The Duplicate numbers module regularly checks the system for duplicate part numbers, serial numbers, and invoice and credit memo numbers. A red warning will then appear in the System Health overview of the xentral interface if the system has detected duplicate numbers.
Searches items for duplicate item numbers
Searches invoices and credit notes for duplicate document numbers
Searches addresses for duplicate customer and vendor numbers (customer and vendor numbers)
Under Administration > Settings > System > Basic settings > Number ranges you can find the option to activate the warning about duplicate numbers. Directly below it there is also an option to be warned about duplicate serial numbers. Enabling this is useful when items with serial numbers are kept in inventory or sold.
Verification of duplicate numbers is performed by the Verify duplicate numbers process starter. It must be enabled and run regularly for the module to be functional. If duplicate numbers are found, a corresponding error message is displayed in the System Health overview of xentral.
If you are alerted about duplicate numbers, it is possible to jump directly to the module via the System Health overview or via App Center > Duplicate numbers. In the module there is an overview of all duplicate numbers found.
In the example below, the module has detected two items with the same item number and lists them.
During the creation of items, an alert is issued if an item number has been assigned twice.
Duplicate item numbers may be assigned if there is an overlap between the global number range from the company data (Administration > Settings > System > Basic settings > Number range), the project-specific item number range and the number ranges in the item categories.
In the item itself, item numbers can be changed manually. If you do not want to use your own numbers within an item category, but instead use the global number range, you can set the Use central number range option for each category. This is possible under Administration > Settings > Master data > Item categories and then clicking on the desired category.
Duplicate document numbers for invoices and credit notes should not occur as a rule. However, this can happen if, for example, the set global or project-specific number range has been reset/changed, or if documents have been loaded into the system via the document importer.
It is not possible to fix duplicate voucher numbers via the xentral interface. The voucher numbers have to be retyped directly in the database tables credit note and invoice at the value belegnr.
Duplicate serial numbers can occur if an already existing serial number was stored again or if a serial number is linked several times to one or more delivery bills
