Deleting MultiCube deleted all dimension tables of underlying BaseCube

Hello,
I recognized that the MultiCube wasn't what I needed and decided to delete it.
Normally, deleting a Multicube isn't a problem and it has no influence on the InfoCubes that belong to him. But now we had a bad surprise. Deleting the MultiCube stopped with error messages whicj said that some tables couldn't be deleted.
When I examinded the table names I saw that BW tried to remove all dimension tables of one of the physically InfoCubes which belong to the MultiCube.
I guessed that the warning wouldn't lead to a data loss but when I tried to check data directly from the physical cube I got a new error message: One of the dimesion tables are unknown. Then I tried to check all dimension tables of the cube. They are all lost
I checked the tables in SE11 and saw that they aren't tables any more but structures.
Any idea what could have happened in this case?

A multi-cube is a union of basic cubes. You can cross check tables RSDCUBEMULTI or RSDICMULTIIOBJ.
The multi-cube itself does not contain any data; rather, data reside in the basic cubes. To a user, the multi-cube is similar to a basic cube.
You may have a look at the following tables to check the data
/BIC/F* Info cube F-Fact table
BIC/E* Info cube E-Fact table (compressed records)
/BIC/D* info cube dimension tables

  • ADF delete from more than one table with single delete operation

    Hi all,
    I have a scenario in which I am trying to delete record(s) from 3 tables.
    My jspx page looks like this:
    Column1:drop down from 1st table
    Column2:drop down from 2nd table
    Column3:drop down from 3rd table
    Delete Commit
    I have created a view object which has these three tables as entities. I drag dropped the view object and displayed these three columns.
    Now when i select any one or all three or any two out of these and click delete, only the "column 1" gets deleted from 1st table. The remaining two tables remain unaffected.
    Y is this so?
    Can't I use one delete operation for all three tables' DML operation in single go?
    Thanks.

    If you have a business case that requires deleting from 3 tables at once when removing a single row in a view object then you may look for the problem in you data model...
    Until then I'd suggest to create a database view providing the information you need (plus the PKs fron the individual tables) and creating entity and view objects based on this view. An "instead of dele" trigger attached to the view can do the actual delete operation on the 3 tables.

  • Measures from dimension table

    Hi,
    Here is part of my logical layer (BMM):
    Dim - Time: TIME_KEY, ...
    Dim - Client: CLIENT_KEY, ...
    Fact - Encounters: # Visits ( i.e., count(distinct(EVENT_ID) )
    The above fact table contains foreign keys (TIME_KEY, CLIENT_KEY, etc.) to all dimension tables in the physical layer.
    My requirements:
    I need to generate a pivot report that has the following information:
    Rows: Translated categories based on # Visits (from Fact - Encounters)
    Columns: Fiscal Year (from Dim - Time)
    Measures: # distinct Clients (from Dim - Client)
    Somehow I could only get the correct measures when I used aggregation rule=count distinct for the CLIENT_KEY column in the "Dim - Client" table in the "presentation layer". However, I know this is not the right way to do that because all measures should be calculated based on the "fact" tables. Then, I even tried to create a logical fact table based on the same source as the "Dim - Client" table but got all zeros in the measures. Does anyone know the correct way to implement this logical layer?
    Thanks.

    Can anyone help?

  • Dimension table indexes

    All dimension table, non-key columns
    should have individual bitmap indexes.
    All fact table, foreign key columns must
    have individual bitmap indexes on them.
    By doing the above will the performance for joins be better.?
    Rakesh

    Well do remember bitmap indexes are best on columns where there not so many unique values. Everyone has differing opinions on what that # ought to be. In other words, the cardinality, or # of unique elements is not extremely high.
    IN general, bitmap indexes will improve performance given that the CBO is using them.
    Look at this post, it is a pretty good discovery on this sort of thing. it tends to be a design process, where you test with your given dataset and optimize it.

  • Delete Fact and Dimension Tables

    Hai All,
              Small question! When deleting data from info cube, it asks whether to delete just Dimension table or both fact and Dimension tables.
    What is the difference between these two?
    Thank you.

    Hi Visu,
    The dimension table will contain the references to char value by way of SID and DIM ids, whereas the fact table will contain the number (of key figures). If you delete just the Fact table, the numbers go away, yet the DIM ids remain intact, so reload is faster. But if you are convinced that this data is not correct either, or you want a clean slate to strat reload again, then delete both Fact and Dim tables. Then when you reload, the DIM ids will be created again.
    Hope this helps...

