Project Overview
Company X was implementing the SAP S/4HANA system (on-premise, version 2022), but did not have the SAP MDG module or the licenses to activate it. As a result, a key mechanism for master data approval (workflow) was missing — posing a significant risk during the data migration process.
Additionally:
The SAP Migration Cockpit (LTMC) does not offer a standard approval mechanism for data before migration.
The organization operates in an environment where data quality is critical, and every change must be auditable.
Lack of control could have led to the introduction of incorrect or inconsistent data into the system.
Challenge
The goal was to create an alternative Change Request (CR) mechanism that:
Does not require SAP MDG or additional licenses.
Blocks data migration until the CR is approved.
Enables full auditability of the process.
Enhances data security and process compliance.
Identified risks associated with the lack of such a mechanism included:
No workflow or data control in the standard LTMC process.
Potential migration of incorrect data.
Non-compliance with audit requirements.
Solution
A custom solution was developed to implement workflow logic that:
- Generates a unique CR number for each data package.
- Requires CR approval within a dedicated transaction.
- Blocks data migration until the CR is approved.
- Logs all user actions for full audit traceability.
Implementation process
| Area | Description of Changes |
|---|---|
| SAP Migration Cockpit | Migration blocked if CR is not approved |
| ABAP Program | Tool for generating and managing CRs |
| Data Validation | Checks for approved CRs before migration |
| User Control | Restricted access without CR |
| Audit & Reporting | Tracks approval history and user actions |
Generating a Change Request (CR)
Each data package must receive a unique CR number before migration.
The CR is linked to a specific migration and stored in a control table.
Blocking Migration Until Approval
If the CR is not approved, data cannot be uploaded to SAP.
The system verifies the CR approval status before starting migration.
Verification in Migration Cockpit Staging Tables
A new field “CR Status” was added at the staging table level.
The field is checked automatically before migration.
Audit and Monitoring
All user actions are logged and available for audit.
Reporting allows tracking who approved the data and when.
Team and timeline
| Role | Team Size | Duration |
| ABAP Developer | 1–2 | 3 weeks |
| SAP MD Consultant | 1–2 | 2 weeks |
| Tester (UAT) | 1–2 | 1 week |
| Project Manager | 1 | Entire project |
Total duration: approximately 6 weeks
