What changes in S/4HANA

ABAP Cloud restricts language and object use to released APIs. Unreleased objects cause syntax errors in strict mode.

Before and after: ABAP code example

Before (ECC) 
* ECC: internal FM without C1 release — blocked in ABAP Cloud
CALL FUNCTION 'SLIN_INTERNAL_CHECK'
  EXPORTING object = lv_object
  IMPORTING result = lt_result.
After (S/4HANA) 
* S/4HANA ABAP Cloud: use only C1-released APIs
* Check release status via: CL_ABAP_TYPEDESCR or SE80 release flag
* Replace with equivalent released class method:
cl_abap_unit_assert=>assert_not_initial(
  act = lt_result ).

Effort estimate and common pitfalls

Effort estimate

L — Large (1–2 weeks)

Estimate is per affected object. Total effort scales with the number of occurrences in your codebase. Use the A1 scan to get an object-level count before estimating the full project.

Common pitfalls

  • ! Underestimating the number of affected objects
  • ! Missing performance test after switching to released APIs
  • ! Transport dependencies across development, quality, and production

Related rules to check

MEDIUM M

Obsolete function modules

Usage of function modules flagged as obsolete in SAP S/4HANA simplification list.
HIGH S

SELECT * usage

SELECT * reads all columns including new S/4HANA columns, causing unexpected results and performance issues.
MEDIUM S

Hardcoded client/system fields

Hardcoded MANDT, client numbers, or system IDs. Breaks in multi-client and cloud scenarios.
