KB2490555 - FIX: Data update does not occur daily in SQL Server 2008 R2 PowerPivot for SharePoint if business hours are set to end the next day

Symptoms

Consider the following scenario:

• You install and configure Microsoft SQL Server 2008 R2 PowerPivot for SharePoint on a computer.
  

• You publish or upload an Excel PowerPivot workbook to the PowerPivot gallery.
  

• You configure the PowerPivot service application settings to define business hours that cross the boundary of a day. For example, you specify the start time of the business hour to 6:00 AM and the end time to 2:00 AM of the next day.

• You enable data update for a workbook.

• You schedule data update to run daily and to the After business hours earliest start time.

In this scenario, data updates every other day instead of every day.

Cause

This issue occurs because Microsoft SQL Server PowerPivot for SharePoint handles the next schedule run incorrectly.

Resolution

Workaround

To resolve this issue, apply the cumulative update if you meet one of the following conditions:

• You do not have a PowerPivot Service application.

• You can drop the existing PowerPivot Service application, and then you can create a new one. 
  

If you already have a PowerPivot Service application, and if you cannot drop and then create a new one, run the following Transact-SQL script to work around this issue. This script updates the [DataRefresh].[ProcessNextScheduledRun] stored procedure against the PowerPivot service application database.

IF OBJECT_ID ( '[DataRefresh].[ProcessNextScheduledRun]', 'P' ) IS NOT NULL 
    DROP PROCEDURE [DataRefresh].[ProcessNextScheduledRun];
GO

-- The caller should update the [NextProcessDate] and set the status to 'P'.
CREATE PROCEDURE [DataRefresh].[ProcessNextScheduledRun]
@AllotedServerName [nvarchar] (256)
AS
DECLARE @CurrentTime datetime;
DECLARE @CurrentDate datetime;
SET @CurrentTime = GETDATE();
SET @CurrentDate = [DataRefresh].[DateOnly](@CurrentTime);
SET @CurrentTime = [DataRefresh].[TimeOnly](@CurrentTime);
-- Caller will calculate virtual run window and cancel the run that missed it.
UPDATE [DataRefresh].[Runs] SET [RunStartTime]=GETDATE(), ResultKey='Q', ServerName=@AllotedServerName
OUTPUT inserted.*
WHERE [RunID] 
in (SELECT TOP 1 [RunID]
FROM [DataRefresh].[Runs] 
WHERE ResultKey='W'
AND 
(
(
-- AfterBusinessHour cases that haven't been loaded to verify IT overridden business hours.
-- To handle IT overridden business hours, we will process after business hours schedules immediately 
-- and set [ProcessStartTime] and [ProcessEndTime] for the schedule and create other schedules if it is necessary.
[ProcessStartTime] IS NULL 
) 
OR
(-- None AfterBusinessHour cases
ProcessEndTime IS NULL 
AND ( @CurrentTime>=[DataRefresh].[TimeOnly]([ProcessStartTime]) OR DATEDIFF(Day, ProcessDate, @CurrentDate)>=1)
)
OR 
(
-- BusinessHours setting crosses the day boundary.
[DataRefresh].[TimeOnly]([ProcessStartTime])<[DataRefresh].[TimeOnly]([ProcessEndTime])
AND (
DATEDIFF(Day, ProcessDate, @CurrentDate)>1 
OR
(DATEDIFF(Day, ProcessDate, @CurrentDate)>=0 AND @CurrentTime>=[DataRefresh].[TimeOnly]([ProcessStartTime]))
)
)
OR
(
-- BusinessHours setting within the day boundary.
[DataRefresh].[TimeOnly]([ProcessStartTime])>[DataRefresh].[TimeOnly]([ProcessEndTime])
AND ( @CurrentTime>=[DataRefresh].[TimeOnly]([ProcessStartTime]) OR DATEDIFF(Day, ProcessDate, @CurrentDate)>=1)
)
-- The following case has been coverred.
--OR
--(
---- Very old runs that haven't been picked up.
--DATEDIFF(Day, ProcessDate, @CurrentDate)>1
--)
)
ORDER BY [ProcessDate] ASC
)
GO

GRANT EXECUTE ON [DataRefresh].[ProcessNextScheduledRun] TO [GeminiService_DataRefresh]
GO
