3708634 - System picks incorrect default G/L Account during Journal Entry postings via TBB1 - SAP S/4HANA Cloud Public Edition

• During Journal Entry postings via transaction TBB1, the system selects the SAP-delivered default Payment Request Clearing Account (315) instead of the intended Treasury Clearing Account (XXXXXXXX).
• The configured account (XXXXXXXX) in the Account Determination substitution settings is not being picked up by the system. 

SAP S/4HANA Cloud Public Edition

The behavior of the system is aligned with standard SAP functionality, depending on whether the transaction's cash flow involves a payment request.

• When a payment request is required, the system automatically posts to the SAP-delivered default Payment Request Clearing Account (G/L 315), as defined by SSCUI 105589 - Define Clearing Accounts for Cross-Country/Region Bank Account Transfers.
• If no payment request is involved, the system uses the configured Treasury Clearing Account (XXXXXXXX). This account is linked to account symbol X and is utilized for direct posting to the Bank Clearing Account.
• The selection of G/L accounts is determined by the transaction type and the necessity of the payment request, making it the system's standard behavior.
