Writing into F42199 Ledger records

Hi,

I want to try to understand how the Ledger records are written when there is a change in the Order status.

The Order Activity rules setup is as shown below

When a SO/S is created, the Order Status will be Last Status = 520 and Next Status = 540.

When checking in the VerifyActivityRuleStatusCode B4000260.C business function, only Next Status is passed instead of Last Status.

In my scenario, I want to turn off the WriteLedger Flag for 520/540 status (Order Creation) and I expect there are no lines inserted into the Ledger.

But, the system checks in Order Activity rules for Last Status = 540. As the WriteLedger Flag = 'Y', records are inserted into the Ledger.
