How to setup the naming series?

[Yamen_Zakhour]

Then maybe you can give draft documents a temporary name like temp-inv-0001 then create a server script on submit to Rename Doc

In that case,

1. There is no need for our additional fields
2. Set the default naming series to “Temp-INV-####”
3. Create a server script on submit that will;
   3.a. Get last doc from invoiceIndex
   3.b. Get the last_doc.index
   3.c. Check customer territory if it’s export or not
   3.d. Rename the current doc to “INV-last_doc.index” or “INV-EX-last_doc.index”
   3.e. Delete all docs in invoiceIndex
   3.f. Create a new doc in invoiceIndex with the index of last_doc.index + 1
