SAP S/4HANA Transition – The Right Mix with Natuvion's ALLFIELD Approach

Selective Data Transition to SAP S/4HANA with Natuvion's ALLFIELD approach.

(4 min read)

Neither Greenfield nor Brownfield offer you what you expect from the SAP S/4HANA transition? In this case, you can benefit from the Selective Data Transition with Natuvion’s ALLFIELD approach, a smart way to move to the new ERP system. The ALLFIELD approach aims to maintain a sensible balance between retaining and redesigning existing processes, data and structures. But how does the ALLFIELD approach work?


2 Steps to SAP S/4HANA with Natuvion’s ALLFIELD approach

Step 1: The System Shell Moves and Gets Adapted

With the ALLFIELD approach, an empty system shell is first created, which only contains the customizing and the relevant customer-specific programming from the productive SAP system. This step is also called “Shell Creation”. Without the corresponding master and transaction data, this shell can be easily migrated to SAP S/4HANA.
In its empty form, you can now also adjust the customizing of processes and organizational structures that would otherwise be prevented by the master and transaction data. The shell also serves as a template for project-specific test systems.


Step 2: Only Selected Data Follows into the New SAP S/4HANA System

In the next step, the data is selectively transferred from the old system to the adapted system running on SAP S/4HANA and its new data structures. As a customer, you therefore have the freedom to decide to what extent you want to transfer your existing data. This can be done step by step and data from several SAP ERP systems can be combined in one SAP S/4HANA system.
If desired, you can cleanse and harmonize the data in the same step. With the ALLFIELD approach, the time in which the systems are not available due to the transition can be reduced to a minimum, up to a near-zero downtime.

Move to SAP S/4HANA with the SAP ACTIVATE Methodology

One thing is certain: A successful SAP S/4HANA transition can only succeed with a holistic and comprehensive approach. It is important to combine flexibility in implementation with security in planning, especially in the calculation of effort and costs.
In addition, it must be ensured that effects and downtimes during go-live are reduced to a minimum. SAP has developed the ACTIVATE methodology for this purpose. The SAP S/4HANA transition consists of four phases: Prepare, Explore, Realize and Deploy.
