问题 I am trying to implement ASP.net application which will need to connect Microsoft Analysis Service (SSAS) to retrive data from cube as well as dimensions. static void Main(string[] args) { StringBuilder connectionStringBuilder = new StringBuilder(); connectionStringBuilder.Append("Data Source=MyDataSource;"); connectionStringBuilder.Append("Initial Catalog=MyOlapDatabase;"); connectionStringBuilder.Append(@"User Id=OlapServerMachineName\MyUserName;"); connectionStringBuilder.Append("Password

问题 So we process the SSAS tabular cubes every night and the other night the processing of the cube failed. Now what I want to do is implement a system that would trigger an automatic reprocess after failure. Is there a way to do that in SSAS Tabular? 回答1: Nothing built into SSAS will automatically restart processing on error. In SQL Agent, the Job Step Properties dialog has an Advanced tab with a Retry Attempts property. If you change that to 1, then it will automatically retry the step (the

问题 Sometimes when I deploy a cube that has been changed (from BIDS), I can continue to browse the existing cube data. Other times, the engine insists I reprocess the data before I can browse the cube. I can't find a definitive resource showing which changes require a data reprocess and which do not. SSAS 2008. 回答1: In general, you need to process when adding or editing measures adding a dimension attribute editing dimension attribute relationships or order by properties A more complete list can

问题 I have read about aggregation design tab in ssas.It is telling we can precalculate the aggregation and it will improve the response time.But when i tried that option,i haven't go thorough any step which is showing what kind of aggregation(eg:sum,avg etc) we have to do.In one of the steps, there is an option of specifying count of rows.So aggregation means only count of rows in table? Other than this we know,there is one calculated measure option using we can specify sum or avg or etc.This

问题 I have a Cube with a date hierarchy (year, quarter, month, day) and I also have set up attribute relationships for this hierarchy. When I browse the cube with excel and make a pivottable, I can not use for example only the month attribute in the rows. When I drop the month in the rows, the entire date hierarchy shows up in the pivottable. I don't want this, I just want the month showing up. please help 回答1: Right click on a year and choose Show/Hide Fields. Then uncheck the Year level and any

问题 I have two time dimensions, production period and accounting period, and a measure that I want to aggregate with either dimension but not with both when users query the cube from excel. To do that I created a flag measure to check if both dimensions are being used CREATE MEMBER CURRENTCUBE.[Measures].[AcctProdFlag] AS IIF ( [DIM Accounting Period].[Accounting Period Hierarchy].CURRENTMEMBER.level.ordinal <> 0 and [DIM Production Period].[Production Month Hierarchy].currentmember.level.ordinal

问题 If I create a set of tuples via the following crossjoin which hierarchy is joined to which first? hierA * hierB * hierC If I know that the count of non empty members in A and B are significantly less than the count of members in C then should this influence the order? 回答1: It depends on the execution system used, i.e. how crossjoining on axis is optimized by compiler. Anyway, you will get real boost only if you first reduce cube size with subselect - it will prevent crossjoining non-matching
