How to remediate: VBAK/VBAP direct access

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

What changes in S/4HANA

Use released CDS view I_SalesDocument. New fields in S/4HANA can cause issues with SELECT * or positional field access.

Before and after: ABAP code example

Before (ECC) 
* ECC: direct VBAK/VBAP read with SELECT *
SELECT * FROM vbak AS h
  INNER JOIN vbap AS i ON i~vbeln = h~vbeln
  INTO TABLE @DATA(lt_so)
  WHERE h~vkorg = @lv_vkorg
    AND h~auart = @lv_auart.
After (S/4HANA) 
* S/4HANA: released CDS view with explicit fields
SELECT salesorder, salesorderitem, material,
       requestedquantity, netamount
  FROM i_salesorderitem
  INTO TABLE @DATA(lt_so)
  WHERE salesorganization = @lv_vkorg
    AND salesordertype    = @lv_auart.

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.
CRITICAL XL

BSEG direct access

BSEG is a cluster table in ECC. In S/4HANA, financial data moved to ACDOCA (Universal Journal).
HIGH M

EKKO/EKPO direct access

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