Overview:

In the current setup under Accounts Payable > Parameters > Invoice link > Invoice the “Reject duplicate invoice” parameter is designed to prevent reuse of the same invoice number. However, the behavior appears to be limited in scope and could benefit from more granular control.

Suggested Enhancement:

Introduce two distinct toggle options under the “Invoice number used” field in Accounts Payable parameters form to provide better control over duplicate invoice validation as detailed below :

1. Reject Duplicates for Same Vendor toggle

• Functionality: Prevents reuse of the same invoice number for a single vendor.
• Example: If invoice number "Inv1" is used for vendor ABC, the system should block reuse of "Inv1" for ABC again. The same invoice number "Inv1" can be used for vendor XYZ.

2. Reject Duplicates Across Legal Entity toggle

• Functionality: Prevents reuse of the same invoice number across all vendors within the legal entity.
• Example: If invoice number "Inv1" is used for vendor ABC, the system should block reuse of "Inv1" for any other vendor, such as XYZ, within the same legal entity.

Benefits:

• Enhances data integrity and audit compliance.
• Addresses customer concerns regarding invoice duplication across vendors.
• Provides flexibility to align with varying business policies.
