The account determination for planned delivery costs based on the condition type is controlled by the account key that is assigned to the condition type in Customizing for Materials Management under Purchasing -> Conditions -> Define Price Determination Process -> Define Condition Types. The account key determines which general ledger accounts are posted to during invoice verification. References: SAP S/4HANA Sourcing and Procurement | SAP Learning, Course S4515, Unit 3, Lesson 1.
