1.
Inline Declarations
ABAP 7.4
Introduced inline declarations using DATA(...) for variables directly in expressions.
Example:
abap
Copy code
LOOP AT lt_table INTO DATA(ls_table).
WRITE: / ls_table-field.
ENDLOOP.
ABAP 7.5
Extended inline declarations to work with FIELD-SYMBOLS(...) and CONSTANTS(...).
Example:
abap
Copy code
LOOP AT lt_table ASSIGNING FIELD-SYMBOL(<ls_table>).
WRITE: / <ls_table>-field.
ENDLOOP.
CONSTANTS(my_const) TYPE i VALUE 10.
2. Constructor Operators
ABAP 7.4
Added constructor operators like VALUE, CONV, and CORRESPONDING to simplify data
handling.
Example:
abap
Copy code
DATA(result) = VALUE string( `Hello ABAP 7.4` ).
ABAP 7.5
Introduced new constructor operator REF for creating references dynamically.
Example:
abap
Copy code
DATA(ref_table) = REF #( lt_table ).
3. String Templates
ABAP 7.4
Allowed embedding variables in strings using |...| templates.
Example:
abap
Copy code
DATA(name) = 'John'.
WRITE: |Hello, { name }!|.
ABAP 7.5
Enhanced string templates with control structures like loops and conditions directly
inside templates.
Example:
abap
Copy code
DATA(count) = 5.
WRITE: |You have { count > 1 ? 'items' : 'item' } in your cart.|.
4. Table Expressions
ABAP 7.4
Introduced expressions to read or modify internal table entries using [].
Example:
abap
Copy code
DATA(value) = lt_table[ id = '001' ]-field.
ABAP 7.5
Allowed dynamic table key specifications in table expressions.
Example:
abap
Copy code
DATA(value) = lt_table[ (dynamic_key) ]-field.
5. New Syntax for Loops and Conditions
ABAP 7.4
Enhanced LOOP with GROUP BY for grouped processing.
Example:
abap
Copy code
LOOP AT lt_table INTO DATA(ls_table) GROUP BY ls_table-category INTO
DATA(group).
WRITE: / group.
ENDLOOP.
ABAP 7.5
Introduced a cleaner syntax for control structures like IF, CASE, and LOOP.
Example:
abap
Copy code
LOOP AT lt_table INTO DATA(ls_table) WHERE ls_table-active = 'X'.
WRITE: / ls_table-field.
ENDLOOP.
6. Enhanced Type Declarations
ABAP 7.4
Allowed TYPES to define table types inline.
Example:
abap
Copy code
TYPES: BEGIN OF ty_structure,
field1 TYPE i,
field2 TYPE string,
END OF ty_structure.
TYPES: ty_table TYPE TABLE OF ty_structure WITH EMPTY KEY.
ABAP 7.5
Introduced the TYPE TABLE OF ... WITH EMPTY KEY syntax for internal tables with no
keys.
Example:
abap
Copy code
DATA(lt_table) = VALUE TABLE OF ty_structure( ).
7. New Control Keywords
ABAP 7.4
No significant changes to control keywords.
ABAP 7.5
Introduced FOR as an iteration expression in constructors and templates.
Example:
abap
Copy code
DATA(lt_numbers) = VALUE #( FOR i = 1 THEN i + 1 UNTIL i > 10 ( i ) ).
8. CDS and AMDP Integration
ABAP 7.4
ABAP 7.4 focused on CDS Views and ABAP Managed Database Procedures
(AMDP).
Example:
sql
Copy code
DEFINE VIEW ZCDS_VIEW AS SELECT FROM scarr
{
key carrid,
carrname
}
ABAP 7.5
Further integrated CDS views with annotations and introduced CDS Table Functions.
Example:
sql
Copy code
DEFINE TABLE FUNCTION ZCDS_FUNC
RETURNS
{
field1 : abap.string(30),
field2 : abap.int4
}
9. Reduced Obsolete Statements
ABAP 7.4
Continued support for many legacy keywords but recommended using modern
constructs.
ABAP 7.5
Marked more keywords as obsolete, encouraging the use of cleaner alternatives:
o Use SELECT ... INTO TABLE instead of SELECT ... APPENDING TABLE.
o Use inline declarations instead of explicit DATA statements.
