I have a Date Dimension called Dim_Date in my Data Warehouse. Now the issue is that my Date Dimension is only populated till 31st Dec 2011. My cube is built in SSAS. Is there any way I can populate my Date Dim for another 5 years? When I try to Process my Date Dimension from SSAS it does not populate any values. SO what is the best way to insert 5 years value into my date dimension?
Please Help
Cheers

You could use an ETL tool (e.g. MS SSIS) for generating data for date dimension table. There is multiple examples for this, google is your friend.

In the process of creating a new cube for my client, I encountered a problem I'm not sure hot to deal with.
I have a table that doesn't have a DateTime field; instead it has a varchar field which contains year and month in YYYYMM format. I need to create a relation to my Time dimension using that field; and proceed with creating Year-Quarter_Month hierarchy.
First thing I did was creating a new named calculation in Time table from the date field to match the YYYYMM format. Now, I understand that the relation can't be created because it would break the referential integrity.
My idea is to create a new Time table/dimension and delete all records except the first day of the month, create a YYYYMM named calculation and then I would be able to create a relation between my table and that new Time table. But, is this the right approach and what downsides I can expect?
Thank you!
You don't need a separate time dimension...when connecting the new fact table to the existing time dimension (in the dimension usage tab) you can set the YYYYMM attribute as the "granularity attribute"...SSAS will handle the rest :-)
Also, if the format is YYYYMM (ie. 201504 for april 2015) then you might consider making it an integer (instead of a varchar) to save some space in your fact table.
You can create a new calculated column in that table to add the first day of the month:
convert(date, YYYYMMfield*1000+01)
and then link it with your key in your time dimension.
This way, your YYYY-QQ-MM hierarchy levels work as intended, if the user is going deeper and wants to see monthly values on a daily basis, he will find all values for that month added to the first day.
I have a separate date dimension marked as Date table in Tabular Model and having proper relationship with another table(e.g SalesTable) with column of date type. But still time intelligence functions are not working. I am using the date column from other table (e.g SalesTable) in the formula.
I'm not sure what exactly is going wrong in our tabular model. Can someone give any insights?
Thanks,

You have to use the date column from your date table in your formulas. For example
PrevMonthAmount:=CALCULATE(SUM([Amount]),PREVIOUSMONTH('Date'[Date]))
Also, time intelligence doesn't work in direct query mode, on the chance that you are using that mode.
This is a good intro to time intelligence:http://www.mssqltips.com/sqlservertip/3075/sql-server-analysis-service-dax-time-intelligence/
I need to create a SSRS report where the user specifies the start and end date (e.g. March 2012 to July 2012) and the result is a report with the following headings:
User Department Product Mar-12 Apr-12 May-12 Jun-12 Jul-12
The dates are stored in a datetime column (e.g.2012-06-11 14:48:04.787) in my SQL table which I'm using to build the time-series report.
Do I need to convert/transpose my SQL table first? Or should I be processing this in SSRS?
Your advice is much appreciated!
Based on your question it appears all your dates are in a single datetime column and your trying to display them, formatted as a month, in a single report with the report columns grouped and renamed based on the month. This is a pivot and I don't think you can do that within SSRS. The dataset will already need to be pivoted by the time SSRS gets it.
So, to me this sounds like something you'll have to do both pre and post SSRS. I did a similar report using days of the month. You can see the winning answer here. as opposed to months of the year.
Thinking through your logice, I think you'll probably have to build the query with the pivot and then send to SSRS. On the SSRS side you need 12 columns for all 12 months and then put some logic to hide the ones that don't get data. Your original pivot will need to be smart enough to pass the empty months so SSRS doesn't error out. The end result will appear the same but needs a lot of pre-thought and design effort up front.
You do the processing using SSRS - you would design it in the GUI editor(BIDS ) , and you can customize things using the VBasic code also(i.e, dates and logic)
Looks like you need an intro, I really recommend this video
I have an SSAS cube with time as one of the dimention.It contains hierarchy like year-quarter-month etc.When i drag and drop the this on SQL Server Managment Studio window(brows), it looks like data is repeating.For example,year is like 2002,2002,2003,2003,.. etc.If i expand first 2002 i can see 1st quarter under that.If i expand second 2002 i can see 2nd quarter etc..Can any one tell what is the reason? how can i change to single data?
First of all are you using your own Date Dimension table. If so, make sure you use the correct key for Date, Month, Quarter and Year. For example, normally the date dimension has YearMonth column used as the key for the Month attribute (eg 2012-04). If you don't have such a column you will need to pick a composite key for Month (Year and Month). Also, a good way to check is in the dimension designer in BIDS go the browser tab of the dimension and make sure the hierarchies are showing up fine.
I have a T-SQL view with integer fields. I need a report on a monthly basis regarding the difference from one month to the next, i.e. so many people were engaged in a particular activity on 8am of the 1st of this month, so many the previous month, here is the difference. The numbers fluctuate all the time. I need a variance between 2 snapshots in time.
I am using the SSRS, however in reporting services I can only display the "current" situation. I could run a report at 8am of the 1st of each month and then calculate the differences manually. But how could I automate this calculation and then report on the difference?
I have tried to import data from SQL to 1 Excel spreadsheet from 1 month, then to the 2nd spreadsheet from the 2nd month. The 3rd spreadsheet calculates the difference. But how do I create a nice looking report from Excel?
Additionally I cannot send the report by email. It has to be available online.
Furthermore, each office wants their figures to be confidential and not visible to another office.
Thanx in advance.
Can you add a UserCount table that stores each office's user count for each month? It could have columns like:
id
date
user_count
office_id
You would insert a new row each month based on what the view tells you that month for each office. Then it's as simple as exporting that table to Excel and graphing it using Excel's built-in graphing tools.
