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?.

Hi there,
This forum is for Oracle OLAP. The Essbase forum can be found here:- Essbase

Modifying the time Dimension in OWB10G R2

Hello,
I've used the time-dimension wizard in OWB10G R2, but I am encountering some problems. Let me explain:
When you start with the wizard, it gives you the choice of a normal hierarchy based on year and/or quarter and/or month and/or day OR a week hierarchy, based on week and day. But I need a time dimension based on year, month, week and day. So I created a normal hierarchy time-dimension based on year, month and day and tried to alter it, by adding a week as an attribute (and level etc.).
So far no luck. I can't change the dimension, once it is created. Same for the other way around: create a weekbased hierarchy and ad month and year to it as attributes.
And now my question: Am I overlooking something? Or is it just a case of bad luck and do I have to build the time dimension myself by hand (not that much of a work, but still a pity of the wizard)? Or is there an other way around to fix this problem?
Regards,
Ingmar

Ingmar,
I just read your post and I am trying to accomplish the same thing with the time dimension - can you help me or direct me to another post that can?
After I create the time dimension with the wizard, I go back in via the Object Editor and I see the check box on the Levels tab and I have checked the Calendar_Week and all the attributes pop up, so far so good, then I navigate next to the Hieararchies tab and I don't see that the Level for Calendar_Week has been added?
How to I get a time dimension that has a single hierarchy that roles up as follows:
day ----> week ----> month -----> quarter ----->year
thx

Is it possible to add an all time member to the time dimension

We are on BPC 7. Our time dimension has the normal Year, Quarter, Month rollup.
Is it possible to add an "All_time" member to the time dimension that would have all years rolling up to it or are our only choices Year, Halfyear, Quarter, Month, Week, or Day?

TOTAL is not a valid selection for LEVEL. Did you create this "TOTAL" manually some how? I have seen "TOTAL" as a period but never a level. Do you have a dimension file that you can get to work with this example in APPSHELL that you could share?
According to the BPC Admin documentation it only comes with YEAR, HALFYEAR, QUARTER, MONTH, WEEK, DAY as valid options. How do you get the TOTAL member added as a valid option for the LEVEL property:
BPC Documentation Reference below:
LEVEL
Time can be a year, quarter, month, week or day. As described above, the PARENTH1 property is used to define the aggregation of the time periods.
The LEVEL property is also very important in defining your time periods. You must have the correct Level (Year, quarter, month, etc.) for each member. You must follow the chronological format throughout the Time dimension. The correct format is:
·        YEAR
·        HALFYEAR
·        QUARTER
·        MONTH
·        WEEK
·        DAY

How to build dynamic time series for the time dimension

I am planning to build dynamic time series using rule file instead of manually.Please let me know if there is any property need to assign to enable DTS property for TIME dimension.
Edited by: 844104 on Mar 14, 2011 3:37 AM

In the load rule in the dimension build settings you would need to go to the tab dimension definition, choose the time dimension and right click on it. Select Edit properties. If you have not done so, set the dimension to be the time dimension. Then go to the generations/levels tab and set the generation names you need. For example if you want YTD, you would set the generation name to Year, if you want QTD set it to Quarter. You would set the number to the generation number that coorisponds to the generation. The DBAG has the list of names for all of the DTS members.

How to build the members in essbase based on levels using EAL

Hi All,
How to restrict the members to build the in essbase based on levels using EAL.
I've requirement, in one dimension, needs to build the one level1 member as level0 in essbase.
please let me know the procedure, if any one implemented or face similar.
Thanks in advance,
Kiran

there's no such functionality in EAL to create Essbase outlines based on levels. the only workaround to this is to use Mapping tables:
1- create the dimension in essbase with the desired HFM level 1 members as level 0.
2- set this specific dimension to mapping in your design grid within your EAL Bridge
3- create the SQL Mapping table and start mapping those members from HFM to Essbase.

How to populate the time component of a cube?

