How to tune performance of a cube with multiple date dimension?

Hi,
I have a cube where I have a measure. Now for a turn time report I am taking the date difference of two dates and taking the average, max and min of the date difference. The graph is taking long time to load. I am using Telerik report controls.
Is there any way to tune up the cube performance with multiple date dimension to it? What are the key rules and beset practices for a cube to perform well?
Thanks,
Amit

Hi amit2015,
According to your description, you want to improve the performance of a SSAS cube with multiple date dimension. Right?
In Analysis Services, there are many tips to improve the performance of a cube. In this scenario, I suggest you only keep one dimension, and only include the column which are required for your calculation. Please refer to "dimension design" in
the link below:

It would be helpfull if you actually created an <img> tag to start with

would work.

Optimizing order by query with multiple time dimensions

Hello all,
I have two time dimensions, one a standard date dimension (Year,Qtr, Month, Week, Day) the other a user defined Time dimension (All, Hour, Minute, Second).
I am joining my cube with my time dimension using only the 'All' level, so that I can get a single record for the Day level in my Date dimension. Under these circumanstances there aren't many records in my sample data. Less than 100 dates, although at the lowest level(seconds) there are approx 2 million records.
In order to get my results back in order I am ordering by the date dimension day_end_date. The query is taking longer than I would expect given that there aren't many records at the Day Level. How can I ensure that my query is ordering based only on the values in the current day_level and not all day_end_dates values in the underlying cube.

Changed order, speed improved significantly.

Convert a scatter graph with multiple data series into individual graphs

I am trying to convert a scatter graph with multiple data series into individual graphs, with the series having the same formatting as in the graph when all series are together.
Normally, if I delete any series, the color scheme for all the other series vanishes. I can then waste more time in having to re-adjust the color and shape of the series, but this is tedious. This, I do not want. Is there an automated way to do this?
Ideally, of course, all series would appear in little subsections in the space of the former one graph, all with individual axes, but I can't have all, so I'll settle with having several individual new graphs, each with just one series, and with the original
formatting.
Thx.

How about creating a copy of the chart, and then setting all series except one to be transparent (no line, no marker)? Repeat for each series.

Adhoc Query Requirement with Multiple Data Source

Hi All,
I have a Adhoc Query Requirement with Multiple Data Source. Is there any way to achive it. Other than Resultant set and bring into Model.
Thanks
SS

You can compare stuff in the EL, but I don't think this is what you need.
You can just use Java code in the backing bean class for all the business logic. You can use DAO classes for database access logic. Finally for displaying you can use the JSF tags such as h:outputText.

Publication for Deski report with multiple data providers

Hi,
Has anyone been able to get a publication working that uses a Deski report with multiple data providers as the source? I'm trying to get a publication working that uses dynamic recipients and personalization. When I try to schedule the publication, I get the error "Object not found".
Thanks,
Debbie

Debbie,
That's standard.
It's useful for emulating outer joins in reports.
Say you've got a sales report where you want to display all 12 months of the year in a crosstab whatever month you run in.
We're only in May at the moment though. With one data provider (SALES), you'll get a crosstab with just up to May for your months.
If you create a separate data provider called MONTHS to return the months in the current year, you will then have a merged dimension of YearMonth in both.
In your crosstab if you just use YearMonth you'll get just the five months. If you qualify it with its data provider name (in our case MONTHS), you'll see the full twelve months shown.
I hope that clears it up for your.
Regards,
Mark

Web Analysis : populate the same table with multiple data sources

Hi folks,
I would like to know if it is possible to populate a table with multiple data sources.
For instance, I'd like to create a table with 3 columns : Entity, Customer and AvgCostPerCust.
Entity and Customer come from one Essbase, AvgCostPerCust comes from HFM.
The objective is to get a calculated member which is Customer * AvgCostPerCust.
Any ideas ?
Once again, thanks for your help.

