Not able to change a system view through the UI : vNotificationOpportunity

Hi all,

I have a problem : I've added a notification on Opportunity entity, but when the rule is executed it generates the following error :

Error SQL : Cannot create a row of size 8559 which is greater than the allowable maximum row size of 8060 (select * from vNotificationOpportunity WITH (NOLOCK) WHERE ( oppo_lab_level = 'L2') AND ((Escl_EscalationId is NULL ) OR (Escl_WorkflowRuleId <> 10221 ) OR ((Escl_WorkFlowRuleId = 10221 ) AND Escl_Datetime <'20140908 10:14:44' )) ORDER BY oppo_opportunityId)
Sep 8 2014 10:14:45.135 8776 8632 1 NotifyException,10221,WkRl_WhereClause: ( oppo_lab_level = 'L2') AND ((Escl_EscalationId is NULL ) OR (Escl_WorkflowRuleId <> 10221 ) OR ((Escl_WorkFlowRuleId = 10221 ) AND Escl_Datetime

Ok sounds like I have to change the view and specify manually all the fields I would need (and don't forget all "system fields" like created by, channel id, etc.).

BUT even though I'm able to change other system views, I don't know why this vNotificationOpportunity don't show any "Change" button on the Customisation/Views screen. ???


So I need help to be able to update manually the SQL request directly inside the Database : I've found it inside Custom_Views table, but I need advise not to forget any step (maybe I need to update the view somewhere else, or I need something more than a refresh metadata after that update).

Please help ! :)

Thank you
