SAP Simplification Item Check Basics Before an SAP S/4HANA Conversion

The Simplification Item Check is a technical preparation activity for an SAP S/4HANA conversion. It evaluates the source system against simplification items relevant to the planned target release and identifies objects, processes, or settings that need analysis before the conversion window.

A useful way to position the check is as a scope and risk filter. It provides conversion-specific findings, while the project still needs separate work for custom code, add-ons, interfaces, data volume, business processes, security, and technical operations.

01Understand the simplification item catalog

The simplification item catalog describes functional and technical changes introduced by SAP S/4HANA. An item can describe a changed data model, a replaced transaction, a changed business process, a removed function, or a required preparation step.

Each item should be read in the context of the planned target release and the processes used by the organization. A catalog entry that appears broadly relevant may require no action when the associated functionality is not used, while an item affecting a heavily used process can require detailed remediation.

The catalog is therefore a decision aid, not a generic checklist. Record the relevant item, affected application area, required action, responsible owner, evidence, and status in the project worklist.

02Run the check against the planned target

Run the Simplification Item Check after the target release, conversion approach, and system scope have been established. The source system should represent the configuration and usage that the project intends to convert. Complete the run early enough to leave time for analysis, remediation, testing, and a repeat check.

Use the project’s supported SAP tooling and the preparation procedure for the selected target release. Confirm that the required software components, authorizations, and connectivity are available before starting. Keep the run output with the project baseline so that later runs can be compared.

The target release matters because the applicable simplification items and their required actions are release-specific. A result from an earlier planning baseline should be reviewed again when the target release or scope changes.

03Classify findings before assigning work

Read each finding and classify it using evidence from the source system. A practical classification separates findings into:

• Relevant and actionable: the affected functionality is used and the item defines a required preparation or remediation step.
• Relevant with analysis required: usage or impact is unclear and needs confirmation from a functional or technical owner.
• Not relevant by evidence: the system does not use the affected functionality, with the reason documented.
• Already remediated: the required action is complete and supported by a transport, configuration record, test result, or other evidence.

Avoid closing a finding only because its text looks familiar. Confirm the affected organizational units, documents, custom developments, interfaces, roles, and operational procedures where applicable. Attach the evidence that supports the decision.

04Assign remediation across the project

Simplification findings often cross team boundaries. A functional owner may confirm process usage, an ABAP owner may assess custom code, an integration owner may review interfaces, and a technical owner may coordinate system preparation. Assign one accountable owner to each actionable finding and define a due date.

Track dependencies explicitly. For example, a data-model change may affect custom reports, interfaces, authorizations, and test cases at the same time. Link the finding to the relevant design decision, remediation item, transport, and test evidence so that the project can follow its full lifecycle.

The SAP S/4HANA migration overview provides the broader relationship between preparation, technical conversion, testing, and cutover planning. Use it when positioning the check within the overall migration workstream.

05Use SUM planning with the check results

The Simplification Item Check supports the conversion plan but does not replace the technical conversion procedure. Findings that affect system preparation, downtime, software update activities, or follow-on validation should be coordinated with the selected SUM plan.

Keep the check results, remediation status, and conversion prerequisites synchronized. The SAP SUM overview for SAP S/4HANA migration explains how SUM fits into the technical conversion sequence and helps the team separate preparation activities from execution steps.

A finding can be technically resolved while still requiring business validation. Conversely, a business decision can identify additional remediation even when the technical check no longer reports an error. Treat both forms of evidence as part of the release readiness record.

06Repeat the check after remediation

Run the check again after completing significant remediation and after changes to the target release or system scope. Compare the new output with the previous baseline and preserve the history of status changes.

The repeat run should confirm that actionable findings are resolved, explain findings that remain open, and identify new impacts created by configuration or development changes. Schedule the final run before the conversion rehearsal so that unresolved items are visible in the rehearsal plan.

A successful repeat check is one input to readiness. The project should also complete custom-code analysis, guided by the practices in the SAP module glossary, add-on and interface assessment, security review, data and process validation, technical rehearsal, and business-process testing.

07Connect related conversion dependencies

Some simplification items affect master data or cross-application integration rather than a single transaction. Business Partner preparation is a common example: the project must coordinate the conversion of customer and vendor master data with the processes and interfaces that consume it.

The Business Partner conversion in SAP S/4HANA migration article covers that dependency in more detail. Use the finding worklist to connect such activities to data owners, integration owners, test scenarios, and cutover tasks.

Testing should prove both the technical correction and the business outcome. The SAP S/4HANA migration test strategy article describes how to organize testing evidence around converted processes, integrations, authorizations, and regression risk.

08Operational checklist for the SIC run

Use this sequence to keep the activity controlled:

1. Confirm the source system, target release, conversion approach, and system scope.
2. Establish the project baseline and identify the owners for functional, development, integration, security, and technical findings.
3. Run the Simplification Item Check using the supported preparation procedure for the target release.
4. Export or record the findings with their identifiers, descriptions, status, owner, and evidence.
5. Validate relevance with the teams that own the affected processes and objects.
6. Remediate actionable findings and record transports, configuration changes, code changes, and test results.
7. Review dependencies with the conversion plan, data activities, interfaces, and cutover sequence.
8. Repeat the check after remediation and before the conversion rehearsal.
9. Obtain explicit acceptance for remaining findings, including the reason, owner, mitigation, and decision authority.

This workflow turns the check from a one-time report into a controlled readiness process. The project can then show why each finding is open, resolved, excluded by evidence, or accepted with mitigation.
