In this step, you define the account assignment references for your transactions. The account assignment reference controls which G/L account in Financial Accounting is used to manage the respective position.
You can either manually assign the account assignment reference to the transaction or define an automatic determination which will give you a default value. The account assignment reference name is user-defined. In the definition, you assign a G/L account and a cost center, if necessary. In this way, both the link to FI and Controlling are assured.

If a posting category has been defined in account determination which posts to a balance sheet account, e.g. 13 balance sheet to bank, the balance sheet account is taken directly from the account assignment reference definition. The principle increase when you create a fixed-term deposit is posted as follows:
40 Account from account assignment reference 50 Bank account from payment details
If a posting category has been defined, which triggers a payment activity, e.g. 12 balance sheet to sub-ledger, the flow is posted as follows:
40 Account from account assignment reference 11 Customer In the background, the system replaces the account from the account assignment reference with a G/L reconciliation account.
