Little bit of background, we have an OLAP system that has been happily processing it's cube for a customer for a long time. Then recently it started to fail. This has coincided with the main developer accidentally getting married and making himself unavailable. So obviously I can't go pestering him.
We have a date dimension that works at Year, Month, Day level. We have thow hierarchies for calendar and fiscal years.
It's currently throwing a message that I find pretty indecipherable (not being an OLAP dev) and the examples I've read online refer to it being caused by weeks splitting across months, which is not a problem I have. The message is:
Rigid relationships between attributes cannot be changed during incremental processing of a dimension.
When I reprocess the cube I now get problems related to dates. When I reprocess the Date dimension I get the following:
Internal error: The operation terminated unsuccessfully.
Errors in the OLAP storage engine: Rigid relationships between attributes cannot be changed during incremental processing of a dimension.
Errors in the OLAP storage engine: An error occurred while the 'Date ID' attribute of the 'Date' dimension from the 'TMC_CUBE_TESCO' database was being processed.
Errors in the OLAP storage engine: The process operation ended because the number of errors encountered during processing reached the defined limit of allowable errors for the operation.
Server: The operation has been cancelled.
When I view the entire detail for the Date Dimension I see that it has processed a heap of SELECT statements but falls down here:
SELECT DISTINCT [dbo_dw_DIMdate].[DateTime] AS [dbo_dw_DIMdateDateTime0_0],[dbo_dw_DIMdate].[DayOfMonth] AS [dbo_dw_DIMdateDayOfMonth0_1],[dbo_dw_DIMdate].[MonthNumberCalendar] AS [dbo_dw_DIMdateMonthNumberCalendar0_2],[dbo_dw_DIMdate].[YearCalendar] AS [dbo_dw_DIMdateYearCalendar0_3]
FROM [dbo].[dw_DIMdate] AS [dbo_dw_DIMdate]
Processing Dimension Attribute 'Date ID' failed. 1 rows have been read.

I'm not after "sent me teh codez", but any help understanding the error message and problem would be very much appreciated.
