Answer:
If everything is installed on the same server then you could setup these local accounts that you have running the Application Pools to have the proper read permissions to the SSAS database by adding them into a Role with Read Definition and Read-only access to the cube(s). If you want to pass your credentials then you need to go into the web.config files in the Web Service, Preview, and SharePoint directories and modify the Bpm.ServerConnectionPerUser value in the AppSettings to True so that the credentials of the current logged in user will be passed to the database.If you are in a distributed environment then you will have to look at configuring Kerberos, Configuring Kerberos Delegation with PerformancePoint Monitoring Server, or using the CustomData option outilined here - PPS Data Connection Security with CustomData.

MDX CrossJoin Rows and Columns

This Sample will help you to understand How to applay Cross Join for Dimension meber( Rows and Columns)

Measures:
Payment Amt, Curr Payment

Rows : Vendor Name, Vendor Group are Rows
Columns : Month Name.

To Find Grand Total for Each Group :

[Vw Payment Details].[Vend Details].[Vend Details] .Members
[Vw Payment Details].[VENDGROUP].[VENDGROUP].Members
This Will give the value for each VendorName ,Vendor Group and Grand Total of Each Vendor Group.
Note ** But It will not give the [Grand Total] All the Vendor Groups

To Find Grand Total for ALL Group

1. Create Named Members
MEMBER [Vw Payment Details].[Vend Details].[Grand Total]ASAGGREGATE([Vw Payment Details].[Vend Details].[Vend Details] )MEMBER [Vw Payment Details].[VENDGROUP].[Grand Total]ASAGGREGATE([Vw Payment Details].[VENDGROUP].[VENDGROUP] )

2. Call the Member Inside the Query

({[Vw Payment Details].[Vend Details].[Grand Total]}
,{[Vw Payment Details].[VENDGROUP].[Grand Total]})









WITH
MEMBER [Vw Payment Details].[Vend Details].[Grand Total]
AS
AGGREGATE([Vw Payment Details].[Vend Details].[Vend Details] )
MEMBER [Vw Payment Details].[VENDGROUP].[Grand Total]
AS
AGGREGATE([Vw Payment Details].[VENDGROUP].[VENDGROUP] )
SELECT
CROSSJOIN(
{ [Time].[Fiscal Period].[Year].&[2009]&[2009 - 2010].&[2]&[May]
, [Time].[Fiscal Period].[Year].&[2009]&[2009 - 2010].&[1]&[April] }
, { [Measures].[Payment Amt], [Measures].[Cur Payment Amount] }
)
ON COLUMNS
,
{
CROSSJOIN({[Vw Payment Details].[Vend Details].[Vend Details] AS [Vendor Name] }
,{[Vw Payment Details].[VENDGROUP].[VENDGROUP] AS [Vendor Group]}
)
,(
{[Vw Payment Details].[Vend Details].[Grand Total]}
,{[Vw Payment Details].[VENDGROUP].[Grand Total]}
)
}
ON ROWS
FROM [Axapta Payment Details]

SSAS MDX Query Last Transaction Date , Count Payment Due

This Post will help you to Find the Payment Due of Vendors.
Here the Idea is Find the Last Transaction date and Last Date of Seleted Period Then subtract between this.
This is done using -[Measure].[Day Count] Row Count of DimDate.Date column
And i explained some different behaviour of this.

1. Find LastDate Over Period(Selected Time Period)
This Measure is Derived from Date Dimension Table.
Ex. Select Year 2009 in filter and select some Months in column then
Result is :
January : February :March
31/1/2009 ;28/2/2009 ;31/3/2009

TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0).Name

2. Last Transaction Date Over Period

Ex: Selected Month is Jan then
(Date >= Jan - 1 - 09 and Date <= Jan - 31 -09)

TAIL(NonEmpty(EXISTING [Date].[Date].MEMBERS, [Measures].[Amount])).ITEM(0).NAME

3. Last Transaction Date From Current Period to Previous Periods
Ex: Selected Month is Jan then (Date <= Jan - 31 -09)
Find the Transaction Date Between
1. All the Previous Periods : NULL
2. Tail Member : TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0)
3. Look up Measure Between this Date and get the Tail Member

TAIL(
FILTER(
(NULL : TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0))
, NOT ISEMPTY([Measures].[Amount])
)
).ITEM(0).Name

4. Count Payment Due
Count Date Between Last day of Each Period to Last Transaction Date of Previous Period to the Current Period
Step 1:
First Find the [Measures].[DayCount]
[Measures].[DayCount] :- Count Rowl Measure from DimDate.Date Column
Step2:

I).From : Last Date of Period (Jan - 31 -09)
II). To: LastTransactionDate(NULL : (all previous Member) and Date <= Jan - 31 -09)

III). Sum of DayCount Between the Period

SUM(
{ TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0)
:
TAIL(
FILTER(
(NULL : TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0))
, NOT ISEMPTY([Measures].[Amount])
)
).ITEM(0)
}
,[Measures].[DayCount]
)

