How we can update cube using Change Tables as Source

I have created a cube using source tables. I have also created change table (feature of 9i) based on source table. which store new changes to souce table. I want to load cube using one mapping from source table or change table based on the validity of the change table.
Is that possible to do this? have anybody implemented change table to incremental load of cube?
Sanjiv Tyagi

Hi Sanjiv,
I can think of 2 ways of doing this:
one is using a single mapping with a pre mapping process to determine whether the change table is valid. If yes the pre mapping process creates a view (that is also referenced in the mapping itself) on top of the change table (select * from change_table), if this is not valid then the view will be on the source table (select * from source). After this pre map process the mapping runs on which ever view exists and loads the data.
the second way is using process flow and 2 mappings. In PF you have a PL/SQL call that verifies which data to use. If the change table is correct, that will give success and uses the mapping on the change table. If the return is Error then you use the mapping on the source table.
I have not implemented these solutions, however I think these are 2 ways of getting it to behave like you would want to...
Hope this gives you some ideas,
Jean-Pierre

  • How to create olap cube using Named Query Table in Data source View

     I Create on OLAP Cube using Existing Tables Its Working Fine But When i Use Named Query Table with RelationShip To other Named query Table  It Not Working .So give me some deep Clarification On Olap Cube for Better Understanding
    Thanks

    Hi Pawan,
    What do you mean "It Not Working"？ As Kamath said, please post the detail error message, so that we can make further analysis.
    In the Data Source View of a CUBE, we can define a named query. In a named query, you can specify an SQL expression to select rows and columns returned from one or more tables in one or more data sources. A named query is like any other table in a data source
    view (DSV) with rows and relationships, except that the named query is based on an expression.

    Hi, my trial version of Lightroom 5 has recently expired and I have now fully bought it. I have uploaded the CD onto my Mac, but when I open the Lightroom application again, it still says the trial has expired. Does anybody know how I can update it so I can finally use it again? I really appreciate any help!! Thank you!

    Joanne please remove your current installation of Photoshop Lightroom using the uninstallers located in the Applications/Utilities/Adobe Installers.
    You will then want to download Adobe Photoshop Lightroom 5.7.1 from Adobe - Lightroom : For Macintosh.  The update contains the entire application.  Photoshop Lightroom can not be installed through the Adobe Creative Cloud Desktop application and still be licensed with a serial number.

  • How we can update the time profile ?

    Hello,
    How we can update the time profile daily in PP/DS ?
    This time profile we need in the background job scheduling.
    Please suggest

    Hi Sunil,
    The Time Profile is first to be maintained by going to the current settings (S_AP9_75000087) and creating one Time Profile as per your requirements.Here you define the Display Period and Planning Periods. If you create Relative days/weeks/ months then it is calculated in relation to the current date.So for example if you want to view 10 weeks in past and 20 weeks in future from today, you give the Start Date as -10 and End date as +20.after selecting Relative month/week/day in the Daye column.
    Similar method is used for both the Display Period and Planning Period. Preferably ristrict the Display period.
    You also have the option of Absolute time where you enter the start date and the finish date as an absolute value in the set period type.This will hard code the dates for you.
    This Profile which you have created needs to be attached to Detailed Scheduling Planning Board - View 1/2/3 which ever you want to use by going to the Profile icon on the top and in the pop up click on the More profiles Tab and putting this value in the Time Profile Box.
    Thanks,
    Harsh

  • Can't i use temp tables in regions?

    Hi,
    I'm trying to population 3 years fiscal year data in a single row, one for full time and other one for part time employees. So my output should look like this
    Population Fy1_Tot Fy1% Fy2_Tot Fy1% Fy3_Tot Fy3%
    FT 500 50.0 700 70.0 9000 90.0
    PT 500 50.0 300 30.0 1000 10.0
    Each fy1 data represents different month, based on the month I have to populate corresponding Fiscal year and I have take care this.
    I could do this using TEMP table and works well in Toad but not in HTML DB? Can’t I use temp tables in regions?
    Please see the query below
    WITH TEMP AS(
    SELECT INITCAP(FIELD_VALUE) as Population,
    (CASE WHEN D_S_REP.SMC = :P14_MC_FY1 THEN TO_NUMBER(FYT3) END) as Total1,
    (CASE WHEN D_S_REP.SMC = :P14_MC_FY1 THEN FYP3 END) as FY1P,
    (CASE WHEN D_S_REP.SMC = :P14_MC_FY2 THEN TO_NUMBER(FYT2) END) as Total2,
    (CASE WHEN D_S_REP.SMC = :P14_MC_FY2 THEN FYP2 END) as FY2P,
    (CASE WHEN D_S_REP.SMC = :P14_MC_FY3 THEN TO_NUMBER(FYT1) END) as Total3,
    (CASE WHEN D_S_REP.SMC = :P14_MC_FY3 THEN FYP1 END) as FY3P
    FROM D_S_REP
    WHERE FIELD_NAME='POPULATION'
    AND RS_YR LIKE '%'||TRIM(:P14_S_YR) || '%'
    AND D_S_REP.SMC IN (TRIM(:P14_MC_FY1),TRIM(:P14_MC_FY2),TRIM(:P14_MC_FY3))
    AND WP_NAME = TRIM(:P14_WP_NAME)
    AND RDL_NAME LIKE '%'||TRIM(:P14_EMPLOYEES)||'%'
    GROUP BY FIELD_VALUE,D_S_REP.SMC, FYT3,FYP3,FYT2,FYP2,
    FYT1,FYP1)
    SELECT Population, SUM(Total1), SUM(FY1P), SUM(Total2), SUM(FY2P),SUM(Total3), SUM(FY3P) FROM TEMP
    GROUP BY Population
    Any thoughts!!
    Thanks

  • Using table comparison can we use multiple tables as source?

    Using table comparison can we use multiple tables as source?
    Thank you very much for the helpful info.

    Table Comparison
    1) Input Data coming in
    2) Comparison table (table to which the data is compared)
    3) Output (input rows with respective opcodes based on the comparison result of input dataset with the comparison table)
    If your question is whether table comparison can accept union/join of multiple table sources, you can achieve by using merge/query transforms and then feeding to table comparison. Here, you have to be careful about choosing the primary keys inside table comparison
