Sending an order into Quickbooks via IPP doesn't work when transaction date is in the past - quickbooks

Question

I've edited the question to make it more clean and focused now that I've investigated more.
Syncing orders are working for today's date and future dates, but not for dates in the past. I'm testing now directly in the API explorer.
Here is the add order request and response:
<!--Add order request-->
<Add xmlns="http://www.intuit.com/sb/cdm/v2"

</Success>
</RestResponse>
Here is the sync status and sync activity. There was only one entity with SalesOrder, but the times don't match up, so I don't believe its referencing the same order that I added via API explorer. Also, the order that I added did not appear in Quickbooks also.
<SyncStatusResponse>
<NgIdSet>
<NgId>802721</NgId>
<NgObjectType>SalesOrder</NgObjectType>
</NgIdSet>
<RequestId>DB7F4BF877006079E040900A0F1B14C1</RequestId>
<StateCode>8</StateCode>
<StateDesc>Record netted with QB</StateDesc>
<MessageCode>70</MessageCode>
<MessageDesc>MBL Netter success using QB SDK ext_ack_id</MessageDesc>
<ResponseLogTMS>2013-04-29T15:38:02.0Z</ResponseLogTMS>
</SyncStatusResponse>
<SyncActivityResponse>
<SyncType>Writeback</SyncType>
<StartSyncTMS>2013-04-10T12:42:21.0</StartSyncTMS>
<EndSyncTMS>2013-04-29T08:38:02.0</EndSyncTMS>
<EntityName>SalesOrder</EntityName>
<EntityRowCount>20</EntityRowCount>
</SyncActivityResponse>
From the sync status response, state code 8 means
Record netted. Synchronized. Object created in Data Services. Sync Manager has acknowledged synchronizing the object and mapped its NG ID to a QB ID in QuickBooks. Equivalent to StateCode 1 (for object created in QuickBooks).
Message code 70 seems to be ok base on its description, but it wasn't listed in the documentation.

Answer 1

In Quickbooks Destop, by default only the current Fiscal year transactions are displayed. Could you try changing the Date filter to "All", to see if the Sales Order made it ?

Answer 2

So your Request is succeeding but you are not seeing it in QuicKBooks after sync is run.
Check the sync status of the object, or you can see all the sync activity by calling these APIS
http://docs.developer.intuit.com/0025_Intuit_Anywhere/0050_Data_Services/v2/0500_QuickBooks_Windows/0600_Object_Reference/SyncActivity
http://docs.developer.intuit.com/0025_Intuit_Anywhere/0050_Data_Services/v2/0500_QuickBooks_Windows/0600_Object_Reference/SyncStatus
Even though your request succeeded, before it can by synced to QuickBooks it must pass the business rules to be created/updated on the desktop.
If your object encountered an error (lets say it was a duplicate) then you can add an errored object filter on your query to query for it as well.
