Time Dimension Average @ Lev2

Hi,I'm having a problem with calculating the TB Average at Lev2 of my Time Dim.Time Dim: Week (Lev0), Month (Lev1), Year (Lev2), Time (Lev3)Week to Month OkMonth to Year Not OkMonth to Year calculates the average using the Month TB Average (average of average).I've tried using a Member calc [@AVG (SKIPBOTH,@LEVMBRS ("Time",0))] for the Year Member so it calculates the average based on the Lev0 figures.Don't really want to have a separate the Years into a different dimension.Thanks in advance.Mark

Thanks for your reply. Did you use the dimension wizard of OWB to create pure relational dimensions (Not owb/oracle dimensional structures) ?
How did you work out week, financial years pieces upon using this OWB dimension wizard?
Thanks for your help.

Time Dimension in Dynamic Reporting

When creating a report that compares a current period (for example 2015.FEB) to the same period in the prior year (2014.FEB), what is the best logic to use in a report? Do I use a local member formula to perform this? I am willing to build in a property within the Time Dimension table if necessary.
I will probably have the same need to compare current period (2015.FEB) to prior period (2015.JAN) in the same report.
The average user isn't very knowledgeable working with reports besides picking from the context drop down so it needs to be where they pick the current month (2015.FEB) and the report does the rest.
***It should also be noted that we recently switched from a calendar year to fiscal year so it will not work to reference for example Period 2 in each year since 2014.FEB is period 2 and 2015.FEB is period 11 in each year respectively.
Thanks for the help.

Shrikant,
See attached 4 screenshots of all of the properties that I have in the time dimension.
We only have one hierarchy for time. As you can see its a little complex going from a calendar year reporting structure to a fiscal reporting structure. 2014 was a "short" year because of the change.
Thanks in advance,
Steve

Non-additive time dimension

Hi, I have an issue modelling the time dimension for one of our facts (employee counts). The problem is this - when a user says "I want to see the count of employees for a given time period" - what they mean is that they want to see the count of employees as of the last day in that time period. i.e. "June employee counts" means employee counts as of 6/30, "Year 2000" employee counts means as of 12/31/2000.
This is very similar to modelling a "ending balance" inventory type problem in OBIEE.
I've solved this (poorly) in OBIEE by changing the aggregation to use "LAST" for the time dimension and "count(distinct(emplid))" for everything else. This works....but....the performance is horrible. If I ask for employee counts for year 2000, it appears to bring down employee counts for all 365 days in the year, then sorting them by date, then throwing away all except the last date. In other words, it brings back 364 days worth of records and then throws them away. This makes the query perform absolutely terrible. A 2 or 3 second query ends up running for minutes.
Does anyone have a different way to solve this issue?
Thanks,
Scott

Hi Christian - agree completely, I just wish OBIEE were smart enough to do the "last" bit on the 2000 row time dimension instead of the mutli-million rows fact table...
I've thought about trying to materialize the measures, but I have a hidden "twist" on my data. In our fact table, I do NOT write a record for each day for each employee. Instead, I only write a record when something on the employee fact changes. So instead of having a hard "date" column, I instead have a "start date" and "end date", and then need to join to the reporting date dimension using a BETWEEN. I do this because most records stay unchanged for long periods of time, so instead of 365 records per employee per year, I average under 3 records per employee per year.
I may give the multiple fact LTS a try, but truthfully I'm a big believer in simplicity (mainly because I'm lazy....) so was trying to find something easier.
And honestly, I'd use a cube if I could, I'm a (very) old Express wiennie.
Thanks,
Scott

Universe Design Question - Time dimension

Hi,
Please help me with universe design question here.
I have to make line graph
Y- axis time dimension hh24:mi:ss
y - axis Date dimension YYYYMM
The data is like this
progname end_date
abcd 2011/01/23 13:01:20
abcd 2011/01/24 13:30:20
abcd 2011/01/25 13:34:20
abcd 2011/01/23 13:34:20
abcd 2011/01/25 13:45:20
abcd 2011/01/2614:34:20
I need to take time portion of each month and take average of it and that is printed on graph.
I just wonder how I get average of time. The tool seems like can not get average of time as this is not a number.
Then I converted time portion into seconds and did the average but my requirement is to show time on line graph not in seconds.
Please give some idea.
Thanks.

Hi Afzal,
I know how to segregate the date part and the time part. I just wonder how I get average of time. The tool seems like can not get average of time as this is not a number.
Then I converted time portion into seconds and did the average but my requirement is to show time on line graph not in seconds.
Please give some idea.

