This blog is for Upgrade of S/4HANA – t3 of the Prepare Phase mandatory steps to be done in sequence below. Simplification Item Catalog is a tool that allows you to search or browse the complete collection of simplification items online. Each simplification item details the steps that need to be taken for the conversion and/or the upgrade from a business and a technical point of view, both preparatory and follow-on steps and each item is available as a SAP Note. This is a mandatory step and will be triggered by SUM tool. We will focus on Sandbox type system with co-deployed (embedded) gateway.
Readiness Check (RC) is relevant to Conversion to S/4HANA and will be discussed in Conversion blogs.

(2) Status column is Released
(3) Last Consistency Result shows if there are data inconsistencies when system is migrated to new data structures that could cause conversion to fail, so you are aware to correct or exempt them before actual conversion starts. Red is for Inconsistency at level Error – these are mandatory to be fixed before upgrade/conversion. Yellow is for Warning and Green is for No inconsistency, the ones with X are Not applicable.
(4) Exemption shows items that have errors can be exempted.
Notes column shows the Note Number to refer to for the item that you can click and directly go to for information.
The first line points to SAP Note 2618018 – S4TWL – Generic Check for SAP S/4HANA Conversion and Upgrade
The next step is to see individual Simplification Item detail log.
(5) Display Consistency Log to show the error in more detail
Note the above error is in SI22 – GENERIC_CHECKS. The solution is provided to run report RS4SIC_TNIW5CORR and points to note 1484142 – MRN1: Incorrect Customizing entries deleted for more information. Please run the report in SA38 – Client 000.
(6) Display Exemption Log to show the exemptions applied. (a) Messages with return code 7 will block system conversion, so action is required. You may be able to set exemption for the error and get through. (b) Messages with return codes 8 or 12 will block system conversion and need detailed application specific knowledge to resolve and you may have to refer to the note/open OSS message to get them resolved.
Normally for Conversion it is expected that there are 20+ items above and each one takes its own time to resolve.
