Hi Nabil
You can setup the check for duplicate invoice in vendor also LFB1-REPRF, in company code view--Payment Transactions.
Here is the F1 help on the field
Check Flag for Double Invoices or Credit Memos
Indicator which means that incoming invoices and credit memos are checked for double entries at the time of entry.
Use
Checking Logistics documents
Firstly, the system checks whether the invoice documents have already been entered in the Logistics invoice verification; the system checks invoices that are incorrect, or invoices that were entered for invoice verification in the background.
Checking FI documents
The system then checks whether there are FI or Accounting documents that were created with the original invoice verification or the Logistics verification, and where the relevant criteria are the same.
Checking Logistics documents
In checking for duplicate invoices, the system compares the following characteristics by default: Vendor Currency Company code Gross amount of the invoice Reference document number Invoice document date
If all of these characteristics are the same, the system issues a message that you can customize.
When you enter credit memos or subsequent adjustments, the system does not check for duplicate invoices.
Exception: Country-specific solution for Argentina, where invoices and credit memos are checked for duplicate documents.
No message is issued if you enter a document that has previously been reversed.
Dependencies
The system only checks for duplicate invoices in Materials Management if you enter the reference document number upon entering the invoice.
In Customizing for the Logistics invoice verification, you can specify that the following characteristics should not be checked: Reference document number Invoice document date Company code
This means that you can increase the likelihood that the system will find a duplicate invoice, because you can reduce the number of characteristics checked.
Example
The following document has already been entered and posted:
Reference document number: 333
Invoice date: 04/28/00
Gross invoice amount: 100.00
Currency: EUR
Vendor: Spencer
Company code: Munich
You have made the following settings in Customizing:
The field "Reference document number" and "Company code" are deselected, which means that these characteristics will not be checked.
Now you enter the following document:
Reference document number: 334
Invoice date: 04/28/00
Gross invoice amount: 100.00
Currency: EUR
Vendor: Spencer
Company code: Berlin
Result
Because you entered a reference document when you entered the invoice, the system checks for duplicate invoices.
The reference document number and the company code are different from the invoice entered earlier, but these characteristics are not checked due to the settings you have made in Customizing.
All other characteristics are the same. As a result, the system issues a message that a duplicate entry has been made.
If the "Reference document number" had been selected in Customizing, the system would have checked the document and discovered that it was different from the invoice entered earlier, so it would not have issued a message.
Checking FI documents
Depending on the entry in the field "Reference", one of the following checks is carried out: 1. If a reference number was specified in the sequential invoice/credit memo, the system checks whether an invoice/credit memo has been posted where all the following attributes agree: Company code Vendor Currency Document date Reference number 2. If no reference number was specified in the sequential invoice/credit memo, the system checks whether an invoice/credit memo has been posted where all the following attributes agree:Company code Vendor Currency Document date Amount in document currency
Hope this is what you were looking for.