Aggregation mode along one dimension (product) different than along the time dimension

Dear All,
In IBP S&OP, Is it possible that the aggregation mode along one dimension (product) could be different than along the time dimension?
For a demo, a customer has an input at the product family level (vehicle production) which we just “copy” for disaggregation purposes, to the product level (parts), see attached. So for aggregation we used average.
However, time-wise, we need to sum it up.
Thanks for your insight and help.
Kind Regards,
Omar

Hi Omar,
Yes it is possible.
1. Create a new planning level (say PERPRODCUST1) which will be a copy of PERPRODCUST (you base planning level).
2. In the PER section of PERPRODCUST1, do NOT mark any period attribute as root. In other words, the roots for this PL will only be PRDID and CUSTID.
3. Now your KF calculations will be:
VEHICLEPRODUCTION@PERPRODCUST1 = SUM(VEHICLEPRODUCTION@PERPRODCUST)
VEHICLEPRODUCTION@REQUEST = AVG(VEHICLEPRODUCTION@PERPRODCUST1)
Since your KF is editable, it is worth mentioning that, following the above steps has trade-offs. Since your KF is editable, you will have issues with disaggregation when you enter the values at an aggregated level of both time and other attributes. My recommendation (for your configuration) is that this will work fine as long you enter the values at the root level of you time attribute.
Hope this helps,
Chendur

Populating the Time Dimension

Ok, the Oracle Enterprise Manager was kind enough to automatically create the often used Time dimension for me. It even created the associated look up table for me.
Question:
Is there a facility/function/feature that populates the weeks - month - year levels in this new lookup table or do I have to do it "by hand"?
Thanks for your time.

How to build the time dimension in Essbase with Fiscal Year (July thru Jun)

Hi,
In a recent project i have a situation where i need the time dimension to have some thing like this Fiscal Year (July - June) using BSO need to achieve DTS (YTD and QTD) functionality also.
And also my reports should also be able to drill through and needs comparison years(Prev Year Vs Current Year), months(Prev Year Vs Current Year) and Qtrs(Prev Year Vs Current Year).
How can i achieve this using BSO?.

Advice needed: join fact to time dimension with between clause

Hi All,
I've got 1 dimension and two fact tables. The 1 dimension could serve as a time dimension.(not specifically marked as this is a time dimension)
My Tables look like this (simplified)
Dim1:
date_pk (unique identifier)
date
month
year
fact1:
iid_date (foreign key to date_pk)
fact1_amount
Fact2:
begin_date
end_date
fact2_amount
In the physical layer i have a complex join between fact 1 and dim1 (date_pk = idd_date) and a complex join between fact2 and dim1 (dim1.date between fact2.begin_date and fact2.end_date and dim1.date <= CURRENT_DATE). In the business model i have complex joins between fact1 and dim1 and a complex join between fact2 and dim1 without further specification.
What I would like to achieve in Answers is that I select a Year and a Month from dim1 and add fact1_amount and fact2_amount to the same report and that the report shows both amounts. I would like some advice on how to set this up. Further more how to add a drill from year to month to date and what should I do when I'm willing to add more facts joined to the same Dim1
Any Advice is greatly appreciated
Gilles

Hello MMA1709,
You're right, this setup works!
But...
When you add an hierarchy and mark it as a time dimension it doesn't work anymore. It gives the following error in the consistency checker:
[38086] Physical table Dim1 in the time dimenison table source Dim1 is part of a complex join condition
And that means you cannot use any timebased calculations (AGO and TODATE). When I just create an hierarchy and do not mark it as a time dimension the hierarchy works well.
Any suggestions?

Slicer Time Dimension Issue with Cube Functions

Hi,
Hoping someone can help me figure out right approach here.
Summary:
Using Excel 2013 connected to a SSAS cube as data source, and cube functions with slicers to create a dashboard.
Have following time dimension slicers; Fiscal Year, Fiscal Quarter, Fiscal Month, Fiscal Week & Date, that are used to slice data based on user selection, along
with a sales measure.
Below is example of Slicer name and CubeMember function for each:
Slicer_Fiscal_Year:
=CUBEMEMBER("Cube","[Date].[Fiscal Year].&[2015]")
Slicer_Fiscal_Quarter:
=CUBEMEMBER("Cube","[Date].[Fiscal Quarter].[All]")
Slicer_Fiscal_Month:
=CUBEMEMBER("Cube","[Date].[Fiscal Month].&[201408]")
Slicer_Fiscal_Week:
=CUBEMEMBER("Cube","[Date].[Fiscal Week].&[201509]")
Slicer_Date:
=CUBEMEMBER("Cube","[Date].[Date].[All]")
Problem:
What I am trying to do is to build a table with cube functions that takes the lowest grain of the slicer time dimension selected, shows the current member, plus
the prior 7 so I can have an 8 period trending view table that I will build a chart from. In the above example that would mean that it would look at Slicer_Fiscal_Week since that is lowest grain that has an attribute other than All, and then show me the prior
7 periods. In this case 201509 means Week 9, so I would want to show in table Week 9 back to Week 2. But if Slicer_Fiscal_Week was set to All, along with Slicer_Date, then Fiscal Month would be lowest grain, so I would want to show Fiscal Months from August
(201408) back to January 2014. I know how to use CubeRankedMember to pull the value from what is selected in the slicer, the problem is figuring out how to pass the lowest grain time dimension so that I can use lag or some other MDX function to get the previous
periods.
Any help on this would be greatly appreciated.

