• Time Dimension table

  Hello

  I have a requirement where I need to calculate the value of average purchase order based on the month. The problem I have here is that the custom time Dimension table that I have in my RPD has dates only until 2011 and not beyond. I downloaded this table via BI tutorials oracle schema EXAMPLE.

  I've looked everywhere on the internet for a time dimension table, but I'm unable to find it. Can someone please help me find a way to insert the time dimension table?

  Thank you

  Hi Anthony,.

  You can change the SQL code to insert new rows into your table.

  Example:

  INSERT INTO your_table (your_field)

  SELECT TO_DATE('31/12/2010','DD/MM/YYYY') + NUMTODSINTERVAL (n, 'day') AS Full_Date

  FROM (SELECT level n FROM dual connect by level)<>

  The foregoing will insert lines starting at 01/01/2011 and until the 01/01/2011 + 4000 days (over 10 years).

  Of course, you must extend the code to calculate all the fields in your time dimension.

• error in creating time dimension OLAP in ORDM

  HI Experts

  I am trying to update the data in olap time dimension that is based in ORDM of MV and I get the error message "path of aggregation for the hierarchies of a dimension 'TIME' is incompatible," Please suggest what is at stake / soln.

  Thank you

  Prateek

  Hi David,

  Please check your hierarchies for consistency.  Because it seems that the TIME dimension is selected for the updating of the MV, the hierarchies must be consistent star.

  This means that the hierarchies must be consistent with each other in regard to members and stars according to the subject at a level.

  Compatible with each other.

  "If a dimension member appears in several hierarchies, then his descendants playing to the level of detail are exactly the same in each hierarchy." For example, if Quarter_1 consists of January, February and March at the level of detail in the Calendar hierarchy, Quarter_1 cannot be July, August and September in the Fiscal hierarchy.

  However, the members of a hierarchy can have different parents in other hierarchies. For example, these customer hierarchies are compatible if the 'Total' Member all members at the SHIP_TO level in deliveries and market Segment. »

  -helps AWM on the Details of the implementation of the Panel properties of Dimension tab

  Consistent stars with each other = in addition to being consistent with each other, such as defined above,

  "If a parent has children at the same level in multiple hierarchies, these children must be identical. For example, suppose an a H1 and H2 hierarchies dimension and level L3 appears in both entities. If X parent has children, C1, C2 and C3 at the L3 level in hierarchy H1, X also children a C1, C2 and C3 to the L3 level in hierarchy H2.

  Following customer hierarchies are consistent star only if two hierarchies, REGION has the same members (for example, Americas, Europe, Pacific), rolling among the SHIP_TO members themselves.

  Hierarchy of shipments:

  TOTAL

  REGION

  WAREHOUSE

  SHIP_TO

  Hierarchy of the country:

  TOTAL

  REGION

  SUBREGION

  DEPARTMENT / PROVINCE

• Time Dimension type to different values in the attributes - Bug or feature?

  Not sure if this is a bug or a feature.
  
  But if there is a time dimension hierarchies. You have the option of specifying different values for member attributes in different hierarchies.
  
  For example.
  
  A hierarchy has MIN_ID for its members and uses MIN_END_DATE for its end_date
  
  Hierarchy B has MIN_ID for its members and uses SESS_END_DATE for its end_date
  
  According to this message and a comment by David Greenfield:
  
  Gender issue when several mappings for different hierarchies
  
  "You try to map the same attribute, SORT, on different columns in two hierarchies? In other words, what do you expect the same Member to have different values for the attribute in the two different hierarchies? If so, then this is a problem because a member must have the same value for the attribute independently of the hierarchy. »
  
  Unlike a dimension of the user, a time dimension seems to allow this and it seems to work as expected. Behavior in this case is the difference between a user and the time dimension?

  Your description of the structure of the dimension is very clear, but I have a question about system requirements. When you say you want to the time running from 17:00 to 16:59, do you mean that the calculation must spand day? for example "5:00 PM: Jan 1, 2012" to "4:59 PM: 2 Jan 2012".» If so, then this you is impossible by making a loop only the dimension of time-seconds. Or do you really mean it must wrap around the same day. for example "5:00 PM: Jan 1, 2012" at "11:59 PM: 1 Jan 2012", then again to "00:00 AM: 1 Jan 2012" to "4:59 PM: 1 Jan 2012"?»»»

  If you want the calculation for the period of days, then I think you need to spend TIME on the DATE dimension level. You can leave some MINUTES in the second dimension, which can be a dimension of standard user. You must then two levels of the DAY (with different members) in the date dimension - each with a different set of the child. You can assign the TIME_SPAN to the TIME level 1.

