Document Sequencing in Purchasing Documents

Dear All

We are using PSFSCM 9.2 PT 8.53 with no update/image. Though we are currently configured in a manner where the document series started with 1 and continues in the year. We're now wishing for changing the document series per year for the years to come for the purchasing documents. Kindly review example below. Our year begins on 1st July and ends 30th June next year:

Series Name Prefix	Document	Starting Number
YR_2019	Requisition	1
YR_2019	Purchase Order and so on	1
In the next year i.e. 2009 same way YR_2020	Separate series starting from1 for all of the documents	1

Currently its' configured in below way. Thus kindly suggest a way out if any. Also note due to audit requirement is it possible to restrict it in the way that when the year ends of 30-June-2018 i.e. it's 02-July-2019 now the documents are started for 01-July-2019 with the prefix say YR_2020 and 1 and than an entry/transaction needs to be recorder for previous year it's assigned with the proper prefix of YR_2019 and a proper in use number at that time.
