Creating Data Driven Subscription does not allow me to get Auto copy from Query.

Question

I am trying to create a data driven Subscription for sharepoint document Library.  I have a table I populate with values.  Then a stored procedure that exec and returns the values.  I use this in my data driven subscription. 
Here is what my table looks like
intSubscriptionID strSubscriptionName strFileName strPath strRenderFormat strWriteMode strFileExt strTitle strAutoCopy strUserName strPassword strVar1 strVar2 strVar3 strVar4 strVar5 strVar6 strVar7 strVar8 strVar9 strVar10 bitEnabled
400 Billing - Invoice_ParentChildRollup 19_Jan2015 http://eagleviewportal/BusinessIntelligenceCenter/AccountingBI/Reports/New Excel Overwrite True Invoice_ParentChildRollup False NULL NULL 0000019 NULL NULL NULL NULL NULL NULL NULL NULL NULL 1
401 Test Daily Order and Pending Status by SubAccount Test Daily Order and Pending Status by SubAccount http://eagleviewportal/BusinessIntelligenceCenter/ClientRelationsBI/Reports/New Excel Overwrite True Test
Daily Order and Pending Status by SubAccount True NULL NULL 152884 NULL NULL NULL NULL NULL NULL NULL NULL NULL 1
I can use all the values and it creates my subscription no problem as long as I do not try to use the autocopy. 
If I select Use no Value  all works great. 
If I select Specify a static Value and then choose True it gives me an error The AutoCopy Delivery setting cannot be set to True if the WriteMode Delivery setting is not set to Overwrite.  as you can see that value is set to overwrite.  If I use
hard coded word OverWrite instead of getting it from query it works.
If I do the same step above but select False it seems to work as well.
If I try to choose the value from the query then it errors with the generic Sorry Something went wrong. I cannot find any value in url logs.

Hi Ken,
I have reproduced the same issue as you encountered. If you choose both value for the fields(WriteMode and AutoCopy) from query, SharePoint will result in an error page. I finally fixed the issue by manually updating the table
dbo.Subscriptions from the reporting service database. To make this, please first copy the value of field
ExtensionSettings from the subscription table.
Change the WRITEMODE and AUTOCOPY from "<ParameterValue><Name>WRITEMODE</Name><Value>Overwrite</Value></ParameterValue> <ParameterValue><Name>AUTOCOPY</Name><Value>AutoCopy</Value></ParameterValue>"
to "<ParameterValue><Name>WRITEMODE</Name><Field>strWriteMode</Field></ParameterValue> <ParameterValue><Name>AUTOCOPY</Name><Field>strAutoCopy</Field></ParameterValue>".
Here Value means the static value, and field means the name of the query field. After you modify it, copy the settings back to field
ExtensionSettings or use update SQL to update it.
At last, your data driven subscription should be like this:
