Conversion to S/4HANA 1809FPS0 – t5 – Custom Code Migration

This blog is for the detailed steps for Custom Code Migration (CCM) for step t5 of conversion to S/4HANA 1809FPS0 is an optional step. The steps are shown for Custom Code Analysis to estimate efforts required for the Custom Code Adaptation. As part of custom code migration there is also a step to be done after the system conversion in SPDD/SPAU.

STEP 1: Apply Notes in the Checked System. The checked system can have either of Software components – SAP_BASIS 7.00, 7.01, 7.02, 7.31, 7.40, 7.50, 7.51 or 7.52.

TIP: First 2 notes are huge and if you get “Note Incomplete” or “Error occurred while downloading 
SAP Note xxxxx” please try downloading again individually and if it still doesn’t work, download 
from launchpad /upload in snote manually. To give you an idea of size – 2485231 is 4MB , 2270689 is 11MB, 
2190065 1.6MBis and 2196792 is 1MB

Apply Note 2485231 – Remote ATC Checks of Modifications and Enhancements

Create Function Group SCA_ABAP_CHECK_MODINFO

Get Access Key

Checkmark Confirmed and continue – 2 times

Check and set as below:

Create Function Group SCA_REMOTE_DATA_ACCESS

Checkmark on Copy Changes for first 2 items

Click on Activate Anyway

Apply Note 2270689 – RFC Extractor for performing static checks

This note is HUGE and you may face errors while downloading. Try downloading the note from browser and then upload in SNOTE.

Create Function Group SABP_COMP_PROCS_E

Activate the function group SABP_COMP_PROCS_E.

Checkmark on Copy Changes for first 2 items

Click on Activate Anyway –  6 times

Start Report RS_ABAP_INIT_ANALYSIS and Confirm step.

Apply Note 2190065 – ATC/CI: Remote Code Analysis – Object Provider Stub

This note was already implemented by other notes.

Apply Note 2196792 – RFC-Stub for CVA/SLIN-Remote

Under package SLIN, create subpackage S_CVA_BSP

Under package SLIN, create Function Group SLIN_REMOTE_RESOURCES

Activate Function Group SLIN_REMOTE_RESOURCES


Activate Function Group CVA_BSP_REMOTE_RESOURCES

The object tree should look like this:

Checkmark on Copy Changes for first 3 items

Create a user in Checked system with below authorizations. like CCM_CHECKED.

This completes the steps for the Checked system.

STEP 2:  The Central Check system should have Software component SAP_BASIS 7.52 or higher. In case you already have a S/4HANA sandbox, you could use it. Also you can use a S/4HANA Fully activated Appliance on-prem or in CAL, it just requires Netweaver 7.52.

We will use CAL solution which is SAP NetWeaver AS ABAP 7.52 SP01 on SAP ASE 16.0 from below:

Below config is fine to reduce cost.

Activate Instance and login as user DDIC, copy user DDIC to create user S4HCONV so notes can be applied. Ensure RFC SAPOSS is configured and working.

The 2 notes are not to be applied in Checking system using SNOTE but contain information related to notes which are to be applied.

Apply Note 2436688 – Recommended SAP Notes for using SAP S/4HANA custom code checks in ATC

Since this is a Netweaver 7.52 SP1 system we have to apply the notes:

2578127 – Pseudo comments for S/4HANA custom code checks
2577440 – Improvements in S/4HANA custom code check “S/4HANA: Search for S/4 related syntax errors”
2569135 – S/4HANA custom code check “S/4HANA: Search for S/4 related syntax errors” reports syntax warnings
2573527 – S/4HANA custom code check for buffered DB table access

All above notes do not have manual steps.

Apply Note 2364916 – Recommended SAP Notes for using ATC to perform remote analysis

This second note states must apply below note for Netweaver 7.52 SP1

2375392 – Downport of Code Inspector remote checks

Above note does not have manual steps.

Now note 2364916 states that we must apply the 4 notes as already done in step 1. In addition the note states you can also apply following notes in checked system depending on your SP. Thy all turned out to be in status “cannot be implemented”.

2381403 – Infrastructure for remote checks
2375864 – ATC: Remote Checks – Developer Scenario
2587593 – ATC: Checkability of Modifications and Enhancements in Remote Checks – Developer Scenario
2614006 – ATC remote check fails in developer scenario

STEP 3:  Download the CCMSIDB from Service Marketplace.

Import the Simplification Database into Central Checking System

enter tCode SYCM

After clicking Open, there is a message Loading ZIPC:\CCMSDB00P_7-8000101. The  there is a message – Downloading simplification notes ….

You should get message below:

You can now display the content of the simplification database. Click the Overview button.

If you click on Show Items for Selection, you can view the Simplification Database content with displayed list by SAP Object Type, Simplification Category and relevant SAP Note Number.

STEP 4:  Set the role of the Cental Check Systsem

Enter tCode ATC => System Role => Change System Role

Create System Groups tCode ATC => ATC Administration => Setup => Object

Enter tCode SM59, create RFC destination, Connection Type 3  in the Checking system to point to the checked system.

Create RFC Object Providers tCode ATC => ATC Administration => Setup => Object Providers

STEP 5:  Apply Note 2659194 – Check variant for SAP S/4HANA 1809 custom code checks

Run the ATC Checks from Central Checking System

Configure remote ATC runs series tCode ATC => Runs => Schedule Runs , Create CONV1

Select Check Variant S4HANA_READINESS_1809 and Save the configuration.

Schedule a Remote ATC Run series

Select the run series and click Schedule button on toolbar.

Analyze ATC Run Results

tCode ATC => ATC Administration => Runs => Manage Results

  1. In the navigation pane in transaction ATC, expand the nodes ATC Administration Runs and double-click Manage Results.
  2. Leave the run series field empty and choose Execute (F8).
  3. In the ATC Manage Results view is displayed. The view shows a list of ATC run results from your requested period of time. A list of all ATC findings is displayed in transaction SE80.
  4. Choose Statistics View
  5. In the ATC Manage Results view, select a run series and choose Display to inspect the results.
    Choose Statistic to group the ATC findings (for example, by SAP Note Number).
    The ATC findings are grouped by the selected statistics
  6. Double-click a statistics group to display the list of ATC findings assigned to the selected statistics.
  7. Double-click an ATC finding to open detailed information. Here you can find the SAP Note number referring to a dedicated SAP Note and the referenced object.
  8. Click the object name to navigate to the source code to see where the incompatible code occurs
