Error when closing the period

Hi, 

You must define those posting types in posting control window. 

Accounting Rules > Posting Rules > Posting Control

If you are not sure what account to use then I can suggest you 2 things.

1. Go to company template and find the template your company created by.  Navigate to company template component. Select the component that posting control belongs to. Go to logical unit posting control and you can find there what account is matched to the posting control. You can replicate it in posting control window. See example below

2. If your company is not based on any template then you can go to template STD (like below sample), find the matching accounts and then go to ACCRUL component to see the names of the matched accounts along with logical account types. Create those accounts in your company and define posting controls.

Hope it is clear and helpful.
