Mapping in AWM

In AWM, i created the dimensions ,mapped them to relational table.Then i created a cube,added the dimensions.while mapping the cube,when i map the cube to corresponding relational table and give apply,the mapping gets disappeared. i haven't come across this sort of behavior so far. why is that so happening? can any one pls help??

I saw issues like this in early 11.2 versions of AWM when you attempted to map to literal values. What version of AWM are you using? It could help if you describe the columns you are attempting to map, including the order in which you map them.

Build in OWB and make map in AWM?

Hi all,
Would it be possible to design and deploy the dimensional objects (dims/cubes) using OWB and make a mapping to populate them using AWM? These are all MOLAP objects. The advantage of designing in OWB is the editor and e.g. the ability to add calculated measures in cubes using the wizard.
Just did a quick test. When deploying a MOLAP dimension from OWB, in AWM it shows the map with several OWB-generated views to populate the object. I don't want to use those since I don't want to build a map in OWB. I have a simple 1-to-1 view to populate the object in AWM. However, when removing the OWB views from the map in AWM and replacing it by my view, when applying the changes it comes back with an error:
An error occurred creating DimensionMapGroup D_DIM_EMPLOYEE_M.TOTAL.MAPGROUP1.DIMENSIONMAPGROUP : ***Error Occured in DELETE_MAPPING_GROUP: You provided extra input starting at '$'.
The error detail window shows:

If this doesn't work it's just another blow to our olap-in-oracle implementation plan.
Does anybody have experience with this issue?

Mapping Dimension with a composite primary key in AWM

Hi, I have a dimension with 3 levels in a snowflake scheme. The Primary key (PK) of one of them is a composite pk.
Let's say: table1 (code_t1 (pk), desc_t1), table2 (code_t2 (pk), code_t1 (pk+fk), desc_t2)) and table3 (code_t3 (pk), code_t2 (fk), code_t1 (fk), desc_t3), being table3 the base level table.
I am using AWM 11.2.0.1.0A
My questions are:
1) can I have a level with a composite PK?
2) if yes, how should I do the mappings using AWM? It seems like you only can have one filed for the source column in the Mapping pane.
3) if no, is there any workaround?
Thank you.

I just tried this in AWM and it is clearly buggy in this area, in part because it is trying to change the underlying representation.
If you export the dimension to XML you should find an entry that looks like this for each level
<HierarchyLevelMap
KeyExpression="..."
Query="..."
JoinCondition="...">
</HierarchyLevelMap>
The 'Query' is the name of the table you are selecting from. For example, your level2 should have
Query="TABLE2"
The 'KeyExpression' is the expression that defines the AW dimension member for that level. For example, your level2 should have
KeyExpression= '(TABLE2.CODE_T2 || TABLE2.CODE_T1)'
The 'JoinCondition' defines how to join the table for a child level to that of its parent. For example, your level3 would ideally look like this
JoinCondition='(TABLE3.CODE_T2 = TABLE2.CODE_T2) AND (TABLE3.CODE_T1 = TABLE2.CODE_T1)'
But in your case it must be something different, probably 'TABLE3.CODE_T2 = (TABLE2.CODE_T2 || TABLE2.CODE_T1)'.
AWM must derive its Parent field from this JoinCondition in some way, and it appears to mess it up when you use concatenated key expressions. The workaround is to hand edit the XML to specify the JoinCondition correctly for your case and recreate the dimension from that XML. I would then avoid editing this particular mapping in AWM since it will mangle it.

