Getting started with the S/4Hana Migration Cockpit (OnPremise)

Overview

The S/4HANA Migration Cockpit is available from S/4HANA Release 1610 in the OnPremise Version.
As it is the first Version, i don’t have too much expectations, but i am sure we will see very interesting updates in the future.
Basically, it is a Web Based Tools to migrate Legacy Data into S/4HANA. It allows to Download predefined Excel Sheet-Templates, so you can “easily” extract legacy data into this format and upload in S/4HANA by using the Migration Cockpit. Basic Mapping Functionality is provided (e.g. Map Unit of Measure Codes and so on) but don’t expect too much here yet.
Target group seems to be smaller and medium businesses (SMB). The handling of the Import Process and Validations are made very easy (“cloud style”)
To Import the Data, the SAP Standard BAPIs are used. There is an error Log provided with information on Warnings or Errors.
As there is already a number of Standard Objects Available (see below)

Migration Process

In the first Screen you can create or open a Migration Project.


then you can activate one or multiple migration objects



Now Open the Migration Object

you can look at the documentation of the migration object

you can Download an Excel Template.

Now fill the Excel with you data


and Upload into the Migration Cockpit


select and activate the File


now start Transfer (migrate to S/4 Hana):
First the Data is validated


when finished 100 %, click on close

now you can see the notifications (warnings/error messages):

Choose next to perform the Value Mappings (Convert Values)


if a value from the excel sheet is found for the first time, you have to confirm or add a value mapping:

enter a new Value (EV_xxx) and/or click on confirm


now click on next for the simulation and then next for the import (same procedure as validation)

all actions are performed in background (as a batch-job/SM37), but you can wait until process is finished 100 % and then immediately see the results or let it run in background and come back later.

Excel Format

The Excel Templates are in XML Format

it looks like this

i faced problems with ‘SPACE’ for empty columns, they should be <null> otherwise the ss:Index gets confused and the Values are linked to the wrong columns when importing into the migration cockpit, even if they are in correct order

Import Processing

It helps if you are familiar with the Standard BAPI Structures and SAP Input Data (for example how to create a material master)
Abap Skills are not required, but ABAP Debugging skills are useful for the Root Cause Analysis in cases where the Error Log isn’t enough.


The BAPI used for the Data Inport can be found in Transaction LTMOM

you can also see how the input fields are mapped.
currently i was not able to change the standard mappings, i can only add customer fields.

you can set an external Breakpoint (external as the import is always performed by a batch job)

here you can also save the data (after mapping/conversion) as testdata for SE37 (right click on toolbox)  if you need to do some troubleshooting

in some cases i added an ‘implicit enhancement’ at begin of function (ABAP Enhancement Concept) in the importing BAPI to change the conversion.
(quick and dirty?)

Generated ABAP Objects

The Migration Cockpit generates ABAP Function Modules for the Conversion and the Import.
These can be Debugged (or maybe even “enhanced”?)
if you come from LSMW or other ABAP Migration Tools you will find yourself familiar shortly.

further Tips

Structure XXXX: Number of recipient records generated 0000000000 (or less than in input file)
reason:
the Migration Cockpit is storing all created objects in Table DMC_FM_RESTART, so if your object number, for example material number, is in this table, it will be skipped and not imported again.
you can delete the entry with transaction code se16


also if a job with the name /1LT/LOAD… is scheduled or already running, the import will not start
(but shows no error message)
verify with SE37
Check from ABAP Coding
START_DATA_LOAD (CL_DMC_WDA_MIG_CONTR) CHECK cl_dmc_act_rec=>get_active_and_scheduled_jobs( iv_ext_id        = lv_ext_id
iv_activity_type = cl_dmc_act_rec=>…

Export Data from R/3 Source System? in the online help there is a remark: In the ABAP-based SAP source system, you have installed the DMIS add-on. You can download the add-on from the SAP Software Download Center at http://support.sap.com/swdc using the following path: Installations and Upgrades  A – Z Index  L  SAP LT Replication Server  SAP LT Replication Server 2.0 .
how can i export the data for the Migration Cockpit?

Best-Practice how to fill the Excel/XML Files with legacy data

The Excel-Templates are very nice, Examples with Best-Practice Data would help understanding how to fill the values.

how to create Additional Mapping Rules like we know this from LSMW?
Create Additional Migration Objects

Create Contact Persons for Customers (i could assign them to the Customer, but i had to to a workaround to create the Contact Person’s Business Partner Number)

Mass/Data, Performance, parallel Processing, memory consumption, limitations…

strangely i could not find any oss notes, nor any blogs, is nobody using the tool yet?

so maybe i will write another Blog…
