Which of the following must be entered during the asset posting for external acquisition? (Select two correct answers)

In the context of asset posting for external acquisition, the transaction type holds significant importance as it defines the nature of the transaction being executed. When dealing with asset postings in SAP, the transaction type determines how the system processes the entry. This includes identifying whether it is an asset acquisition, transfer, or retirement. It ensures that the correct accounting treatment is applied and that the financial statements reflect the appropriate transactions.

Regarding the other choices, while the purchase order number, vendor number, and posting key may play roles in various transaction types, they are not strictly necessary for every asset posting scenario. The purchase order number pertains to procurement and is relevant when an asset is being acquired via a purchase order. Similarly, the vendor number is crucial when dealing with vendor-related transactions, especially in procurement processes, but it is not a definitive requirement for all asset postings. The posting key is important for indicating the debit or credit nature of the transaction but does not specifically need to be entered in every asset acquisition case.

In summary, for asset postings specifically related to external acquisitions, the transaction type is essential as it dictates the type of transaction and how it is handled in the system.
