How to use Maintenance Planner for S/4 HANA Conversion

Introduction

In previous blog of S/4 HANA adoption we learnt about what all options to adopt the S/4 HANA and started discussing about the option of system conversion.

As discussed earlier, the system conversion option is available for such customer who wants to convert their current system into an SAP S/4 HANA system

Let’s quickly go over the high level plan for S/4 HANA conversion project as shown below,

Maintenance Planner:

The first step in S/4 HANA conversion is to analyse the source system using the Maintenance planner tool.

When you open the SAP Maintenance Planner for your system landscape you will see below screen with the list of available systems under “Explore Systems”.

Select the system from the list which you are planning for S/4 HANA conversion

In this case I am selecting the system EC1 which got some errors in verification and data sync with Solution Manager

The sync errors are resolved by ignoring the software components as these components are not present in my source system and can be ignored

After rectifying all the errors my system is ready for planning the S4 HANA conversion

Start the Planning activity as shown below,

This is the benefit of running maintenance planner at the start of S/4 HANA conversion project. At start of the project you will come to know if your system is ready for conversion or not and what all things which needs to be completed before system made ready for S/4 HANA conversion

As per below error screen, there are certain add-ons and business functions available in my system which are not supported by S/4 HANA and these issues needs to be addressed before we can select the S/4 HANA conversion

Check SAP note 2214409 and 2011192 for further details on how to handle the non-supported add-ons for S/4 HANA

I am able to resolve all the dependency and made sure the business functions information is available in solution manager so that it will be selected during the conversion process

After rectifying the above error the system is ready for the S/4 HANA conversion project

It’s very important to resolve the add-on errors as all the add-on's are not supported by S/4 HANA. Also, this is very important step as part of early planning in S/4 HANA conversion projects as it will give clear understanding in terms of if your environment is eligible for conversion scenario or you need to go for new Implementation and then do the data migration/conversion

Note: Solution manager plays very vital role in S/4 HANA conversion projects and it’s very important to have Solution manager properly setup and right data is sync between source system and solution manager
