2905003 - You get "Possible Duplicate" error when you create a New Invoice with the Same Data from an Old Supplier Invoice

Symptom

You have created a supplier invoice by copying or manually entering same data from a previous invoice and get the error: "Invoice may be a possible duplicate".

You have also set the field (External Document ID - Similarity(%)) to zero in the fine-tuning activity:Supplier Invoice Exceptions, to avoid the system from checking duplicate for external document id.

It says:'If you enter zero, the system does not check for the external document ID'.

Environment

SAP Business ByDesign

Reproducing the Issue

  1. Go to Supplier Invoicing work center
  2. Select Invoices and Credit Memos view
  3. Select the respective invoice and copy
  4. A new invoice is created 
  5. Error: Invoice may be a possible duplicate

Cause


In this case, you get error even though you have set this field "External Document ID - Similarity(%)" as 0.

This field works on Fuzzy logic(fuzzy matching program). The value of fuzzy parameter determines the percentage matching (default value is 8000) and only if it matches 80% then error is raised.

Here, the match is equal to or greater than 80%, so the duplicate exception is raised.

Resolution

Please check and maintain the filters in the "Configuration: Supplier Invoice Exceptions"  as per your requirement, so that exception is raised accordingly.

Note:

System generally raises "warning" when you copy from a not posted invoice since it is assumed that you can change the external document ID, Supplier Information in the invoice and hence, allow you to post invoice.

System will throw duplicate "error" if you copy from a posted invoice.
