The current vendor payment process in Dynamics 365 Finance & Operations (D365 F&O) is constrained by a rigid, one-to-one relationship between the "Method of Payment" and the company's "Bank Account." This design forces organizations to create and maintain a separate, often redundant, method of payment for each bank account, even when the payment type (e.g., SEPA Credit Transfer) remains the same. This leads to administrative overhead, a complex master data landscape, and a lack of flexibility.

This proposal outlines a new, modernized approach that decouples the bank account selection from the initial payment proposal, introducing a dynamic, intelligent selection process at the point of payment file generation.

The Problem: In the standard D365 F&O workflow, the Payment proposal function requires a predefined Method of payment as a filtering criterion. This method of payment is, in turn, configured to post payments to a specific  Bank account. This creates an unnecessary and inefficient dependency: 

• Master Data Proliferation: To facilitate payments from multiple bank accounts, a separate Method of payment must be created for each bank account. For a company with 10 bank accounts that all use SEPA, this means setting up 10 separate SEPA methods of payment. 

• Operational Inefficiency: Users are forced to run multiple payment proposals or create separate journals for each bank, even for a single payment run. This manual process increases the risk of human error and slows down cash management. 

• Lack of Centralization: The system lacks a centralized point of control for selecting the best bank account for a given payment run, preventing sophisticated cash management and optimization based on real-time data.

The Proposed Solution: Introduce a new, configurable workflow that enables a single payment journal to manage payments across multiple bank accounts. The key change is the ability to select the specific bank account at the final stage of the process—when the payment file is generated. 

Proposed Workflow:

1. Generic Payment Proposal: The user runs the payment proposal using a single, generic Method of payment (e.g., "SEPA Credit Transfer") that is not linked to any specific bank account. Instead, this generic method would be configured, the bridging account will be defined at the bank acounts (standard feature)
2. Unified Payment Journal: The system creates a single Vendor payment journal containing all the approved payments. The journal lines will use the placeholder ledger account as the offset account. 
3. Dynamic Bank Account Selection: When the user clicks the Generate payments button , a new dialog box appears, presenting a list of all bank accounts that are valid for the payment type and currency. From this list, the user selects the specific bank account to be used for the payment file generation. 
4. Intelligent Bank Account Prioritization (Advanced Feature): This dialog box would optionally include a new feature: an intelligent prioritization engine. This engine would automatically suggest or select the optimal bank account based on user-defined, configurable criteria. The primary criterion could be the bank account with the highest available balance, leveraging existing system data on cash position and cash flow forecasts from tools like  Finance Insights. 
5. Automated Journal Update: After the bank account is selected, the system automatically updates the journal lines, replacing the placeholder ledger account with the selected bank account. The system then generates the payment file and posts the journal in one seamless action.

Business Benefits:

• Reduced Administrative Burden: Eliminates the need to maintain redundant Methods of payment for each bank account, simplifying master data management. 

• Enhanced Operational Efficiency: Consolidates multiple payment runs into a single, unified journal, saving time and reducing the risk of errors.

• Improved Financial Control: Centralizes the bank account selection process, allowing finance teams to maintain tighter control over disbursements.

• Strategic Cash Management: The advanced prioritization feature provides a powerful tool for optimizing cash flows by automatically selecting accounts with sufficient liquidity to avoid overdrafts and manage working capital more effectively. 

• Future-Ready: This feature lays the groundwork for further automation in cash management, linking transactional processes directly with financial insights and analytics.

Conclusion: This proposal addresses a critical inefficiency in the D365 F&O payment process. By decoupling the bank account from the initial proposal and introducing a dynamic selection and prioritization feature, Microsoft can transform the vendor payment module from a rigid, manual process into a flexible, intelligent, and strategically valuable tool for modern finance teams. This is a logical and necessary step in the evolution of D365 Finance & Operations.
