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.

Hi,
You need to ensure two main things:

1. G/L Account Type: Your two subaccounts(Incoming /Outgoing) must be created with the G/L Account Type 'C' (Cash Account).

2. G/L Account Subtype: This is the most importent part.

   • Your reconciliation account should have the Subtype 'B' (Bank reconciliation Acc).

   • Your Incoming / Outgoing payment G/L subaccounts must both have the Subtype 'S' (Bank Subaccount).

Then in the Manage Bank Accounts app:

• Go to your relevant House Bank Account.

• Under the G/L Accounts tab, you link all three G/L accounts. when you link the G/L Subaccounts S type, the system knows which one is for an Incoming and which for Outgoing payment based on internal logic.

When you post a payment (either outgoing or incoming) and select that Bank Account, the system uses the transaction type to autamaticaly pull the correct S type GL account. If the field is still open for manual entry, it means the Subaccount link in Manage Bank Accounts is either missing or the Subtype is incorrect. You should not have to manually input it.

Thanks
Regards
