Is there a table(s) that SAP uses to determine unsettled amounts?

Hi Experts,

We are trying to determine how SAP determines which transactions have been settled for determining what it must settle. What is the table (not a report using i.e. -  CJI3 using balances, dates, and business transactions) that can be used to determine that SAP has settled or has not settled a particular posting with respect to a particular WBS or a maintenance order?

Here is an example:

WBS A or Order Z

Posting date 6/1/16     GL acct X     Amt $100     Bus Trans COIN                Represents a posting to a WBS or order

Posting date 6/2/16     GL acct X     Amt - $100     Bus Trans KOAO             Represents a settlement from a WBS or Order

What table does SAP use to determine how a posting to the WBS or order has been settled or not been settled.

Thank you,

Kevin
