Expression Positions in ABAP Release 7.0, EhP2 ITOC
Latest notes: The program DEMO_EXPRESSIONS shows examples of the enhanced expressions in ABAP_RELEASE 7.0, EhP2. ABAP_HINT_END
ABAP_MODIFICATION_NN Using Functions and Calculation Expressions
The usability of functions and expressions in operand positions has been substantially improved in ABAP_RELEASE 7.0, EhP2:
Calculation expressions, built-in functions, and functional methods can be used in general expression positions.
Numeric expressions can be used in numeric expression positions .
String expressions can be used in character-like expression positions.
Functional methods can be used in functional operand positions. From ABAP_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 ABAP_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_HINT_END
ABAP_MODIFICATION_NN 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_NN Access to Components of Structured Return Values
If the result of a functional method or method chaining is structured, the call can (like the name of a structure) be written directly in front of the structure component selector to access a component of the result.
ABAP_MODIFICATION_NN Built-In Functions with Multiple Arguments
ABAP_RELEASE 7.0, EhP2 introduces new built-in functions that can now accept multiple arguments. A built-in function of this type is called in the same way as a functional method with mult iple input parameters. ... func( p1 = arg1 p2 = arg2 ... ) ... The new functions are include:
Rounding functions
Search, similarity, and processing functions for character strings