Fiscal Year Time Dimension - Month Time Span

I have a need to create a fiscal year time dimension and I created using Time Wizard in OWB. When I was developing BI Reports, I found some inconsistencies in Time dimension as it was showing figures in all the months of my first quarter of new financial year that Apr 2009 – Mar 2010. On close inspection of Time Dimension table I found that fiscal_month_time_span value varies from 35 to 28 to 29 for different months. i.e. it’s not matching with corresponding Calendar month. This means I am unable to plot data correctly using fiscal year dimension.
Maybe this is how it works in Oracle, but this does not solve my problem. Could anyone give me some solution for this ? My Fiscal year is from ‘1- Apr – 09’ to ’31-Mar-10’. In my reports I would like to see transactions for April month when I use month attribute of time dimension like it happens in Calendar time dimension.

May be someone from

Multiple Fiscal Calendars Displayed in Subject Area Time Dimension

Hi all,
Thanks for taking the time to review my post.
Environment
Oracle BI Applications 7.9.6 Financial Analytics
Oracle E-Business Suite 11.5.10
Query
The Time dimension on my Subject Areas (Financial Analytics) are showing more period data than I expected.
I have configured one Enterprise Calendar (WPG_Calendar) that I set in the DAC parameters - $$GBL_CALENDAR_ID (WPG_Calendar~Month) and $$GBL_DATASOURCE_NUM_ID (4). The warehouse Enterprise Calendar table W_ENT_PERIOD_D is populating with the periods as configured in EBS for that calendar(Jan-09, Feb-0, Mar-09, etc). I noticed that the Multiple Fiscal W_MCAL_PERIOD_D table is also been populated with the Enterprise Calendar data PLUS, the Seeded EBS calendar (JEBE_MONTH_VAT) and a generated Calendar that appears to be a 5-4-5-4 Calendar (Jan-01-09, Jan-02-09, Jan-03-09, etc). The trouble is these W_MCAL_PERIOD_D periods and dates are all coming through in my Time dimensions and make it confusing for the Answers Users when choosing a Time dimension.
Also, for columns W_CURRENT_MCAL_PERIOD_CODE, W_CURRENT_MCAL_QTR_CODE, W_CURRENT_MCAL_YEAR_CODE there are rows with Current, Previous and Next populated that span these different periods as you would expect, but I'm concerned these return multiple rows for Filters Current Fiscal Quater, Current Fiscal Year.
Funnily enough, W_CURRENT_MCAL_MONTH_CODE has nothing populated (NULLs for all rows).
Your comments are most welcome.
Kind Regards,
Gary.

The filtering of the calendar can be done directly on the logical layer.
for the logical dimension "Dim - Date Fiscal Calendar", Logical Table Source "Dim_W_MCAL_PERIOD_D_Fiscal_Period"
set the content as :
"Oracle Data Warehouse".Catalog.dbo.Dim_W_MCAL_PERIOD_D_Fiscal_Period.MCAL_CAL_WID = VALUEOF("MY_MCAL_WID")
and setup the repository variable MY_MCAL_WID to match with your calendar wid.
If your calendar depends on any context then you can use session variable instead of repository variable

Date and Time dimensions

After reading the following article, I have decided to use SSAS dimension wizard for generating our Date dimension, which creates a DATETIME PK.
http://www.made2mentor.com/2011/05/date-vs-integer-datatypes-as-primary-key-for-date-dimensions/
I have also created a separate Time dimension as granularity of an hour is required.
The Time dimension is very simple and only contains a surrogate key (INTEGER) and actual time in hours (VARCHAR).
DimTime(TimeKey, TimeInHours)
Our Fact table will now have a link to both the Date and Time dimension using the PK's.
Our analysis is required by hour, day, week, month and year.
My query is; Will this current structure cause any problems when creating MDX scripts to analyse our data (i.e. drilldown and rollup queries) Hour - Day - Week - Month - Year

Hi Darren,
According to your description, there a day and hour granularity in your fact table, so you want to a hierarchy like Hour - Day - Week - Month - Year, right?
In your scenario, you created a time table that only contains a surrogate key (INTEGER) and actual time in hours (VARCHAR). We cannot create a Hour - Day - Week - Month - Year hierarchy without ant relationship between date table and time table. As per my understanding,
you need create a foreigner key in time table, and join those table in the data source view, then you can create such a hierarchy. Here are some links about create time dimension, please see:
