Period End processing in the GL prevents posting to the closed period (unless you open GL options and set the current period backwards).  You typically want to close the GL after all the other modules though.  There is a list somewhere of the recommended module close order... maybe someone can post a link.

Can you share how I can do that? I tried exploring this but couldn't find it

How to do what?  Every module has a Period End function, with associated help files accessible by clicking the ? button in the bottom right of the panel.

Sage Knowledgebase has an article on proper period end closing procedures.  You can also find Period End Check Lists in this manner:

1. From the Sage 100 Launcher menu, click Help, then Help Topics. (window will open in default internet browser)
2. Enter "Period End Checklist" in the Search field
3. Click on the Period End Checklist for the module you need.
