INTRODUCTION

In this blog I would like to share my views on an error in “PREP_EXTENSION/EHP_INCLUSION” phase in Configuration while working on SUM for converting EHP to S/4Hana.

Overview

SAP has come up with a bigger upgraded version for ERP called SAP Business Suite 4 HANA (SAP S/4HANA) with core capabilities and higher performance.

In the process of S/4HANA Upgrade / Conversion / Migration from ERP 6.0 EHP 8 to S4HANA 1809 using tool SUM 2.0 SP03 PL-9 highlighting an error occurred at Configuration Phase in “PREP_EXTENSION/EHP_INCLUSION”

Error due to mismatch of component version maintained in the source system.

Main Activity

1. In the below screen it declares that the component “SCEMSRV” is not compatible for upgrade / conversion, so this component will be uninstalled during the SUM upgrade.

(SAP Note 2531823 describes how to uninstall the component version from the system.)

2. Below screen-shot describes about the error in detail.

As in a general conclusion, it describes the stack file generated is not equivalent to the source release in system.

However, the system status display’s that both the stack file and component version in the system are different, which is why error displayed (as shown above).

• System’s Status

• Component entry in “stack.xml” File

Now both the numbers of component version for “SCEMSRV” looks different, so now we tried to edit the stack file with correct component details and re executed the configuration phase at point where it has been stopped.

• After editing the field value to 920, repeat the SUM process where it has ended with error earlier.

Conclusion

By changing the stack file with correct component version resolved the error.