Mapping "Time-variant"dimension

Hi,
how can I map in AWM a dimension which has a level "time-variant"? Maybe I must add to the dimension a level which refers to key of Time Dimension?
Thanks
Giancarlo

Giancarlo,
Thanks for the tables and mappings. It always helps to have specific details. The next question is how do you want to report this data? I assume you want to know the total revenue by city and date. E.g.
select sum(revenue), c.city, t.month_id
from
customer_dim_table c, time_dim_table t, fact_table f
where <natural joins>
group by c.city, t.month_id
I assume you also want to know the result by customer name (which I will assume for the sake of argument is a unique identifier). E.g.
select sum(revenue), c.customer_name, t.month_id
from
customer_dim_table c, time_dim_table t, fact_table f
where <natural joins>
group by c.customer_name, t.month_id
Finally, I expect you want the same thing where the group by doesn't include month. e.g.
select sum(revenue), c.customer_name
from
customer_dim_table c, time_dim_table t, fact_table f
where <natural joins>
group by c.customer_name
Is this accurate? The answer will help determine a proper hierarchy structure for the customer dimension.
On another issue, are you only interested in the simple aggregates or do you also want calculated measures (such as year to date)? The answer to this will let me know if you could use rewrite on a cube materialized view, which simplifies matters a little.
One more question. How are you using the 'validity' column? Specifically, what happens if customer 'Patrick Jackson' remains in NY for another month. Will you add a third row (with validity = 3) or are you assuming that the system is smart enough to know that if there is no validity = 3 row, then it should look for validity = 2 (etc)?

OLAP kinda dumb question....

Ok, I know its no longer required in OLAP 10g to create a CWM cube first, but if I have a relational cube with associated CWM entries, is it even possible to create an AW based on it any more? Or do I have to recreate all the dimensions, cubes, measures, etc.?
p.s. there used to be a wizard to do this, but I don't see it any more.
Thx,
Scott

Hi,
I did this recently in a project. If its the the 100% right way to do it I'm not sure but it worked for me. I did it only for the dimensions however as I wanted to be 100% sure that the cube was created how I wanted.
First I created an AW using AWM where I wanted all the dimensions. Next I populated and ran this script:
set serveroutput on
execute cwm2_olap_manager.set_echo_on;
DECLARE
v_dimension_owner VARCHAR2(20):='DW_DM_TEST';
v_dimension_name VARCHAR2(20):='DIM_TEST';
v_aw_owner VARCHAR2(20):='DW_OLAP';
v_aw_name VARCHAR2(20):='AW_ORDER';
v_aw_dimension_name VARCHAR2(30):='AW_DIM_TEST';
v_AWDimload_spec_name VARCHAR2(20) := 'order_test_load';
BEGIN
dbms_aw.AW_ATTACH(v_aw_name,true);
DBMS_AWM.CREATE_AWDIMENSION( p_Source_Dimension_Owner =>
v_dimension_owner,
p_source_Dimension_Name => v_dimension_name,
p_AW_Owner => v_aw_owner,
p_AW_Name => v_aw_name,
p_Target_Dimension_Name => v_aw_dimension_name);
DBMS_AWM.CREATE_AWDIMLOAD_SPEC(
p_AWDimLoad_Spec_Name =>v_AWDimload_spec_name,
p_Dimension_Owner => v_dimension_owner,
p_Dimension_Name => v_dimension_name,
p_LoadType_Name =>'FULL_LOAD');
DBMS_AWM.REFRESH_AWDIMENSION (v_aw_owner, v_aw_name,
v_aw_dimension_name, v_AWDimload_spec_name);
DBMS_AW.AW_DETACH(v_aw_name);
COMMIT;
END;
This also populates the AW dimension. What I noticed if I didn't populate the dimension, the dimension had to be mapped in AWM. So for me it was easier to run this script, and maintain the dimension in AWM again, selecting the delete options for the dimension members.
I think theres a similar script for cubes also, but not sure if this allows you to set partitioning.
Hope this answers your question.

AWM dimension mapping - is it possible to load data from two input tables ?

Hello All
I have two tables ProductFamily (parent level) and Products (child level).
I want to load a dimension from these two tables where the parent-child relationships are maintained (I am using AWM).
I created a mapping with these two tables as input, but the data loaded does not maintain the relationships.
So how do I do that? Is it possible to load dimensions where different levels get data from multiple tables?
Is there any type of joiner available in AWM?
thanks
Few Notes:
- I do not want to use OWB here as my data is clean
- In AWM, When I loaded the data from a single view which contained data from both input tables, it worked fine. But this is my worst case option.

