Comprehensive Detailed Explanation with all SAP S/4HANA Cloud References In SAP S/4HANA, the legacy data transfer process in Asset Accounting is used to migrate asset-related data from legacy systems into SAP. Transaction AS91 specifically supports the posting of takeover values for assets during the legacy data transfer process. Let's analyze each option to determine the correct answer. Explanation of Each Option: D. Posting of take over values * Correct : Transaction AS91 is designed to post the takeover values of assets during the legacy data transfer. These takeover values represent the initial acquisition and production costs (APC), accumulated depreciation, and other financial information for assets as of a specific key date (e.g., the go-live date). This ensures that the asset balances from the legacy system are accurately transferred to SAP. * Reference : According to SAP documentation, AS91 is used to post takeover values for assets during the legacy data transfer process, ensuring continuity in financial reporting. A. Setting the company code status for legacy data transfer * Incorrect : Setting the company code status for legacy data transfer is typically done using transaction OAYR or similar configuration steps, not via AS91. AS91 focuses on posting takeover values, not configuring the company code status. * Reference : The company code status for legacy data transfer is part of the preparation phase and is managed separately from the actual posting of takeover values. B. Creation of master data * Incorrect : While asset master data must be created before posting takeover values, this is typically done using transactions like AS01 or through batch uploads. AS91 does not create asset master data; it only posts the financial values for existing assets. * Reference : Master data creation is a prerequisite for AS91 but is not performed within the transaction itself. C. Posting the summary write off in G/L * Incorrect : Posting a summary write-off in the General Ledger (G/L) is unrelated to the legacy data transfer process in Asset Accounting. AS91 focuses on transferring asset-specific financial data, not writing off balances in the G/L. * Reference : Summary write-offs are typically handled in Financial Accounting (FI) or Controlling (CO) processes, not during asset legacy data transfer.
