Number series work much like in the old modules, i.e. they create sequential serialnumber. For some objects you may only define a single number series, for other objects you may define a number series for each type, eg. for quotations you may define a number series for each quotation type.
Number series generate serialnumber of the form ANB, where A and B are static texts and N is a number that increases each time a new serialnumber is generated.
Depending on the object the number series may be applied at different times: for quotations the number series is applied when the quotation is saved and the quotation doesn’t have a quotation number. For invoices the number series is applied when the invoice is posted and it doesn’t have an invoice number.
