S/4HANA 1809: Custom Code Migration with new Fiori

The S/4HANA Custom Code Check is supporting the analysis of you Custom Code and to identify if there are Simplifications applicable to your Custom Code, in order to make it run on S/4HANA.
This is done using ATC.

(Further References on ATC:

https://blogs.sap.com/2017/02/15/sap-s4hana-system-conversion-custom-code-adaptation-process/ )

ATC has 3 possible ways to work with:
a) GUI
b) ADT ABAP in Eclipse
c) since S/4HANA 1809 there is a nice new Fiori Application

you can start ATC on the newest S/4HANA 1809 System and do a remote analysis on your connected R/3 System
This Blog is about how to work with this new Fiori.
Preparation:

1. Create PFCG Role for Fiori Catalog and assign to Userhttps://help.sap.com/viewer/9a281eac983f4f688d0deedc96b3c61c/201809.000/en-US/34f67edd5f3e4c1eb00ad1943f551fb8.html?q=App%20Implementation:%20Custom%20Code%20Migration For required Authorizations also check SAP Note 2672703 
   Now add the tile by using the App Finder to my Home:

(Description is wrong here but implementation information is still correct)

The ICF nodes for the following SAPUI5 application must be activated on the fron

t-end server:

Component	Technical Name	Path to ICF Node	SAP UI5 Component
SAP UI5 Application	NW_APS_CCM_PRJ	/sap/bc/ui5_ui5/sap/nw_aps_ccm_prj/	CcmProjects
SAP UI5 Application	NW_APS_EXT_LIB *	/sap/bc/ui5_ui5/sap/nw_aps_ext_lib
SAP UI5 Application	NW_APS_LIB *	/sap/bc/ui5_ui5/sap/nw_aps_lib

ODATA Services:

SYCM_APS_C_ATC_FIND_ALP_CDS	0001
SYCM_APS_C_PROJECT_CDS	0001
SYCM_APS_C_SCP_BY_EP_CDS	0001

2. Setup prerequisites for ATC
this process is the same as for Eclipse, please also see link to Documentation Custom Code Migration
the minimum is to have a RFC Destination to connected System (can also be the same system instead of remote)
there is no need to run any ATC Jobs, this will all be done from the Fiori.
i had to re-load the Simplification Item Database in /NSYCM according to SAP Note 2532285 – ATC: Inspection was not executed because target release information cannot be processed. (otherwise it always told me no target release information available as a finding)

Start the Fiori:
Now Start the Fiori Tile ‘Custom Code Migration’ from the Launchpad:

1. Create Custom Code Migration Project:

choose the Target Release and RFC Destination:

2. Run the Analysis
you can refresh the status, this might take some time (you can also see Batch Job in /NSM37)

3. Analyze the results
if the Job is finished, go to the ‘Analysis’ Tab.

it’s a really fast & nice Fiori Application with all the new Fiori Elements functionalitys for Filters/Charts etc:
you can select by object type or simplification item note:




click on Analyze Findings:


have fun!
