of methods
Example: oref1- meth1( oref2- meth2( ... ) )
Before Release 7.0, EhP2 , operand positions on the right side of assignments with = were the only general expression positions.
Latest notes: From EhP1 , the character-like arguments of description functions are (with one exception) character-like expression positions . Before EhP1 , they were character-like functional operand positions .
ABAP_MODIFICATION_2 Method Chainings
As well as the previous chained names ,
operand positions that accept functional methods now also accept
method chainings , that is chained method calls and chained attributes accesses .
ABAP_MODIFICATION_3
Release 7.0, EhP2 introduces new
predefined functions that can now accept multiple arguments. A predefined function of this type is called in the same way as a functional method with multiple input parameters.
... func( p1 = arg1 p2 = arg2 ... ) ...
The new functions are include:
Rounding functions
Search ,
similarity , and processing functions for character strings
Logical functions
