What changes in S/4HANA

Material master structure changed significantly in S/4HANA (new fields, reorganized data).

Before and after: ABAP code example

Before (ECC) 
* ECC: MARA/MARC direct read with SELECT *
SELECT a~matnr a~mtart a~mbrsh c~werks c~minbe
  FROM mara AS a
  INNER JOIN marc AS c ON c~matnr = a~matnr
  INTO TABLE @DATA(lt_mat)
  WHERE a~mbrsh = @lv_industry.
After (S/4HANA) 
* S/4HANA: released CDS view I_MaterialPlant
SELECT material, materialtype, industrysector,
       plant, minimumstocklevel
  FROM i_materialplant
  INTO TABLE @DATA(lt_mat)
  WHERE industrysector = @lv_industry.

Effort estimate and common pitfalls

Effort estimate

M — Medium (days)

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

  • ! Missing related objects that contain the same pattern
  • ! Not testing edge cases after replacing the API
  • ! Skipping regression tests for dependent programs

Related rules to check

HIGH S

SELECT * usage

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

VBAK/VBAP direct access

Direct reads from VBAK/VBAP (Sales Document header/item). S/4HANA adds fields that change the structure.
HIGH M

EKKO/EKPO direct access

Direct reads from EKKO/EKPO (Purchase Order header/item). Use released API I_PurchaseOrder.