You should use the Snowflake Dimension option in the Dimension mapping screen for the Product Dimension (as opposed to the default dimension mapping style - star schema).
This will modify the mapping inputs to include a separate parent level key for each hierarchy/level i.e. for each hierarchy/level (unless topmost level of hierarchy), you need to specify the parent level key in addition to the current level key, code/name/description/other attributes etc.
You can do the mapping in either .... use icons at the top of the mapping screen.
the drag/drop mode by dragging the relational column onto dimension model - hierarchy/level/attribute
-or-
the table expression mapping mode which gives the same effect.. dragging a column onto an attribute sets the expression in <schema>.<table>.<column> format.
HTH
Shankar
Note1: Complete the mapping in one go.. Switching b/w the mapping modes cause the mappings to be reset.
Note2: Assume your data is correct, foreign key to parent level table: ProductFamily exists in child level table: Products.

AWM mapping : "SCHEMA.TABLE_NAME.COLUMN" invalid

Hi,
I have Views in my database that I use as dimensions .
In AWM, I create dimensions, I try to map with my views ... And I get the following error :
*"SCHEMA.TABLE_NAME.COLUMN" invalid*
I chekked the database, everything seems to be okey ! And I can't find a clue
Any Idea ? Thanks all !

Are you able to query from the database View without the error, and as the same login you use in AWM? Is the View valid/compiled?

AWM 10g: Cannot map "Total Level"

Hi,
I use AWM 10g and I can't insert a literal value for total level (for example 'TOTAL CHANNEL') of my dimension in mapping section.
How can I do? There's a workaround? Alternatively, can I insert in my dimension table two additive columns "TOTAL_ID" and "TOTAL_DESCRIPTION" and drag and drop them instead typing string 'TOTAL CHANNEL'?
Thanks
Giancarlo

Consider mapping to a view, with the literal included in the view. Mapping to views is a good practice because you can change the definition of the view (where the view gets data, change filters, etc.) without changing the table to cube mappings. You will find this to be a good practice in the long run.

AWM Plugins and Object View

I'm trying to create a java plugin for AWM that is only valid for items in Object view (eg Variables, Programs etc... all the primitive Express objects).
According to the interface defined for AWMPlugin methods:
void handle(Frame parent, Connection conn, String type, Object obj,
AW aw, Map param);The 'type' and 'obj' represent either a String or an Object that is associated with the selected tree item, or null.
My problem is that type and obj are always null when operating in Object view, but pass a non-null value in Model view .
Has anyone encountered this? Does it mean the AWM plugin interface is only valid for the Model view?
Does anyone know of a way to get a handle to something like a Variable or Program in Object view using the AWMPlugin interface?

I am certainly not an expert on this but this would be my thoughts on this topic -
AWM plugins are supposed to only work on model view since this view over the AW uses the public APIs called Standard Form. The Object view uses a non-public API which addresses the internal AW catalog (i.e. the NAME dimension). Therefore, it would not surprise me that the API you are calling returns NULL when you try to access non-Standard Form objects.
I will try and contact one of the OLAP PM's this afternoon and get his opinion and let you know.

Mapping Variables(Object View) to Measures(Model View)

Hi,
In my AW, I have created a cube, And then I have created a new variable in the object view and populated it using load programs. Now. when I try to create a measure in the model view of the same cube based on this variable, I cannot see any option for assigning a variable to a measure. Can someone please help me out in doing this?
I need the measure in the model view, because it looks like, when I create a relational view, only the measures that are defined in the model are added to the view and not the variables available in the object model.
Thanks,
Bharat

