Sometimes while creating a new document (for E.g. Customer Order, Invoice, etc.) you may face with the issue "The Value OO-999" of the field Number is not unique.


The issue is connected to the fact that current prefix for the document was filled (due to the system architecture - 1 prefix may contain 999 documents).
For solving this issue you should change a prefix for the document ( in our example it is a Customer Order) ,  and system would start counting document numbers again.

Go to Administration > Service Settings > Document Prefixes:

You need to change Prefix for your document type (in our case it is a Customer Order):
Open Document prefixes link - system will show the window with Document Prefixes informational register.

You should find a Customer order in the list and change prefix to the  new one (for example  to CusO ).


After saving it - user should log out from the system and log in back (for the setting to be applied) and check new numeration.
