🚀 Why This Series?

Traditional ABAP was verbose and repetitive. But now, SAP’s newer syntax allows you to write concise, elegant, and type-safe code using inline expressions and powerful new operators.

🧠 If you're still using READ TABLE, CREATE OBJECT, or CONCATENATE, it's time to upgrade.

Let’s explore the highlights.

✅ Inline Data Declaration

Old Way:

DATA lv_value TYPE i.
lv_value = 1.

New Way:

DATA(lv_value) = 1.

🎯 Why It Matters: Clean code, less typing, and automatic type inference.

✅ Table Expressions – Bye Bye `READ TABLE`

Old:

READ TABLE lt_vbak INDEX 1 INTO ls_vbak.

New:

ls_vbak = lt_vbak[ 1 ].

⚠️ Wrap in TRY...CATCH to avoid dumps if index/key doesn’t exist.

✅ Table Read with Key

ls_vbak = lt_vbak[ vbeln = '0000000001' ].

Clean, one-liner key access. No need for sy-subrc checks!

✅ Safe Access with `OPTIONAL` & `line_exists`

ls_vbak = VALUE #( lt_vbak[ vbeln = '123' ] OPTIONAL ).

IF line_exists( lt_vbak[ vbeln = '123' ] ).
  ls_vbak = lt_vbak[ vbeln = '123' ].
ENDIF.

✅ COND – Replace IF Chains

DATA(priority) = COND string(
  WHEN lv_value < 10000 THEN 'Low'
  WHEN lv_value <= 20000 THEN 'Medium'
  ELSE 'High'
).

Elegant, readable condition-based assignment.

✅ SWITCH – Value Mapping Made Clean

DATA(result) = SWITCH string( lv_type
  WHEN 'A' THEN 'Inquiry'
  WHEN 'B' THEN 'Quotation'
  ELSE 'Others'
).

✅ Type Inference with `#`

DATA(lv_grade) = COND #( ... ). " Type inferred
DATA(lt_ids)   = VALUE #( ( 1 ) ( 2 ) ).

Let ABAP guess the type when the context is clear.

✅ Modern String Handling

DATA(lv_str) = |{ lv_first } { lv_last }|.

Replace CONCATENATE, simplify string building.

✅ ALPHA Conversion Inline

DATA(lv_kunnr) = |{ '123' ALPHA = IN }|.
DATA(lv_disp)  = |{ lv_kunnr ALPHA = OUT }|.

Say goodbye to CONVERSION_EXIT_ALPHA_INPUT.

✅ CORRESPONDING – Auto-Map Fields

ls_target = CORRESPONDING #( ls_source
  MAPPING field1 = source_field1
  EXCEPT field2
).

Simplifies field mapping between structures and tables.

✅ CONV – Clean Type Conversion

DATA(lv_int) = CONV i( '123' ).

Use in VALUE, REDUCE, or even table initialization.

✅ VALUE – One-Liner Table Creation

DATA(lt_emp) = VALUE tty_emp(
  ( id = 101 name = 'Amir' )
  ( id = 102 name = 'Malkani' )
).

✅ BASE – Update Without Rewriting

DATA(ls_new) = VALUE ty_emp(
  BASE ls_old
  name = 'Updated'
).

✅ NEW – Object Instantiation in One Line

DATA(lo_car) = NEW zcl_car( iv_model = 'BMW' iv_year = 2024 ).

✅ FILTER – Elegant Table Filtering

DATA(lt_filtered) = FILTER #( lt_emp WHERE id = 102 ).

Supports IN, EXCEPT, and WHERE filtering styles.

✅ LET ... IN – Scoped Variables

DATA(ls_emp) = VALUE ty_emp(
  LET first = 'Amir' last = 'Malkani' IN
  full_name = |{ first } { last }|
).

✅ REDUCE – Powerful Looping

DATA(sum) = REDUCE i(
  INIT x = 0
  FOR i = 1 THEN i + 1 UNTIL i > 5
  NEXT x = x + i
).

Replace DO, LOOP, and accumulators with readable expressions.

✅ Modern Open SQL

SELECT vbeln, erdat INTO TABLE @DATA(lt_vbak)
  FROM vbak WHERE vbeln IN @s_vbeln.

Use @DATA, inline declarations, and comma-separated fields.

✅ SELECT with Literal – Existence Check

SELECT SINGLE 'X' INTO @DATA(lv_exists)
  FROM vbak WHERE vbeln = '123'.

Clean way to check if a record exists.

✅ Aggregate Functions

SELECT SUM( netwr ) INTO @DATA(lv_total)
  FROM vbak WHERE vkorg = '1000'.

Native support for SUM, COUNT, AVG, MIN, MAX.

🔚 Conclusion: Write Clean, Modern ABAP Today

Modern ABAP syntax is not just syntactic sugar — it’s a productivity booster, a readability enhancer, and a best-practice enabler.