5. Count Payment Due from Last Transaction Date To Last Date of current Period
Ex:
1.From : Last Date of Period (Jan - 31 -09)
2. To: LastTransactionDate(Date >= Jan - 1 - 09 and Date <= Jan - 31 -09)
3. Sum of DayCount Between the Period


SUM(
{ TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0)
:
TAIL(NonEmpty(EXISTING [Date].[Date].MEMBERS
, [Measures].[Amount])).ITEM(0)
}
,[Measures].[DayCount]
)


****************
Sample Query
****************

WITH
MEMBER [Measures].[PaymentDue Previous Period] AS
SUM(
{ TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0)
:
TAIL(
FILTER(
(NULL : TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0))
, NOT ISEMPTY([Measures].[Amount])
)
).ITEM(0)
}
,[Measures].[DayCount]
)
MEMBER [Measures].[PaymentDue Over Period] AS
SUM(
{ TAIL(EXISTING [Date].[Date].[Date].MEMBERS).ITEM(0)
:
TAIL(NonEmpty(EXISTING [Date].[Date].MEMBERS
, [Measures].[Amount])).ITEM(0)
}
,[Measures].[DayCount]
)

SELECT {[Measures].[PaymentDue Previous Period]
,[Measures].[PaymentDue Over Period]
}
ON ROWS,
[Date].[Month Name].MEMBERS
ON COLUMNS
FROM [Vendor Ledger]
WHERE ([Date].[Year].&[2008],[Vendor].[Vendor].&[10006])

In this example [Measures].[PaymentDue Over Period] will fit in to real time

Create Dynamic Time Dimension Named Set in SSAS

This post will explain that How to create the Time Dimension Dynamic named set using CurrentDate .

Most of the people might have know about this. This post is for self reference and sharing the knowledge.

In My cube I have Calandar Time Hierarchy
My Hierarchy is
[Year] -> [Quarter] -> [Month] -> [Day]
Here i explained some Named Set.

1. [Last years]
2. [Last Quarter]
3. [Last Months]
4. [Last Days]

Step1: First Find the Time Dimension Hierarchy Member from your cube, and select the Hierarchy member inside your Query Window.
MemberName of Year,Quarter,Month,Day :
[Date].[Time].[Year].&[2009]
[Date].[Time].[Year].&[2009].&[2]
[Date].[Time].[Year].&[2009].&[2].&[5]
[Date].[Time].[Year].&[2009].&[2].&[5].&[15]

Now you will get this query.

Step2:
Frame the string member as it is in the step1. then create the Name set by using [New Named Set] in the cube Calculation Tab.

The following link will help you to derive DateParts from Current Date.
http://www.ssas-info.com/analysis-services-faq/27-mdx/78-how-write-mdx-query-that-uses-execution-datetime-now-as-parameter

1. [Last Years]

LASTPERIODS(3, StrToMember("[Date].[Time].[Year].&["
+ Format(Now(), "yyyy")
+ "]"))

2.[Last Quarter]

LASTPERIODS(4, StrToMember("[Date].[Time].[Year].&["
+ Format(Now(), "yyyy")
+ "].&["
+ cstr(datepart( "q", Now()))
+ "]"))

3. [Last Month]

LASTPERIODS(6, StrToMember("[Date].[Time].[Year].&["
+ Format(Now(), "yyyy")
+ "].&["
+ cstr(datepart( "q", Now()))
+ "].&["
+ Format(Now(), "MM")
+ "]"))

4.[Last Day]


LASTPERIODS(30, StrToMember("[Date].[Time].[Year].&["
+ Format(Now(), "yyyy")
+ "].&["
+ cstr(datepart( "q", Now()))
+ "].&["
+ Format(Now(), "MM")
+ "].&["
+ Format(Now(), "dd")
+ "]"))

here you can define the lastperiod as your wish.

SSAS Cube Processing Using .Net CLR StoredProcedure

There are 3 ways to Process the SSAS 2005 Cube:
1. AMO(Analysis Management Objects) with .Net CLR Procedure
2. Power Shell Script
3. SSIS ETL Package.
Here i explained my Experience with

[1.] AMO(Analysis Management Objects) with .Net CLR Procedure this is More flexible and easy to handle Cube Objects.

Step 1.Enable CLR in SqlDataBase

SP_CONFIGURE 'CLR ENABLED',1 GO RECONFIGURE

Step2. Create New .Net DataBase SqlServerProject(CLR Project) with your Required DataBase connection














Step3: Create Microsoft.AnalysisServices.DLL" Reference in [Cube Processing] Project

1. Find "Microsoft.AnalysisServices.DLL" in C:\Program Files\Microsoft SQL Server\90\SDK\Assemblies\ and copy paste to some Folder D:\CLR Project\

2. Register Assembly in SQLServer DataBase

CREATE ASSEMBLY [AnalysisServices]
FROM D:\CLR Project\Microsoft.AnalysisServices.DLL'
WITH PERMISSION_SET = UNSAFE

3. Refer [AnalysisServices] Assembly

Right click [Cube Processing] Project and click Add Reference and Select "Sql Server Tab" select

[AnalysisServices] Assebly.


