S4HANA conversion DTV tool (data transition validation)

Tool for Validating Data Transition

Throughout the S4HANA conversion process, the migration of FICO data and other essential data elements to new data structures takes place. It becomes crucial for businesses to verify the accuracy of this conversion and provide evidence of its correctness. In this context, the utilization of the Data Transition Validation (DTV) tool is recommended to fulfill this verification objective.

Installing the DTV Tool: Step-by-Step

To set up the Data Transition Validation (DTV) tool, follow these instructions:

1. Access the Master Note: Begin by referring to the central note 3117879 – "DTV Tool – Central Note." This serves as the comprehensive guide for the DTV tool installation process.
2. Target System Compatibility: It's important to note that the DTV tool is compatible with S4HANA 2021 and later versions as the target system. For these versions, no separate installation is required; the tool is readily available.
3. Source System Requirements: For the source system, ensure that you are on the appropriate support package level. Alternatively, you can opt for installation via the TCI (Transport-Based Correction Instructions) delivery note 3103342 – "DTV Tool Initial Delivery."

By following these steps, you can effectively set up and utilize the DTV tool to validate data transitions during the S4HANA conversion process.

Scenario:

Imagine you're embarking on a system conversion and have the task of scrutinizing your business data both before and after the transition. The objective is to ensure data integrity without delving into exhaustive manual validation for every single document. Your aim is to streamline the validation process while maintaining efficiency and cost-effectiveness. Additionally, you wish to attain a preliminary overview of the data's accuracy during a test run.

Introducing Data Transition Validation:

Data Transition Validation emerges as a novel solution tailored to your needs. This tool empowers you to establish a project framework and execute validation reports, supplied by SAP, to assess your data's quality.

Availability and Implementation:

Designed for conversions targeting SAP S/4HANA 2022 and higher, Data Transition Validation is seamlessly integrated into the target system through SAP BASIS software delivery. On the source system, accessibility is facilitated via TCI SAP Notes (TCI: transport-based correction instruction). This tool is open for utilization by both customers and partners. While involving SAP experts is advantageous, it's not mandatory.

Pre-Packaged Validation Reports:

Data Transition Validation comes equipped with a set of predefined SAP reports for data validation. Over time, this suite of reports may expand. The choice of reports for validation is a component of the project definition.

Detailed Check Reports:

A comprehensive list of the available check reports can be found in SAP Note 3117879 – "DTV Tool – Central Note."

Process Overview:

The process involves extracting pertinent data twice: once shortly before initiating downtime, and once post-conversion on the target release. Subsequently, Data Transition Validation is employed to compare the extracted data, presenting you with a concise outcome within the tool's interface.
