ER Time Dimension

HI
i have a problem of creating a ER diagram for Time Dimension which consist of tables are DAY , WEEK , MONTH , QUARTER , YEAR and the relationship between those tables
can someone help i need a full solution with attributes for each table

Do you mean you need help designing the actual model or help putting the model in SDDM? (If you need an example Time Dimension model this is not the right forum. You can search online for examples as there are many published.)

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:

check the source data and use the correct function eg TO_DATE(SRC.DATE, 'MM?DD/YYYY') use NVL if required.

Error while saving rpd (problen with time dimension)

Hi all.
I have business model that have no errors/warnings during "check consistency" procedure. But when I save rpd i get error:
-->The Physical table '***' which is part of a time dimension, is also used in the logical table 'XXX', which is not part of any time dimension.
Does someone know how to fix this?

Creating Time Dimension from date columns in fact tables.

I remember watching a demo from a BI Tool a couple years ago, wich I swear was OBIEE, and the presentator stated it was possible to create a Time Dimension in the admin tool, based on a date column in other table.
Can you guys tell me if there's such functionality in OBIEE?
If so, how could I achieve that?!
Thanks in advance!
Marcos

hi,
You are trying to make Fact table as Dim table ???
Fact table has some dim columns??
We can do this by making a fact table as dim table ,create a dim hierarchy on that table
Year level :Extract(year from fact_date_column)
Month and year level:CAST (Extract(month from fact_date_column) As CHAR(5) ) || CAST (Extract(yearfrom fact_date_column) As CHAR(5) )
Like this
But,be careful while doing this make sure that all joins and content levels are good
As per my knowledge this is not a good way,Experts can add some words lets see!!!!!! :-)
thanks,

Creating Time dimension in BW data model. - like seen in logical data model

Hello all,
I have been struggling with this thing and I am looking for some help from anyone on this forum.
We are trying to create a logical data model of our bw system. We are going live next month with Student module for universities. We have multiple Infocubes and DSO and since there is so much crossing over in between them most of the reporting is done on infosets.
One of the thing we were thinking; is it possible to create something like a common time dimension table for every infoprovider. Basically when we are providing the reports to the end user can we give them a drop down menu which gives a time frame for reporting rather than selecting.
Example: Like can we create something which looks in the drop down like current month data, last months data, three months ago, four months ago, five months ago, one year ago, two years ago. Can we make like these data slices in our cube and deliver it to the end user?
We have in our cube a few date infoobjects, like receipt date, decision date, cancellation date and like wise.
Please let me know if any one has done any similar thing, it will be very helpful.
Thank you so much in advance.

if you add your common time dimension to your data model, first identify for each infoprovider the time against which 'current month' and other frames should be applied and map them to your dimension.
just a question... are you not using time dimension in cubes ? ideally this should be your time dimension llinking all.
when you use time dimension which uses 'current month' , 'current year' , you will have to address their historisation as well. (because current month now will not be so current after 2 months).
so in data load procedure every day these values need to change (meaning drop and reload).
and routines to populate these values based on reporting date.

Hello wildmight.
I followed this tutorial:
http://www.rittmanmead.com/2007/04/30/obi-ee-time-dimensions-and-time-series-calculations/
Why should this layout not work?
Do you have a better idea?
When you say "it has to be one table" do you mean
that quartermonthday and year need to be ONE?
I just rememered that Oracle Hyperion Planning has to have
time and months seperated.
Hello mod100.
What do you mean hierachy over the time dimension?
Is it not obvious from the screen print that I have a hierachy
i.e. yeartotal - years and
quarters - months- days.
I read that by default the LEVELS are set to the lowerst. so thats fine. I set them by myself to the lowest as well but the ERROR is still the same.
no, I have not set the levels as in

How to generate a Time Dimension?

Hi,
How can you generate a Time Dimension for both fiscal and calendar year, complete with Month Ago, Quarter Ago, Year Ago, etc Attributes, and then populate with data? Is there any documentation on how to do this?

How do I include 'Time' in a time dimension?

I have a requirement where I need to classify the data in the warehouse based on date and time (example : between 10 am to 11 am, 3.00 pm to 6.00 pm like that).
The time dimension created by OWB contains only the date part and when I load the data I use the expression TO_NUMBER(TO_CHAR(input,'YYYYMMDD')) to populate the date.
But I would like to include the time also in the expression like 'YYYYMMDDHHMISS'. But unfortunately the OWB generated time dimension does not have data in this format.
How do I do that? Any pointers?
thanks in advance

You rather create 2 dimensions: Time and TimeOfDay. The first one will have all the date values with it characteristics. The second one will hold the all the possible HH24:MI:SS values with it's characteristics, for example which hour and which part of the day it is (Morning, Afternoon, Evening, Midnight or whether it's lunch time or not), depending on the requirements.
If you try to combine them both into 1 dimension you will get 86400 dimension records every day. Your dimension table will probably will become bigger than the fact tables.