Note1. Assembly will be avaliable in "SqlServer Tab" only after Creating Assembly in Datbase .
as well as it can be seen in SQLManagementStudio -> Database->Programmabillity -> Assembly




Step 4: Create Method ProcessPartition Using Microsoft.AnalysisServices Classs

/*
Process the Cube Partition using given Input Parameter Values. If ProcessDimensions is True then
process all MeasureGroup Related Dimension
-- Simple Code and Commented Briefly
*/

1. Copy Paste the code

using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using Microsoft.AnalysisServices;
public partial class StoredProcedures
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void ProcessPartition(SqlString ServerName, SqlString CatalogName, SqlString CubeName, SqlString MeasureGroupName, SqlString PartitionName, SqlBoolean ProcessDimensions)
{
try
{
// Create Instance for AnalysisServer
Microsoft.AnalysisServices.Server svr = new Microsoft.AnalysisServices.Server();
// Create Instance for MeasureGroup
MeasureGroup measureGroup = new MeasureGroup();
// Connect Analysis Server Instance
svr.Connect(ServerName.ToString());
if ((svr != null) && (svr.Connected))
{
// Connect the Analysis Server DataBase
Microsoft.AnalysisServices.Database db = svr.Databases.FindByName(CatalogName.ToString());
Cube cub;
// Find the Analysis Server DataBase Cube
cub = db.Cubes.FindByName(CubeName.ToString());
// Find the Analysis Server DataBase Cube MeasureGroup
measureGroup = cub.MeasureGroups.FindByName(MeasureGroupName.ToString());
// Check ProcessDimensions Flag If its True Process All MeasureGroup Related Dimesnion
if (ProcessDimensions == true)
{
foreach (MeasureGroupDimension Dim in measureGroup.Dimensions)
{
// Proces Dimension
Dim.Dimension.Process();
}
}
// Find the Analysis Server DataBase Cube MeasureGroup Partttion
Partition par = measureGroup.Partitions.FindByName(PartitionName.ToString());
// Process Partition
par.Process();
}
// DisConnect Server Connection
svr.Disconnect();
}
catch (Exception Ex)
{
// To Send Error Message to Database
SqlContext.Pipe.Send(Ex.Message);
throw new ApplicationException(Ex.Message);
}
}
};

/*
This code will process the Cube up to low Level object. If you wish to Process only the DataBase,Cube,MeasureGroup then
use DataBase.Process(),Cube.Process(),MeasureGroup.Process() .
*/

2. Build the Project
3. Copy the [Cube Processing] DLL from Solution \bin\Debug folder and Paste to D:\CLR Project\
4. Create Assembly in SqlServer DataBase:

CREATE ASSEMBLY [Cube Processing]
FROM 'D:\CLR Project\Cube Processing.dll'
WITH PERMISSION_SET = UNSAFE

5. View the Assembly
Now the Registered [Cube Processing] Assembly wl be abaliable in SQLManagementStudio -> Database->Programmabillity -> Assembly

Step5: Create Extented StoreProcedure Using Registed Assembly (Cube Processing])

CREATE PROCEDURE [dbo].[ProcessPartition]
(@ServerName NVARCHAR(50)
, @CatalogName NVARCHAR(50)
, @CubeName NVARCHAR(50)
, @MeasureGroupName NVARCHAR(50)
, @PartitionName NVARCHAR(50)
, @ProcessDimensions BIT
)
AS
EXTERNAL NAME [Cube Processing].[StoredProcedures].[ProcessPartition]

[Cube Processing] -->Registered Assembly Name
[StoredProcedures] --> Class Name of the above Code
[ProcessPartition] --> Method Name of he Class


Step6: Execute Procedure [dbo].[ProcessPartition]

EXEC [ProcessPartition] @ServerName = 'MyServer\Instance1'
, @CatalogName = 'MyDatabase'
, @CubeName = 'MyCube'
, @MeasureGroupName = 'MyCube'
, @PartitionName = 'MyCube_2008_08'
, @ProcessDimensions = 1

Unexpected error occurred while Open CalculationTab in SSAS Cube

In Business Intelligence Development Studio (BIDS), when i am in Analysis Services Project and when i open a cube and select the calculations tab, the design surface displays a message that reads:
Unexpected error occurred: 'Error in the application' and then it closes Visual Studio.

Found Mary Potapova's answer in the Microsoft Forum very useful as it fixed my problems. I quote here fix:
this might be caused by version mismatch between some binaries. i'd suggest checking the versions of msmdlocal.dll and msmgdsrv.dll and making sure that the ones installed into %ProgramFiles%\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies\ are the same as those in %ProgramFiles%\Common Files\System\Ole DB\ (if they are not then try updating the ones in the PrivateAssemblies with the ones from ole db; you might want to save the original ones as to be able to get back to original state just in case.. It helped me to fix this issue.
