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?
Thanks

like this?

How to create a Time Dimension

Hi
This is regarding a new topic which i could not find the answer in this forum.
Actually i want to create a time dimension to populate my source data which is in date/time format.
can anyone please reply back reagrding how to create a time dimension in ODI???
regards
Gourisankar

Hi Gourisankar,
I am not aware of time dimension. But when i searched in metalink i got the below note. I am not sure whether it will help you or not but still a small contribution. :)
The note as follows,
To create new time dimensions, run the following SQL instructions :
* Example to generate a calendar between 1999-01-01 and 2007-12-31 one row per day
SELECT to_date('1999-01-01','YYYY-MM-DD')+rownum
FROM DUAL
CONNECT BY
ROWNUM<=to_date('2007-12-31','YYYY-MM-DD')-to_date('1999-01-01','YYYY- MM-DD');
* Example for generating a calendar random number
SELECT DBMS_RANDOM.VALUE
FROM DUAL
CONNECT BY ROWNUM<=1000000;
May be you can create a VIEW out of this query ,reverse it and use that as a source in your interface.
Try this and let me know.
Thanks,

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?.

OWB 10.2 - How are you handling time dimensions?

Hi all,
I am struggling with what should be a simple thing to do. I want to create a time dimension and then have many "roles" or aliases for the time dimensioin WITH UNIQUE COLUMN NAMES across all of the roles.
When the time dimensions are deployed to Discoverer, I want every one of them to have unique names and the column names within the time dimension have a unique prefix so that report users know which date column is from which table or dimension.
Here's what I've done and failed at:
1. Use the time dimension wizard - I can create any number of dimensions and corresponding tables BUT all of them have the same column names and I would have to manually change each and every one of them to get unique names (which may not even be possible with the wizard). Also, because I require ISO weeks, I can't really use the wizard at all.
2. Manually create a time dimension (that supports ISO weeks) and create multiple "roles" for it:
Thanks to a bug, I cannot exceed 4 roles without OWB crashing. Even with those 4 roles, when deployed to Discoverer, every attribute within the item folders has the same name. When I drag them to a report, there is no way to tell one from another. Is there some way I could do this without having to manually rename hundreds of columns?
3. I wrote an elaborate SQLPlus script to copy and prefix dimensions and tables from a base dimension and table. When I then import the Dimension to OWB, the metadata for business identifier and surrogate identifier is not there and any cubes using those dimensions do not work with these attributes missing. I can't find a way to cleanly reverse engineer these into OWB.
I have a cube with 12 dates - each of which should be a foreign key to a date dimension.
How can I have all of these be uniquely named with uniquely named columns?
How can I make it easy for my reporting users to select dates onto their reports?
I hope I am missing an obvious solution, because so far, I cannot see where Oracle Warehouse Builder supports such a basic data warehousing concept.

Well, since I'm the only one obsessed with time dimensions I guess, here is my ugly workaround:
1. I create a base time dimension in OWB which I named 'ATLAS_TIME_DIM'
2. I run the OMB script below which clones the dimension and table and renames the columns and attributes with a user supplied suffix. The end result is I get a full copy of the time dimension metadata with uniquely named columns.
You then have to deploy the objects, and with SQLPlus, ensure that the table gets its data copied from your original table. Hope it helps someone until we have better Time dimension support from OWB.

How to generate current time in the format yyyy-mm-ddThh:mm:ssZ in the xslt

Hello,
i am tring to generate current time in the format yyyy-mm-ddThh:mm:ssZ in my xlst file.
the following info are necessary,
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:java="http://xml.apache.org/xslt/java" exclude-result-prefixes="java"
version="1.0">
<xsl:attribute name="generationDate"><xsl:value-of select="java:format(java:java.text.SimpleDateFormat.new('yyyy-mm-dd hh:mm:ss'), java:java.util.Date.new())"/></xsl:attribute>
but java SimpleDateFormat doesnt support yyyy-mm-ddThh:mm:ssZ.
thanks in advance.

Hi wwuest,
I use the following code to generate such a date format :
          try {
               SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
               Date date = sdf.parse(strDate);
               sdf.applyPattern("yyyy-MM-dd'T'hh:mm:ss");
               strDate = sdf.format(date);
          } // catching the parse exceptionMaybe you could try this method and see if it pass through xsl with :
new SimpleDateFormat("yyyy-MM-dd").applyPattern("yyyy-MM-dd'T'hh:mm:ss'Z'")Bye

How can I modify Time dimension to create a Top member above year members ?

