问题 There is a Sales Invoice dimension which is related to Sales measures. Sales measures are partitioned. I have 2011 partition and 2012 partition. I figured that we don't need to process Sales 2011 partition because it doesn't change anymore. Unfortunately (confirmed by "impact analysis") after reprocessing of Sales Invoice dimension my both Sales Measure partitions become Unprocessed. Is there a way to avoid that? Please note that primary key doesn't change. Processing takes place in SSIS

问题 We are implementing Power BI with SSAS Cube Direct Query. For some reason, SSAS Power BI is extremely slow performance, however using SSDT SSAS Application or Power View or Excel is Much faster. I read that Power BI converts SSAS Multidimensional models by converting MDX to a DAX query. Is there any method to speed up Power BI queries for SSAS, or use MDX queries directly? We are applying SSAS Multidimensional model. 回答1: I don't think that the performance issue is caused by converting MDX

问题 We have implemented row level security in our SSAS database. In our business case we have property level security and account level security. In property level security user should be able to see data for only those properties which are assigned to him, and in Account Level security a user should be able to see data of only those accounts for which he is authorized to access. After security implementation we noticed a problem due account level security implementation, users were not able to

问题 I have a dimension called customer, with UnknowMember = True and UnknowMemberName = NA. When I process my dimension, I see all my customers plus a NA member. I also configured ErrorConfiguration = IgnoreError and KeyErrorLimit = 100 I have a row on my fact with NULL on the customerID and the Cube fails to process with this error (its changing NULL to 0, not sure if it is expected): Errors in the OLAP storage engine: The attribute key cannot be found when processing: Table: 'dbo_FactSales',

问题 In order to give a nicer Cube browsing experience to end users, I am trying to create a Time Periods hierarchy consisting of Calculated Members. Currently I have used a Calculated Column in my DSV to create a column with the same value on every row in my Dates table (value is All Time ). Then within my Date and Time dimension I have created a single level, single member hierarchy using that Calculated Column, which looks like this: Now what I have already successfully done is add Time Periods

问题 I am using Visual Studio 2013(C#) and SSAS 2014 (through AMO). I need to prepare a list of permissions of a given user in the SSAS database. For example, domainName\userName has permissions on the 2 dimensions out of 5 available in the database. I like to prepare a list like this. Dimension Name | Attributes | Dimension used in Cube | VisualTotal | Mdx Set (if any) | Role Name I can loop through Roles and members and get some information. But it seems that it is a long shot and will not be

问题 As is usual with cubes, the users want things that don't fit into a hierarchy to be displayed hierarchically. They'd like to see Day > Week > Month > Quarter > Year as the hierarchy, but the problem with weeks is they can be part of 1-2 months, not just 1 month (and by extension part of 2 quarters, semesters, years). So my question is: how to set up the attribute relationships, and how to set up the hierarchy? Here is what I have, but I know it's not optimal. Hierarchies (cycle == weeks):

问题 I am having some issues trying to implement an average of a dimension attribute. The basic structure is: Booking Header Dimension Fact Table (multiple rows per Booking Header entry) On the booking header dimension I have a numerical attribute called Booking Window, and I want to be able to create a calculated measure that averages this value. We are using SQL Server 2012 standard edition. Any help would be greatly appreciated. 回答1: The best approach would be to create a measure group from the

问题 I am relatively new to this depth of MDX, but here is my dilemma. My goal is to implement a calculated member using a .Net Stored Procedure. The calculation (XIRR) will be based on a set of cash flow dates and cash flow amounts. Ideally this would be a calculation in my cube that is available as a measure to Excel/Browser users. So to start simple I am just trying to implement my own COUNT calculated member/measure (not even using .Net) to say count the # of members in a given dimensions
