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.(also all other options also has no value maintained)
Environment
SAP Business ByDesign
Reproducing the Issue
- Go to Supplier Invoicing work center
- Select Invoices and Credit Memos view
- Select the respective invoice and copy
- A new invoice is created
- Error: Invoice may be a possible duplicate
Cause
Default criteria : Same Supplier, External ID matched 80% or above and Invoice date + or - 7 days.
Additional criteria :what you set in BC activity "Supplier invoice exception "
Firstly system will check and need all Default criteria to match between both invoices to raise exception.
When all or one of the elements in default criteria does not match then only system will check for additional criteria other wise it will not check for them.
System will check and need all additional criteria to match between both invoices to raise exception
and also system will check for one more criteria that is PO reference matched or not only when additional criteria is used by system.
Resolution
System will always check for default criteria first and if all matches then exception is raised accordingly.
if not it will check for additional criteria and if all matches then exception is raised accordingly.
Note:
System will throw duplicate "warning" if the previous invoice is not posted/paid invoice cause you can void the previous invoice.
System will throw duplicate "error" if the previous invoice is posted/paid invoice.