Hi experts,
I would like to modify Time dimension to add a Top member above year members.
I already did a test:
I added a member in Time dimension which is the parent of all year members. I granted it these property values:
- ID = TOTAL
- EVDESCRIPTION = Total
- LEVEL = TOTAL
- HLEVEL = 1 (and I added 1 to all the other members)
- TIMEID = 10000001
All other properties were left blank for this member.
I processed the dimension. It went well. But when I tried an evdre in BPC excel it failed.
Any idea of something missing ?
I am working on SAP BPC MS 7 SP4
Thanks for your help
Ludovic

Hi Petar,
Thanks for your answer. No doubt that we could solve the issue using on of the way you suggested.
However, even though I had the evdre issue right after applying time dimension modifications, it occurs that the evdre issue was not due to time dimension modifications. I tested it better and I can tell that using "total" as a level works.
Best regards,
Ludovic

How to load time dimension informatica...

Hi, im new to datawarehouse... Can anybody tell me,how to load time dimension informatica...
Thanks and Regards,
jagadish.

Do you mean Informatica, the ETL tool? If you do then I would post your question on the Informatica website as we typically use Oracle Warehouse Builder and Analytic Workspace Manager here at Oracle.
If you want to know hoe to generate a time dimension table, then I would recommend using the Time Dimension Wizard in Warehouse Builder as this will automatically create the target dimension table and populate all the required levels with the correct data values. There is more information on the OWB OTN Home Page

How to Link two Facts with Different Time Granularity (Year, Quarter) to a Single Time Dimension

Hello All,
I have the below scenario where i have Two Facts Fact Quarterly and Fact Yearly but one Time Dimension which has Quarter grain.
So my question is how do i Establish relationship from Fact Yearly to Time Dimension??
Ex:

Hi naveej,
According to your description, you want to know how to build the relationship with time dimension and fact tables. Right?
Based on your screenshot, it's better to have only one fact table for sales and build the relationship with time dimension. To determine quarterly or yearly data only depends on how you slice the time dimension. However, I notice that the Revenue for year
is different from the aggregated Profit for quarters. If the Revenue and Profit are different measure, you need to have two fact tables. And you should build the relationship (Regular) between TimeDim and FactYearly on YYYY attribute.

How to include a time condition in a Vi?

Hi,
I need to run an event for one hour and after this time interval has elapsed, I need to stop this event (let�s call it event A) and go for event B. I have been trying to work with the Elapsed Time (LabView 7.0) sub-vi with no success. That sub-vi sounded perfect as I could even work with a boolean condition to trigger event B. Basically what I would like to know is how to generate a time condition in which I can input the time and after that time has elapsed I can generate an action to pass to another event? Would it be an simple way of doing so?
Thanks for the help.
Adriana

I may be missing something here, but I think your problem is not the Elapsed Time VI, but the way your events are triggered/controled or chained. Or may be you just forgot to wrap the Elapsed time vi into a loop ?
See the attached example...
The "Run event A" sub.vi is intended to trigger event A. Something like commuting a switch or launching a dynamically loaded vi. It should not wait until event A finishes (of course...).
There are many possibilities... and I'm sure that you will get other solutions.
Keep wiring !

Modifying Existing Time Dimension

Hi All,
Presently I have a Time Dimension and a Fact table which has a FK to this Dimension. The Time Dim has a level upto hourly values.
Now it's in production and I need to change the Time Dim to take on minutes 'cause some reports need minutes.
1. So what is the best way to go about this?
2. Is it better just to add another extra field which has the required date, in the fact table?
3. How can the existing data be easily ported to the new Time Dim(if it has a minute-level)?
Thanks,
Justin.

I am wondering how you implemented the time dimension which only has a level up to hourly values. Do you mean the time dimension only has 24+1 = 25 rows? Usually the time dimension is separate from the date dimension and its lowest level values are minutes or seconds, depending on the business requirements. Therefore the time dimension should have 24X60 + 1 or 24X60X60 +1 rows.
The solution is depended on what you want.
My suggestion is as the follows:
1.     Create a new time dimension with the desired lowest level values (minutes or seconds).
2.     Create or modify the foreign key of the fact table to point the new created time dimension.
3.     Modify the ETL mappings.
4.     Option 1: If you want the new functionality available for the existing rows in the fact, you have to reload the fact no matter which approach you use.
Option 2: If you only want the new functionality available for the subsequent refresh load, you can modify the foreign-key values pointing to the old time dimension to the new time dimension, using the rule XX --> XX:00 or XX --> XX:00:00 (where XX is the hour number in the old dimension). In the subsequent refresh load, map the foreign-key values to the actual time.
Maybe other else can provide better solutions. IF so, please let me know.
Good luck!