I would like to have the following output:
File 1 - Store 2 - Query A + Store 2 - Query B
File 2 - Store 4 - Query A + Store 4 - Query B
File 3 - Store 5 - Query A + Store 5 - Query B
the bursting level should be give at
File 1 - Store 2 - Query A + Store 2 - Query B
so the tag in the xml has to be split by common to these three rows.
since the data is coming from the diff query, and the data is not going to be under single tag.
you cannot burst it using concatenated data source.
But you can do it, using the datatemplate, and link the query and get the data for each file under a single query,
select distinct store_name from all-stores
select * from query1 where store name = :store_name === 1st query
select * from query2 where store name = :store_name === 2nd query
define the datastructure the way you wanted,
the xml will contain something like this
<stores>
<store> </store> - for store 2
<store> </store> - for store 3
<store> </store> - for store 4
<store> </store> - for store 5
<stores>
now you can burst it at store level.

BI+ Reporting With Multiple Data Sources

Hi -
We've been using BI+ Reports with multiple data sources on separate grids. We are wondering if there is a better way to ensure the user has their point of view bar in sync between the the data sources. In our case, both Data Sources are separate HFM applications with all the dimensions identical except the account which is defined on the report. We are not using Metadata Management.
I'm aware of the "Merge Equivalent Prompts" in the Preferences > Financial Reporting window, but this does not always ensure the users have the same point of view.
What practice are other companies using to make sure the user runs the reports accurately with both point of view bars pulling the same entity/year/period.
Thanks in advance.

Thanks for your answer, however my question - I know it looks quite messy - is not directly related to data templates, my problem is that at the moment I am using a stored procedure following - almost exactly - what another procedure does in oracle EBS to call a BI publisher report.
1. This procedure populates some temporary table with the xml data where the concurrent request picks it up and uses it to populate the BI publisher template.
2. However I can't go and specify the XML location in my data template as this is not an option for us (i.e. reading the xml from the temporary table), so I am looking for another way to populate the BI publisher template (Note: I can't as well include the SQL queries in my Data template).
Thanks ;)

Target Spry RowID on page with Multiple data sets from another page

Hi all,
I am trying to target a specific data item, on a page with
multiple data sets, from a link on another page. (I also have to
pass the link through Flash, but lets start with the simple
part...)
You can take a look at the site in progress here:
http://www.3andband.com/TestSite/iframeTest3.html
From the Home page I want to link to specific news or concert
items on the News page
I have been trying to get SpryURLUtils to do it but I can't
seem to get it working.
Any help would be greatly appreciated.
Thanks!
Ben

did u try if it even passes the row value?? with a simple
alert? alert(params.row)
Also maby u need to reorder the scripts to this;
<script src="../SpryAssets/SpryURLUtils.js"
type="text/javascript"></script>
<script src="../SpryAssets/xpath.js"
type="text/javascript"></script>
<script src="../SpryAssets/SpryData.js"
type="text/javascript"></script>
<script src="../SpryAssets/SpryCollapsiblePanel.js"
type="text/javascript"></script>
<script src="../SpryAssets/SpryEffects.js"
type="text/javascript"></script>
<script src="../SpryAssets/SpryAccordion.js"
type="text/javascript"></script>
and your js script
var params = Spry.Utils.getLocationParamsAsObject();
var dsConcerts = new
Spry.Data.XMLDataSet("includes/concerts.xml", "Concerts/concert");
dsConcerts.setColumnType("image", "image");
var dsNews = new Spry.Data.XMLDataSet("includes/news.xml",
"News/item");
//Set an observer so that when the data is loaded, we update
the current row to the url param value
dsNews.addObserver({ onPostLoad: function(ds, type) {
dsNews.setCurrentRow(params.row); }
function MM_effectBlind(targetElement, duration, from, to,
toggle)
Spry.Effect.DoBlind(targetElement, {duration: duration,
from: from, to: to, toggle: toggle});
So url params get loaded before the data

How can I create a details cube with millions records

Hello everyone,
I need now to create a cube for details data. But the problem is that the details data is very large. There are some millions records.
How can I design such cube in the essbase? Or can man create such cube in the essbase at all?
I need your suggests. Thank you very much!
Ming

hello Sandeep,
thank you for your reply.
Our situation is we have biee+essbase.
And the users want to see the details data. The data is too large.
The users want to get all data from excel (hyperion).
So there are many problem with the speed performance.
How can I design so that the performance is better?

MDX query performance on ASO cube with dynamic members

We have an ASO cube and we are using MDX queries to extract data from that cube. We are doing some performance testing on the MDX data extract.
Recently we made around 15-20 account dimension members dynamic in the ASO cube, and it is taking around 1 and a half hour for the query to run on an empty cube. Earlier the query was running in 1 minute on the empty cube when there were no dynamic members in the cube.
Am not clear why it takes so much time to extract data from MDX on an empty cube when there is nothing to extract. The performance has also degraded while extracting data on the cube with data in it.
Does dynamic members in the outline affect the MDX performance? Is there a way to exclude dynamic members from the MDX extract?
I appreciate any insights on this issue.

I guess it depends on what the formulas of those members in the dynamic hierarchy are doing.
As an extreme example, I can write a member formula to count every unique member combination in the cube and assign it to multiple members, regardless if I have any data in the database or not, that function is going to resolve itself when you query it and it is going to take a lot of time. You are probably somewhere in between there and a simple function that doesn't require any over head. So without seeing the MDX it is hard to say what about it might be causing an issue.
As far as excluding members there are various function in MDX to narrow down the set you are querying
Filter(), Contains(), Except(), Is(), Subset(), UDA(), etc.
Keep in mind you did not make members dynamic, you made a hierarchy dynamic, that is not the same thing and it does impact the way Essbase internally optimizes the database based on Stored vs dynamic hierarchies. So that alone can have an impact as well.

Help to fill BPS Cube with same data in a Cube with these conditions

Hi,
I need some help in implementing BPS in a small project. (Integrated Planning is not available).
An existing cube, Cube1 has: Year/month, Year, char1, char2, keyfig1, keyfig2
Keyfig1 is filled directly from R3 with actuals; keyfig2 (planned values) is filled manually filled with a monthly flat file load.
Now, there is a change in direction to fill keyfig2 through BPS features and bring in additional key figures all based on keyfig1.
Cube2 has been created only for the purpose of this BPS project. Cube2 was a copy of Cube1(with no data). For Cube1, I have created a Planningarea1 and PlanningLevel1; and for Cube2, Planningarea2 and PlanningLevel2 in BPS0.
How do I fill the BPS Cube2 with the same data as in BPS Cube1 with the following conditions:
keyfig1 : same as source value from R3 (not modifiable)
keyfig2 : modifiable by users only on the first and second of the month.
keyfig3 : keyfig1 * 1.1
keyfig4 : keyfig1 of previous Year/month
keyfig5 : same as source value from R3 (But modifiable)
keyfig6 : same as keyfig5 as of last day of 20th of the current month (not modifiable)
The goal is to create a multi planning area to join the two cubes. Hints all that will also be appreciated.
Thanks

Your thought of having a multi area is right.
Create a multi area and being the basic areas to which you have assigned cube 1 and cube 2 underneath the multi area.
UNder your planing package, create a function of type Formula and create a parameter set like this:
= * 1.1.
Just this one line will is enough.
TO get keyfig 4 as previous month's key fig; you need another fox. To do this, you need to have a BPS variable to et previous month and use this variable in the parameter set.
Your fox will be like this.
DATA CURRMONTN TYPE 0CALMONTH.
DATA PREMONTH TYPE 0CALMONTH.
{KEYFIG4, CURRMONTH} = {KEYFIG1, PREMONTH}.
To make users modify only on days 1 and 2, you need to define a dara slice.