We have a question regarding how to populate the time component of a cube. Let me explain:
We are using OWB 10gR2. We have created a cube with several dimensions. We are now building the mapping to load the cube. The cube operator has two columns for every dimension (e.g., "customer" and "customer_id" for the "customer" dimension).
We understand that, in this case, "customer_id" stands for the dimension business key, so we create an arrow from the business key in the source table to the "customer_id" column in the cube operator.
So far so good. The mapping works all right, and the cube is loaded correctly.
Now we need to do the same for the time dimension. We have already created the time dimension and we have loaded it. We have also included it in the cube, so now we have two new columns in it: "time_day_code" and "time", both NUMBER data type.
We have the "sale_date" column (DATE data type), in the source system and, of course, now we want to populate the date column in the cube. We suppose that, somehow, we have to translate the "sale_date" field into the numeric column of the surrogate key of the time dimension. How should do we do this? I suppose that OWB must do the translation for us, just as it does for the other dimensions, but how? We have been looking into the manuals, and we have found no explanation on how to go about this.
Any help would be appreciated.
Best regards
Juan Algaba

Hi Juan
You are right this should have been in the manuals, checked and there is only a brief mention (Using a Time Dimension in a Cube Mapping section)
The identifier format should have been documented for each level and will involve creating the formatted attribute for input to the cube operator's time dimension reference attribute.
The time dimension business keys are stored as follows;
Day Level - YYYYMMDD
Month Level - YYYYMM
Week Level - YYYYWW
Quarter - YYYYQ
Year - YYYY
If you have a source that has a SQL date datatype for example and want to construct the key for a cube's time dimension at the day level something like the following expression can be used to construct the time reference from a SQL date...
to_number(to_char( time_key, 'YYYYMMDD'))
The result of this expression can be used as input to the cube's time dimension attribute.
Cheers
David

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 create an attribute dimension in Essbase Studio?

I cannot figure out how to create an attribute dimension using Essbase Studio. The online help states that I need to "Find the Attribute settings grouping in the center" of the member properties dialog box. I suspect that I'm having a problem figuring this out because I don't have the attribute dimension properly defined in the relational data source or in the mini-schema. I've tried creating a table with no key relationship to the other tables and with no logical joins defined, but that doesn't seem to help. Any ideas?

so in the 11.1.1 version you would click on the member name in the hierarchy you added to the Essbase model and in the center pane of the general tab should be the attributes settings section.
If I had a dimension called stores wth two groupings unser it region and store_type, I would click on store_type and add the attribute info

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,
G

Populating the time dimension in ODI

I need to populate my time dimension in ODI> I read a solution in this forum suggesting to create a time table/view in the source schema, reverse it in ODI and then use it as source to populate the time dimension. Is there another way to do this? One way I thought of was to use the ORDERDATE field in my ORDER table (my source table in Oracle) and map it to my time dimension in SQL Server via an interface. But I also have DUEDATE, SHIPDATE and PAYDATE fields in my ORDERS table and this approach would mean that I have to map them through separate interfaces to the time dimension as well. I have created a procedure in the source schema(Oracle) and want to use it in ODI to populate the time dimension. But I amnt sure if that is possible in ODI. Could anyone help me with this please?

Neel

Hi Neelab,
Sorry for my delay to reply you, I had no time the lasts days...
To get the four distinct key from your time dimension, just add four instance of dimension table at interface each one joined with one of the columns.
I believe that you load your time dimension from some other table than PRJ_TBL_TRANSACTION because you have the HolidayType column in your time dimension...
A view is one possible solution to load the time table but depends how the performance of the query is.
A way to do it at ODI is:
- Create 4 interfaces, one for each column, to load 1 singe table with 1 single date column, don't worry about duplicated value at this time, than you can just use the "IKM Control Append" that has more performance but check the "Distinct" box (flow tab) at each interface
- Create a last interface from this temp table as source, to the time dimension target table. Now you will use the "IKM Incremental Update" and do choose the "Update" option to "NO". Check the "Distinct" box.
As this table will have no more than 6.200 records from the last 20 years it will be a small table where you shouldn't have performance problems.
These are some of possible solutions but I would like to add other "way to think".
By the table that you show here you have a simple time table with no special feature, for that, let me suggest you other way.
- in the current way you will join but didn't get the record that "fail" from the join once they will be exclude if a date do not exist at time dimension
My suggestion:
- Load the dimension time table from your source table
- as PK in time dimension table, use the ''Julian Day"
- At ODI target fact table (datastore), create a 4 reference constraints (one by column) to the time dimension
- at interface do not use the dimension as source and transform the 4 date to Julian and let the 4 constraints take care if they exists or not at dimension table.
OR
- Look for the minimum "possible" date at your company
- populate your time dimension with every each day since then until a future date (Dec 31, for instance)
- create a process to populate the future date that will be execute in a interval that you decide (once a year, once a month, as you wish) dependent on how further the date is populated
- use the "Julian date" as PK
- At interface just transform any date to "Julian Date" it will be at dimension time once it is naturally unique
You could substitute the Julian date for "YYYYMMDD" that is a unique value too.
I presented you 2 way to consider be considered, each one could be used based on how important is for the business know if a date was loaded or not.
Someone can question that has the dates loaded from source against has all dates previous loaded could help to find errors from days that wasn’t loaded but it has a failure. As there are 4 dates source columns (and we are talking just about one source table until now) if a date loaded math a date when the load failure there is no value in use the time dimension date to analyze this possibility.
I defend the full time dimension load.
Make sense and/or help you??

Locking Periods using the Second Hierarchy in the Time Dimension

Hi,
They are not usiing work status for this...
I am at a client, and they used the second hierarchy in the time dimension to lock periods. If they left the second hierarchy blank, no data can be written to it. To open the open the period, they code the Second Heirarchy with CONS_OPEN. Just wondering if anyone has information on this?
It was working fine, then we needed to run a transport to move BPC to a new machine, and it stopped working. Not sure if anyone has done it this way before?
Thanks,

Dear Kacper,
the way I understood, there are two separate questions in this post, namely:
I'm using a shared resource in multiple actors, and the code accessing the resource can take quite some time to execute. How can can I ensure this does not mess up the timing of one or all accessors?
I'm using a shared resource in multiple actors, and the code accessing the resource can generate errors if I try to access it from multiple places. How can I ensure synchronization between all accessors?
As for the first question, the optimal solution to separate the resource prone to timing issues in a different thread/actor. Put anything that is not strictly timed (file access, network comunication) in a separate loop. For each actor, you will get queue references to communicate with, so instead of logging the measurements in the actors where they are made, just queue them up for a different loop to process.
For the second part, the same logic still applies. Ideally, every singular resource should be handled by its own thread and nowhere else, so if anything else needs data from/to said resource, it can send a request to the dedicated thread or actor.
If, for some reason, this is not sufficient, you have to handle synchronization in some other way. There are a lot of techniques here, for example:
Create a named semaphore or lock as a part of the class. Have class functions use the semaphore before accessing the resource.
Use actor messages. Have a "resource in use" or "resource released" messages sent to all users whenever obtaining or releasing said resource.
Have a separate actor handle all resources, awarding them to threads needing them. This method also allows setting priorities between requests.
These are just a few examples, there are many other options.
Please let me know if this was helpful.
Kind regards:

That it is still working is miraclous.. most have died.. lots started flaking out at 18months to 2years..
See deadtimecapsule.org
The few that remained now seem to have reached EOL.. you can repair if you have some skills.. fairly cheaply.
But it is well and truly time to replace.

How to display the time 00:00:00 as blank?

Dear Friends,
I have created a new field GDF_9000_CREATED_AT in the normal screen (dynpro), the format is TIMS, however, when there is no value for it, is always display like "00:00:00" on the screen.
So how to display the time 00:00:00 as blank in the normal screen (dynpro) when there is no value for it?
Thanks a lot!!

In screen PBO module:
        LOOP AT SCREEN.
          if screen-name EQ 'my_time' AND my_time EQ time_zero.
            screen-invisible = 'X'.
            screen-active = 0.
            MODIFY SCREEN.
          endif.
        ENDLOOP.
I don't try this, but i think is true...
