Duplicate check searches for existing suppliers in your site's vendor database by a combination of:
- Exact match to Dun & Bradstreet ID (D-U-N-S Number)
- Strict match to the full supplier name
- At least a partial match to supplier name followed by a partial or full address match (partial name match must occur before address matching is attempted)
- If your site uses custom duplicate check, partial matches to answers
The duplicate check scores matches based on predefined logic.
- Matching is case insensitive
- Score is expressed as a percentage between 0 and 100
- Scores ≥ 70% are labeled STRONG
- Scores < 70% are labeled WEAK
- Exact matches (score of 100%) displayed first, then partial matches displayed in descending order
In addition to SAP Ariba's default duplicate check on name, street address, city, state, country, postal code, and D-U-N-S Number, your company can specify additional questions in the internal supplier request for use in the duplicate check.
For custom duplicate check, the answer must match starting with the first character. If the answer contains any spaces, each space-separated word or group of characters is matched separately, and each must either fully or partially match starting with the first character. For example, if your site has an existing supplier with the value "Green Energy Corporation" in a field used for a custom duplicate check, "Green," Energy," and "Corporation" are all indexed for matching separately. Any corresponding supplier request answer that starts with "G," "E," or "C" is considered for matching, and answers such as "Gre," "Energ," and "Corp" are matched. Answers such as "Greed," "Reen," and "Gre Energion" are not matched.
Matching is case insensitive. The duplicate check scores these different matches based on predefined logic. The score is expressed as a percentage between 0 and 100, with scores of 70% and above considered strong matches and scores of less than 70% considered weak matches.
When the requester submits the supplier request (for internal requests only) and during supplier request approval (for both internal and external supplier requests), the duplicate check displays the top 20 matching suppliers, based on match score, in the following order:
- Exact matches (score of 100%) first.
- Partial matches next, in descending order based on score.
