Duplicate Voucher (Vendor Invoice) not detected on entry

(0) ShareShare
ReportReport
Posted on by 180

Migrated client from SL 7.0FP1 to SL 2015 CU1 and when entering invoices (03.010.00) the invoice number "checking for duplicates" is not looking back more then six months based on user reports.  I have not dug into the back-end yet but wanted to post and ask if anyone had a quick answer?

Thanks!

    Yes - go to AP Setup, Other Options tab:

    Periods to Check for Duplicates:

    Maximum number of periods that the software checks for duplicate invoice records. The value here is used only if Warn on Duplicate Invoices is selected. If so, the number of periods in this field determines the extent of the search for duplicates. The setting in this field can be changed at any time.

    While this option is very useful for preventing double-entry of invoices, there are trade-offs. The check for duplicates happens twice during the entry for each invoice – when the invoice number is entered and when the invoice amount is entered. The more periods set for the search, the longer it will take. Also, if you have numerous invoices from a supplier for standard purchases which have the same dollar amount, you will constantly be warned of this condition.
