A Selective Data Transition (SDT) project is one of the three transition scenarios to SAP S/4HANA (alongside New Implementation and System Conversion). It involves transferring selected data and processes from an existing SAP or non-SAP system to SAP S/4HANA Cloud Private Edition while allowing for redesign and optimization. The question specifies that "most of the solution is being redesigned," so let's evaluate the options:
* A. Mix & Match: This is the correct answer. The Mix & Match approach in a Selective Data Transition combines elements of a new implementation with selective data migration. It allows for significant redesign of business processes while migrating only the necessary historical data (e.g., master data, open items) into the new SAP S/4HANA system. This approach fits when the goal is to rethink and optimize the solution rather than replicate the legacy system, aligning with the scenario described.
* B. Shell Conversion: This approach involves creating a "shell" copy of the existing system (without transactional data) and then selectively migrating data. It focuses on retaining the existing configuration and customizations with minimal redesign, which does not match the question's emphasis on "most of the solution being redesigned." Thus, it is incorrect.
* C. Dual-stack Split: This is not a standard term in SAP's Selective Data Transition methodology. It might loosely refer to splitting ABAP and Java stacks (e.g., in dual-stack BW systems), but this is unrelated to SDT for SAP S/4HANA Cloud Private Edition. It is incorrect here.
* D. Lift & Shift: This approach involves moving the existing system to SAP S/4HANA with minimal changes, typically as part of a system conversion or infrastructure migration. It does not involve redesigning the solution, making it unsuitable for this scenario.
In summary, theMix & Matchapproach is used in a Selective Data Transition project where most of the solution is being redesigned, offering flexibility to optimize processes and migrate selected data.