  • Dimension Tables deleted

    Hi BW Experts,
    Recently we loaded SD data. There are 6 data sources and we got 6 requests in Manage screen and got transferred/added records. There are about 8 lakh records. (INITIALIZATION)
    When i check the contents, iam not able to see the data in Infocube.
    We found the problem that Dimension Tables data deleted and we are able to see the fact table data.
    So please can anyone tell me the solution??
    Regards
    Anjali

    Hi,
    right click on the cube and select delete data. It will ask you options that you want to delete data from only fact table or fact table and dimension table.
    select the second option i.e. "fact table and dimension table", it will delete all data from fact table and dimension table drops them and recreate them.
    then you can do the data load again.
    Regards,
    Purvang

  • Dimension tables not deleted when cube data deleted

    We are using a process chain to delete the entire contents of the cube prior to the next load.  Over the course of time repeating this everyday, we see that the RSRV check tells us that the "MAX % ENTRIES IN DIMS COMPARED TO F-TABLE"  = 4718% !!  How can this be if each day the data is getting deleted from all related tables?  The max could only be 100% then, correct?
    Please advise.  I could not find an OSS note that the dimensions are not deleted as well with that step in a process chain.
    Thanks, Peggy

    Hi,
    we have fixed it call creating our own ABAP code with the following CALL:
      CALL FUNCTION 'RSDRD_DIM_REMOVE_UNUSED'
          EXPORTING
            i_infocube        = YOUR_ICUBE
    OPT       i_t_dime          = YOUR_DIMENSION
    OPT       i_check_only      =
          IMPORTING
            e_repair_possible = tp_repair_possible
    OPT     CHANGING
    OPT        c_t_msg           = it_msg
          EXCEPTIONS
            x_message         = 1
            OTHERS            = 2.
    (inserting code in the new SDN frontend is a bit of a nightmare...)
    and included this ABAP in the chain
    You can also go via RSRV and do that manually.
    I don't recommend to delete the whole dim table since the loading time will be drastically higher if you have your DIMS empty...
    The above works as well for aggregates...
    hope this helps
    Olivier.

    help ???

    Hi,
    Depends how you defined referential integrity.
    You can use ON DELETE CASCADE, please read the next doc http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/clauses3a.htm#1002692
    Hope this help you,

  • I just downloaded 950 photos on iPhoto and deleted them off my camera and now under last import there is only 4 photos and i can't find the others?? There is a whole bunch of blank events in the library with no photos in them all with todays date? Help!!

    I just downloaded 950 photos on iPhoto and deleted them off my camera and now under last import there is only 4 photos and i can't find the others?? There is a whole bunch of blank events in the library with no photos in them all with todays date? Help!!

    Yes - you need a min of 10 GB just to operate - with just 1 you certainly can lose photos and other critical things - you need to make space immediately - probably by moving your iPhoto library to a volume formatted Mac OS extended -
    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

  • Deletion of Dimension Table data in Process Chain Step

    Hi,
    I am trying to delete the InfoCube Contents using a Process Chian.This process is successfully deleting the Fact table contents, but not dimension table contents.
    I need your help to automate the deletion of dimension table contents.
    FYI--
    We are using BW 3.0 B.
    Thanks in Advance.
    Vardhan.

    Hi
    Unfortunately is not possible. I had in the past the same issue and I had also a confirmation from SAP.
    You can use RSRV to delete unsed value, manually or build a program.
    the process chain allows only to delete the fact table.

  • One Dimension Table Deletion issue

    Dear Guru's
    Query run's very long time to execute in prod system
    In our production system, we have a Cube in which one dimension(Eg:- /BIC/PC_17 which show 38% when i run report SAP_INFOCUBE_DESIGNS  ). Due to the performance issue of the Query, i am thinking to delete data from SE11 only for this dim table...What will happen with the Factable?
    Since Dim table has reference to Factable...Is it correct if i delete the entries for this Dimension table for the perfomance issue?
    PLease suggest me i am very much confused, also this is a prod system....so pls give me only good answers..no gess please...
    Also ....suppose if this Dim17  is not used in Query Does it make sense to delete entries from this Dim 17 for Query performance, since this exist's in cube...
    Thanks in adv,
    Dev

    Hi,
    you should not do that. In no case. There are some ways to speed up a query. Use them: e.g. building aggregates, running rsrv to check the cube and possibly have unused entries of dimensions deleted, compress the cube....

  • Hi All,How2 delete a pkey for std table and add 2 new primary keys

    Hi All,
            How2 delete a pkey for std table and add 2 new primary key fields .Please provide me the required procedure .
    Thanks&Regards.
    Bharat.

    Hi Bharat,
    First thing is you need to have the access key to change any standard dictionary object/standard programs/ standard transactions.You may get this from your basis person after getting approval from your respective manager.But changing or modifying the standard object is not recommended, but if there is no alternate to meet the business requirement then we have to follow this way only.
    Next, you need to check whether this table's primary key is being used in any other table as foreing key or not. If there is, then you must remove this relation and then you can delete the unncessary primary key field from that table.Finally you can add the two new fields and set them as primary key, save, check for any errors and activate.
    Hope this helps.
    Please reward if useful.
    Thanks,
    Srinivasa
