Documents related to conversionSAP S/4HANA on SAP Help Portal

Steps in the conversion processMaintenance Planner conversion pre-Checks: Checks your add-ons and business functions to ensure compatibility with SAP S/4HANA. Also creates the stack file used for the actual conversion

Checks the compatibility of add-on software component versions present on a given ERP technical system with SAP S/4HANA.

Checks existence of a valid read RFC destination to the technical system from the SAP Solution Manager in the customer landscape. This is required to retrieve the business function

Checks if there are business functions in the technical system which are not supported in the SAP S/4HANA. The results of this check may vary based on the selected support package

Checks for existence of a connected Java system. If a dependency exists to a Java system, the conversion planning stops and can only continue if the product maintenance dependency

Checks if the note 2186164 is deployed on the SAP Solution Manager. If not applied, the conversion planning is stopped.

Conversion pre-checks: To check the system,

Execute program R_S4_PRE_TRANSITION_CHECKS for targets till SAP S/4HANA 1610.

Execute program /SDF/RC_START_CHECK for SAP S/4HANA 1709 and above targets on the ERP system.

Custom code check tool: Checks your custom code against a list of simplifications developed for SAP S/4HANA. Ideally you perform these checks at the same time as your prechecks

General and application-specific preparations: Manual activities to prepare your system and applications.

Software Update Manager(SUM): Automates the conversion process and deploys the SAP S/4HANA software.

Application-specific follow-up activities: Manual follow-up activities may also be required.
