OB08 has no rate for today. Why does the foreign currency document still post?
In SAP documentation the valid rate is one entered on that date or earlier, so with no row for today a foreign currency document still posts if an earlier type M rate exists. Using a fictional invoice, this note calculates how the amount changes with posting and translation dates, then covers quotations, rates entered by hand and how to find stale rates, based on the S/4HANA 2025 documentation.
Checking authorizations in Z programs: what slips through if you only test sy-subrc 4 after AUTHORITY-CHECK?
With only IF sy-subrc = 4 after AUTHORITY-CHECK, a user who was never given the authorization object (sy-subrc 12) passes straight through. Using a fictional Z report, this note covers what sy-subrc 0, 4, 12 and 40 mean, four cases where a 0 does not mean this user is authorized for these values, the places with no implicit check that you must guard yourself, and the order to follow in a review.
When you set the S/4HANA conversion date, must Asset Accounting wait for year-end?
From the Asset Accounting point of view, an S/4HANA conversion does not have to happen at year-end. What it needs is a single open fiscal year at the time of the migration and a complete period-end closing right before installation. Using three candidate dates for the fictional company code BX01, this note shows when two fiscal years are open and what to finish before SUM starts: the last AFAB run, RAPERB2000 and update terminations.
The SI-Check shows red messages. Must you fix every one before converting to S/4HANA?
Red SI-Check messages are not all the same. Return code 7 is an error you read and exempt; 8 and 12 are inconsistencies to solve before the conversion. Based on the Conversion Guide for SAP S/4HANA 2025, this note explains why a yellow 4 is a task list and what SUM stops on at the start and just before the downtime.
You opened the period in OB52. Why is the document still blocked?
A document meets the period check at two points: on row + at the header and on the account type row when an account is entered, and interval 1 can carry an authorization group. Using a fictional variant, this note follows where a document stops and where to look outside OB52, such as the CO lock and ledger groups, based on the S/4HANA 2025 documentation.
ECC mainstream maintenance ends in 2027. Does ECC stop working in January 2028?
Mainstream maintenance for the SAP Business Suite 7 core applications ends at the end of 2027, but what changes that day is the support level. From SAP's public documents, this note lays out extended maintenance at a premium of two percentage points, the automatic move to customer-specific maintenance and the 2031 transition option that is not a maintenance extension, and names three values to read from your own system first.
In S/4HANA, Why Does Code Reading BSIS Still Work While Code Writing to It Must Change?
With the universal journal, totals and index tables such as BSIS became compatibility views with the same name, and reads on tables such as COEP are redirected to differently named views. Based on the 2023 Simplification List, this note explains why the compatibility views serve SELECTs while INSERT, UPDATE, DELETE and MODIFY have to change in custom code.
Is a Z Program with No SCMON Record Really Unused?
SCMON records which ABAP code was called and in what context, and SUSG aggregates that data before it is deleted. Using a fictional example, this note shows why a program that runs only at year-end looks unused in a short recording window, and the order SAP recommends from usage data to deletion.
Code Inspector and ATC Warnings: How Is Hiding One in Code Different from an Exemption?
Code Inspector pairs what to check with a check variant, and ATC can run checks at three gates, during development, at transport release and in central checks, with each run using a global Code Inspector check variant. This note compares pragmas and pseudo comments, which hide a warning in the source, with exemptions, which need a quality manager's approval: what each covers, where it lives and who decides.
Is the SAP Object Your Z Program Uses a Released API?
A released API is an object with two classifications, a release contract and a visibility. Using T005 and I_COUNTRY as the example, this note shows how to check an SAP object's release state in ADT's API State tab and in SAP's public Cloudification Repository, and why Z code that relies on unreleased objects becomes a burden at upgrade time.
What Do SPDD and SPAU Adjust During an Upgrade?
An update overwrites SAP objects with the delivered versions, and your modifications with them. Using a fictional example, this note shows what SPDD and SPAU reconcile with the new standard, why SPDD comes first, and how changes made with and without the Modification Assistant differ at adjustment time.
Where Does a Z Program Need Fixing When S/4HANA Widens the Material Number Field to 40 Characters?
Since release 1511, SAP S/4HANA has widened the material number field from 18 to 40 characters, yet the extended material number functionality starts out switched off. Z code may still need changes. Based on the 2023 Simplification List and the ABAP keyword documentation, this note looks at three places: fields with a hard-coded length, keys built by concatenation, and released interfaces called within the system.
