Field help (TYPPST) 

This field is used to specify whether the charges accounting entries of the period must be created with a posting of the Simulation or Actual type.
By the end of a fiscal year close, the posting type of the new FY first period takes, by default, the value defined at the DEFPSTTYP - Posting type parameter level (AAS chapter, CPT group).

The Simulation posting type is available:
- on all open periods and the current period of the current fiscal year 
- on the Open periods of the following fiscal year.

In simulated posting, each charge entry generation processing related to the given period will delete and replace the potential previous entries existing in the period.
