When posting outgoing or incoming payments, after i choose bank account, there's the option to also select the GL account. Kindly find attached the screenshot. How do i configure the system to automatically choose outgoing payment GL when its an outgoing payment and incoming payment GL when its an incoming payment. I dont want to have to manually input this when creating payment.

Please note that i have created the reconciliation GL and have maintained the two subaccounts. I have also connected the reconciliation GL to the bank account.

Hi seunabati,
As you explain when posting outgoing or incoming payments, after i choose bank account even though you’ve already set up the reconciliation account and linked it to the bank account. Please follow the step by step configuration as i show you below.

1. Bank Account Master Data (Manage Bank Accounts App)
In the bank account master record, you can assign:Main Bank Reconciliation Account (already done in your case). Payment Subaccounts for Incoming and Outgoing flows. These subaccounts are what the system uses to automatically post to the correct GL when you create payments.

2. Assign Payment Methods
Go to Manage Payment Methods for Company Code.
For each payment method (e.g., wire transfer, check, SEPA), assign: The Bank Account. The GL Subaccount (Incoming or Outgoing). This ensures that when you select a payment method, the system knows which GL account to hit.

3. Automatic Account Determination
In SSCUI (Self-Service Configuration UI) for Bank Accounting, check: Define House Banks and Account IDs → link the bank account ID to the reconciliation account and subaccounts. Define Posting Rules → specify which GL account is used for debit (outgoing) and credit (incoming).

4. Payment Transactions
When you post an outgoing payment, the system looks at: The payment method + bank account ID → derives the outgoing subaccount. When you post an incoming payment, the same logic applies but points to the incoming subaccount.

Hope you will get the issue resolved.