• Best practices for the Time Dimension

  I'm a new contour design. I need to set up a time for daily dimension, perpetually. In the past I would set up a member years i.e. 2010, 2011, 2012... and a second dimension with the days i.e. Jan 01, 02 Jan.
  
  Is there a better way than that? I would like if possible do so in only one dimension.

  Have you looked at the Date-Time dimension? It's ASO-only, but has a ton of features:
  http://download.Oracle.com/docs/CD/E12825_01/EPM.111/eashelp/frameset.htm?sel_cal_hier.htm

  He put everything in a single dimension, btw. I've seen similar dimensions in cubes BSO stored in sparse form. Shudder.

• S.o. of time Dimension

  Hi all
  
  In the project current works unlike the day regular 00:00 to 24:00 that the day of the transaction is divided into two shifts; Maj r: 06:00 to 21:00 SHIFT B: 21:00-06:00 the next morning.
  
  The customer wants to run reports on transactions happening in one day that spread over two shifts and would then like to generate MIN, MAX, AVG time. My time dimension currently has the following columns:
  
  Timestamp
  Year
  Month
  Week
  Day
  
  
  You don't know how to accommodate the transaction date that is a "single day" that falls within "two days".
  
  Any help is greatly appreciated.
  
  Concerning
  B

  Hi B,

  I hope that you do not use W_DAY_D / W_MCAL_DAY_D the granularity that is Date and time. You said that you have Timestamp in your time Dimension, so I'll give you the solution accordingly.

  Add two columns in your time Dimension. A Transaction shift and others for the day of the Transaction. Your ETL must fill these columns, accordingly as you mentioned logic. If you have a similar logic for Transaction week / month / year, you add the columns accordingly.

  Now, once you expose these columns in the presentation layer and the users query your metrics made against trading day, you will get your desired results. Please note that your should be attached to the dimension of time at the level of the timestamp and not date.

  Please let me know if it solves your problem.

  Thank you

• Time dimensions in double

  Hi all
  
  I think I have a simple requirement but I don't how it works:
  
  I have some dimensions and a fact table. In my table of facts, I have 2 foreign key on my dimension of time.
  When I import my tables and check the consistency, I get errors: "in double foreign key. Delete"(don't remember complete sentence)
  This is the first point that I do not understand. Why can I have not more than 1 foreign key?
  
  The second point is to know how to have 2 time dimensions. In the MDB, I duplicate my time dimension. But which to choose? I tested with a foreign key and complex join (and foreign keys 2 or 1 in Physics) and I still have the same result (bad).
  
  So can someone explain to me how configure both physical than MDB joins use a dimension greater than 1 hour (without creating a new physical dimension of course)
  
  Thank you

  Hello

  Create table aliases (as they play different roles) for the dimension of time in the physical layer and combining your done using physical joints.

  After importing to the physical layer, if duplicate keys exist, delete the duplicate keys.

  In this scenario, two keys will be exist on the fact for the time dimension, remove those and create the joins between aliases.

  Thank you

• Hour/Min column in the Time Dimension

  Please can someone help me with the script to fill in the time Dimension Table that contains a column of hours/min. Here's my Time_D structure:
  
  Year
  Quarter
  Month
  Name of the month
  Week
  Day
  Hour
  Min
  
  Also is it a good practice to have the hour/Min column in the time Dimension?
  
  
  Thanks in advance.
  Concerning
  B

  B,
  Sorry if I confused things a bit...
  I wanted to say in the MDB layer, you can model a dimension table (time) with the path complete drill (year-> quarter-> month-> day-> hour-> Min)
  This a logical table would have two sources of logical table to map required fields of your two tables of phyiscal (Date_Dim and Time_Dim)
  You must define the levels of content accordingly for each logical table source, so the user in responses can perfectly break of the year all the way up to Min, their sound a single dimension, actually its two tables and the BI server switches according to the levels of content in the LTS.

  Sorted?
  Let us know if you get the probs.

• Add the quarter to the time dimension

  Hello
  
  We have created a time dimension using the owb wizzard, but did not include the quarter level. Is it possible to add it to the dimension later without deleting a re-creation of the entire dimension?
  A new time dimension would probably be corrupt all the cubes (data and metadata), so I would avoid that.
  Any ideas?
  
  See you soon,.
  
  Knut

  Hi Knut

  Yep, should be possible.

  Change the dimension and select the quarter level in the levels Panel, and then click quarter in hierarchies pane to add it to the hierarchy. You can then delete the link and autobind on details for the physical links to the underlying table. On the hierarchies pane, there is a button "Create map" that will regenerate the mapping to load the time dimension.

