VIM Taking other Business partner when invoice comes with same amount and reference num but

[Jagadeesh2]

Vendor sending same Invoice with same $ and Reference repeatedly,

Invoices are coming twice into VIM as system doesn’t flag it as duplicate because,

Main BP
171520868

It has Partners in the same BP
1716202376
1717293934

1st Invoice coming with same amount and Reference and processing for main BP 171520868,
Again, d same invoice is coming and processing with 1716202376, it’s not suspecting it as duplicate.

We do not have, /OTX/PF_BC_VNDR_IDENT or /OTX/PF_VNDR_RULES configurations in SAP VIM 16.3 BC, also don't have BC sets for this vendor thing to activate.

invoices come through Gmail into SAP from vendor.

How can we overcome this please help in detail.

Thanks In Advance.

Why it is happening is because of the following:-

SAP VIM checks for duplicates within the same BP by default.  Since your vendor has multiple BPs (e.g., 171520868, 1716202376, 1717293934), the system treats invoices under each BP as distinct, even if the reference and amount are identical.  You do not have the configurations /OTX/PF_BC_VNDR_IDENT or /OTX/PF_VNDR_RULES, which are used to group related BPs for duplicate detection

Below are some recommendations I can think of:-

Implement Vendor Identification Rules

• Activate and configure /OTX/PF_BC_VNDR_IDENT and /OTX/PF_VNDR_RULES to define vendor relationships.
• These allow VIM to treat multiple BPs as one logical vendor, enabling cross-BP duplicate checks.

 Use Custom Duplicate Check Logic

• If you cannot activate the above BC sets, consider implementing a custom duplicate check using:
• Reference number
• Invoice amount
• Vendor email domain or sender
• This logic can be embedded in the VIM DP Document Processing rules or via a custom enhancement.

 Centralize Vendor Master Data

• Review your vendor master setup to see if multiple BPs can be merged or linked via central BP roles.
• This simplifies duplicate detection and improves data governance.

 Pre-Processing Validation

• If invoices are coming via email (Gmail), consider adding a pre-validation step before ingestion into VIM:
• Use a middleware or email parser to check for duplicates across BPs.
• Flag or block duplicates before they reach VIM.
