Transaction AS91 (Create Old Asset) is used during legacy data migration in Asset Accounting to enter and post historical acquisition and accumulated depreciation amounts—so-called “take-over values.” When the legacy transfer date is reached, these values are automatically posted to the G/L, bringing the asset balances in SAP in line with the previous system. AS91 is not used to set company-code transfer status, to post summary write-offs, or to create normal (new) asset master data records; it is reserved for importing legacy balances.

A. Company-code transfer status is set in Customizing (transaction OAYC), not with AS91.

B. Summary write-offs are recorded with specific FI postings, not via AS91.

C. Standard asset master data is created with AS01; AS91 is intended for legacy balance entry, not ordinary master-data creation.