• 1 h period and the time dimension

  Hi all
  
  1. I'm new to OWB and I was wondering is it possible to force the default time dimension (done using Wizard) to have some 'small' level then a day (say, 1 h)?
  If this is not the case, have you tried to manually update the dimension and mapping?
  Or it is better to leave default dimension and start with my own time dim?
  
  2. What is the difference between the dimension created as the dimension "time" and with a similar but defined content as typicall dim? (issues / analysis performance)?
  
  Thanks in advance.
  See you soon,.
  B

  Hello

  OWB can create dimensions date to the level of the day.
  You can use this dimension as a source of a map of your own to create a time dimension to the level of the time (enclose it with values of 1-24).

  Have you considered using a date on the day level dimension and a second dimesion of time containing only 1-24 hours?

  With the help of the wizard makes living easier, but there is no advantage in terms of performance in relation to a normal size. Be sure to add all the clues you need.

  Kind regards
  Carsten.

• Question about time Dimension Type Format

  Hello, I've created a repository and I see that my time dimension has a strange format type. When I'm in answers page and click on the year and click "Show results", I see all my years of my database, but in this format:
  2.006
  2007
  2,008
  ...
  
  And I want to see:
  2006
  2007
  2008 (no period separator)
  
  And also if I'm going to filter my highlights of the year and I click on allchoices... it shows not my years as:
  2006.00
  2007.00
  2008.00
  
  Everyone knows about it?
  
  Thank you very much

  First check the data type you specified for the year column in the physical layer of the repository. Is this other thing as integers?

• Time dimension wizard is not apear

  I'm just starting with OWB and have a few questions. I use OWB version 10.1.0.4.0.
  
  
  1. when I try to create a time dimension (right-click on the dimension) only 'create the dimension' will apear and not an opportunity to choose a wizard. What I am doing wrong?
  
  2. is it possible to display the content (data) in a table directly from the mapping Editor?
  
  THX in advance,
  
  Arjan

  Hi Arjan

  If you really must use OWB 10.1... This is true of OWB 10.1. OWB 10.1 has a standard dimension wizard, and there was a table function, condition to generate data, the card had to be built manually. See the 10.1 user guide, Chapter 22 - OLAP allowing with OWB. This article describes a time dimension prepackaged, that you can use if necessary.

  The version 10.2 OWB introduces wizards of dimension/time with on the support of the box and is wizard driven. Version 10.2 OWB has much richer support OLAP, OWB 10.1, it was made by a best practice/bridge technique.

• How to create the time dimension?

  Hi friends...
  I'm working on OBIEE since the last 2 months.
  I created a few reports; I don't have the time dimensions in the layer of MDB.
  
  Now, I need to give a few zoom feature in my reports. Almost all of the reports have the time factor.
  As year, month, and day. can I still create the time dimension based on the exercise.
  (1) what is - that I think give the zoom feature in the reports.
  (2) can we have multiple time dimensions in the MDB layer?
  
  
  Thank you very much in advance.

  Toony,

  You can create a time dimension based on the fiscal year, and you can have many dimensions of time within a business model. There is a lot of documentation, of messages and articles about dimensions. If you haven't already done so, check out page 126 of the Server Management Guide and read this article. That should at least help you get started on building your time dimension.

• Add time dimension

  Hi, I have a problem of modelling of the dimension of time for one of our facts (number of employees). The problem is this - when a user says "I want to see the number of employees for a specified period of time" - what they mean is that they want to see the number of employees as of the last day in this time. i.e. "June employee account" means account from 6/30, "year 2000" used average account at 31/12/2000.»
  
  This is very similar to a problem of type "end of record" modeling in OBIEE inventory.
  
  I solved this (badly) in OBIEE by changing the aggregation to use "LAST" for the dimension time and 'count (distinct (emplid))' for everything else. It works... but... the performance is terrible. If I ask account used for the year 2000, seems to lower the number of employee for all 365 days of the year, then sort by date, and then throw it away with the exception of the last date. In other words, it brings back 364 days of records and then throws. This makes the query perform absolutely terrible. 2 or 3 second query eventually run for minutes.
  
  Someone at - it another way to solve this problem?
  
  Thank you
  Scott

  Ah yes... the bane of the 'bewtween joins";)

  TBH, I think that a little magic LTS will be easier (if you can use that word here) solution and save you from creating a table on overall measure containing monthly aggregates... making it would be yet another option: create a monthly global chart that refreshes the current month once a day (to have one LAST progresses) and hangs at the end of the month.
