Sorry, I forgot to reply to you. I will update the blog with examples later on.

Per.1 to Per.1 is for your regular postings e.g. you Have period 12-12 2020 open

Let’s say you want certain individuals only to be able to post to period 1 2021, then you can enter a value in the field AUGR and then enter 1 to 1(2021). in the From and to Values of Per.2

This AUGR( Authorization group will be assigned to certain individuals in their master data in SU01- you will need to work with your security team) and these individuals only can post to period 1 2021

Another purpose of using the per.2 field is that if your books are closed for 2020 and you need to make some audit adjustments, then you can enter the from period as 13 in the per.2 field and the to period as 16 in the per.2 field.

This opens up your special periods. When you create a posting, the period field gets picked up from the posting date. e.g if your date is 12/31/2020, then the period is 12. You don’t need to manually change the period. For a special period, you will need to use any date in the last month e.g. we will enter 12/31/2020 and then change the period to 13.

When you run your reports, you will need to run them from period 1-16 to see all the postings.

Hope this helps