Modelling Time Dimension with Fact Table containing Start Date and End Date

Hi Gurus,
I have a time dimension with Year till Date. I have a fact table which consists of Start Date, End Date, Person ID, Department ID.
How do i design Time dimension with fact table the below scenario
In the dashboard i have start Month and End month as prompts.
In the report i need to display Count(Person ID) > Start Date and < End Date along the trend.
For instance, i have selected Jan-2009 as start date and Apr-2009 as End Date, then i need to display Count(Person ID) of Jan-2009, Feb2009, Mar-2009 andApr-2009.
I Can not connect Time dimension with only Start Date or only with End Date to get the trend along the months.
Please advice on the issue which i am having.

Hi,
Thanks for the response, Infact i tried using Complex join in physical layer. I have considered Time table joined with Fact table, and used >= and took and alias of the Time table and joined fact table using <=. When coming to BMM, i am not knowing how do i design this as if i merge the both the time dimensiona and its alias into single table, values will not be correct and if i make them as seperate columns. i can not show the trend as both are different columns.
Can you please let know where i am going wrong.
Thanks

Cannot recreate mapping to populate MOLAP time dimension

I am using OWB10gR2 to create a time dimension having MOLAP as storage type and two hierarchies (year and week).
I used the wizard to create a time dimension having the standard year hierarchy. The wizard does not allow to generate the time dimension with both hierarchies (why?). That's why I had to manually add the week hierarchy with the object editor in a second step. The next step would be to recreate the mapping to populate the time dimension, but I got the following error message:
"There is no sequence attached to the dimension. Please add a sequence in the attribute tab."
I tried the same thing with ROLAP as storage types: for ROLAP I can recreate the mapping.
Does anybody have a solution for that problem?
Many thanks in advance!!

I further explored the Time dimension wizard and for standard if i select year,month and day .... the autogenerated mapping generates a validation error... Anyways i am using oracle11gr2 any ideas why this is happening ??

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.

How to know on which time dimension level we are ?

Hello,
I would like to know is there a variable or a mean to know dynamically on which time dimension level we are in order to use that in a CASE WHEN clause ?
By using a sort of aggregation tables in which one of the column contains the name of the level, I could know on which level I am but I can't use that for drill down. What I mean :
Tab1 :
'Year' as typelevel, year
Tab2 :
'Month' as typelevel, year, month
In BMM, I have made one logical table with as Source tab1 and tab2 and as columns typelevel, year and month.
tab1 has in content column the year level
tab2 has in content column the month level.
So when in Answers I retrieve
typelevel, year
the result is : 'Year', 2008
and when I request : typelevel, year, month
the result is : 'Month', 2008, 1
But if I want to drill from year to month in order to have :
'Year', 2008
and then after drill
'Month', 2008, 1
it is impossible as a filter on typelevel='Year' is added on the month level, so it retrieves 0 columns.
If someone has an idea on how to do that it would be very great.
Thanks in advance for your help.

Hi Supriya,
OOTB I think you can use SharePoint designer, but I would suggest custom code to iterate to all pages, and get the lists that are associated with these pages.
http://stackoverflow.com/questions/633633/sharepoint-how-can-i-find-all-the-pages-that-host-a-particular-web-part
another one would be if those lists were never used and you can check for list with empty data.
I would use Get-SPLists to get all of the lists to check for zero items.

1. I choose Dimensions -> New -> Using Time Wizard
2. Set Name as "Time"
3. On the next screen I choose ROLAP: Relational Storage
4. On the next screen set Start year: 2003, Number of years: 3
5. On the next screen choose all levels of the Normal Hierarchy
On the 6-th step Wizard complete 60% of job and hang up doing nothing (buttons "Cancel" and "Help" is active).
chapter "Create REL_TIME Dimension Using the TIME Dimension Wizard", step 1-6 of tutorial =(