Hi Bharat,
The mapping editor is used to map a measure to a relational data source. Therefore, unless you convert your data source used by your DML program to a relational table/view (if it is a text file you can use an external table to present the data to AWM as a relational table, or if it is an Excel spreadsheet and your database is on Windows you can use the heterogenous gateway service to load directly from Excel by exposing the Excel worksheet as a relational table) you will not be able to use the mapping editor.
To assign an OLAP variable to an measure within a cube you will need to create a custom calculated measure. This will allow you to create a measure that "maps" to your OLAP DML program. There is an Excel utility on the OLAP OTN home page that allows you to create custom calculated measures (at the moment this feature is not AWM10gR2 - but is available within AWM 11g). Click here for more information:
http://download.oracle.com/otn/java/olap/SpreadsheetCalcs_10203.zip
My advice would be to try and convert your data source to a relational table/view and using the mapping editor. This will allow you to benefit from the many new features within OLAP cube storage such as compressed composites, data compression, paralled processing, partitioning and aggregation maps. Of course you can code all this manually but it is much easier to let AWM do all this for you via a few mouse clicks. Please note - that everything you build outside of the AWM model view has to be managed (defined, updated, backed up etc) by you rather AWM. So while there are lots of advantages of using OLAP DML, I personally always try to load data into my OLAP cubes using AWM mappings and save OLAP DML for providing the advanced types of analysis that make OLAP such an excellent calculation engine.
Hope this helps

Logical to Physical Mapping

Newbie to the Analytical Workspace Manager v. 11.1.0.7.0 and using Oracle Database 11g Enterprise Edition Release 11.1.0.6.0. Installed the global sample schema and associated objects. Created the workspace in AWM and I am able to see all cubes and dimesnion objects. I am now trying to do the logical to physical mapping of the dimension objects with the tables that I imported into the global schema. I right-click on the Channel dimension, but I do not see the Mapping option. I am unable to launch the mapping canvas. All I see is Maintain, Analyse, Set Security, Save, View Data and Delete. Am I missing something in the installation?
Thanks in advance for your help.

Mappings in OLAP using AWM

Hi,
I have a small problem while mapping table columns with dimension levels in olap using analytical workspace manager(AWM).
I have these levels
Item Level,Category,Sub Category,Finance Type,Finance Product.
I have these columns
inventory_item_id,item_description,segment1,segment2,segment3 and segment4
i'm mapping as follows:-
inventory_item_id to Item Level Member,
item_description to Item Level Short Description
segment1 to Category Member (as we should not leave this item unmapping)
segment1 to Category Short Description,
segment2 to Sub Category Member(as we should not leave this item unmapping),
segment2 to Sub Category Short Description ,
to my knowledge i think(not sure how much i'm correct) we need to map only number datatype columns to Member items and character datatype columns to Short description items.
For my segment columns there are no ids and all the segment columns are character type but segment1 becomes parent for seg2 ,Seg2 is parent of Seg3...etc.
Will i get into any problem if i use the mappings as above or there is any other way to map these columns.
Thanking You,
Kumar P.

Your dimension members don't need to be numbers. You measures probably should be numbers. Keith has said before that the shorter the dimension member keys, the faster OLAP will run. This includes picking short names for the levels for your dimensions. Since your dimension level names probably are not numbers, and the dimension values are concatenated with the level name, you can rest assured that your dimension members can be strings.

Mapping in Administration Tool

Hi All,
I have created in AWM two simple cubes and so two cubeview with VIEW Generator plugin
Cube 1:
DIM A
DIM B
MEASURE 1
Cube 2:
DIM A
MEASURE 2
First cube is based on fact table Budgets and second cube is based on fact table Actuals
So two Fact Tables have common dimension (DIM A)
If I try to drag and drop in Answers DIM A, MEASURE 1 it works, but if I add even MEASURE2, this one is empty.
Furthermore, if I drag and drop only MEASURE2, i receive error: [nQSError: 42021] Query doesn't refer to any table. I think it's a mappgin error. How must I map my two cubes in Administration Tool. In it I have mapped only one fact table with MEASURE1 and MEASURE2 together. Maybe i need two fact tables?.
P.S. I am newbye of Administration Tool, so I need an explanation step by step, or a tutorial.
All regards
Giancarlo
PS2. I've found following post. It's my same situation. But I don't understand well what i must do. Can you explain me?

The solution recommended when using NetMeeting across most wireless routers (like the Airport Express) is to use the router's "DMZ" function - which forwards ALL incoming ports to the private IP address of the PC laptop.
