Consume Attribute view in Trial

Hi there,
I'm testing the Trial version of SAP HANA Cloud and wanted to create and consume an attribute view.
I have created a very simple view which uses a table from the EPMSAMPLEDATA schema.
Because of the isolation requirements I've executed the following SQL as mentioned here:
CALL "HCP"."HCP_GRANT_SELECT_ON_ACTIVATED_OBJECTS"
Now, the _SYS_BIC schema is visivle and I can find my View there. But when I right-click on my view and click on "Open content" I get an authorization error:
Could not execute 'SELECT * FROM "_SYS_BIC"."p1234trial.myhanaxs/ATT_VIEW"' SAP DBTech JDBC: [2048]: column store error: search table error: [2950] user is not authorized.SAP DBTech JDBC: [2048]: column store error: search table error: [2950] user is not authorized
Do I miss something or has something changed?
Thanks for any help,
ben

Hi Priya,
thanks for your answer.
As logon user I'm using the username/password which is given to you after you've established the database tunnel via the "neo open-db-tunnel" command.
Regarding to the other priviliges:
Which user do I have to assign which priviliges?
As I undestood from this tutorial there is no need to assign specific priviliges.
Greets,

Not able to view Data Preview of Attribute View,AV and CV

HI,
I have created tables and then created the required attribute view, analytic view and calculation view for parent child hierarchy.
I'm facing two problems
1. I'm not able to see the "Data Preview" of any of the views.
2. When i'm trying to import data from HANA from MS-EXCEL 2010 with data connection wizard, then connection is established successfully but after that instead of showing cubs its giving the following error

SAP HANA Attribute View- Not able to add objects

Hi All,
I've created one attribute view in Modeler Perspective.
Trying to add tables on data foundation using "Add Objects". But when table name is entered in pop-up window, it hangs (not-responding). And error log got created as below.
I'm not able to add the tables.

Hi Sujit,
The log seems that connection is closed. Is it true? Did your system restarted?
What happens if you close the studio, open it and try again?
Are you using same revision Studio than the database?

Hi Suma,
Post the SQL you success run directly on Studio together with error message (even if is the Invalid column index error).
Check there if the parameters case is working properly... Is it really this confusing options:
p_GJAHR
S_BUKRS
p_base_ledger
Why not all lower or all upper? Anyhow you must test and find which option works according your modeling

Doubt in attribute view on joining the table .

Hello Team
                    Can some please help me in clearing the following doubts on joining tables .
i) Can we perform a self join in attribute view in HANA . like for ex :- joining a table to itself .
ii)Can we create an analytic view without creating an attribute view i.e creating an analytic view directly on tables .
iii)When aggregation happens in calculation view exactly what happens internally .
Please suggest me with the solution of these doubts .
Regards

Hi Prag,
As Rashmi has answered your question, i would like to add up to it few more important points.
1. Do not perform self join as it will return uncertain results. It is better to avoid self join.
You can create a copy of the same table and perform join which will be consistent.
2. In an analytic view, you will be adding table to data foundation, select the output fields.In the logical join node by default your data foundation will be present (this will contain the fields that you selected for output), you need not add any attribute view to this logical join node, leave it to default. In the semantics node select the attributes and measures. Perform validation and then activate. Your analytic view without attribute view is ready. You can check the data preview.
3. In a calculation view, the records gets grouped by all the attributes and then the measures are calculated based on this grouping by using the mentioned aggregation (sum/max/min).
Eg.
Customer ID 0Calmonth Amount (aggregation = max)
1001               01.2014     100
1001               01.2014     400
1002               01.2014     200
Output:
Customer ID 0Calmonth Amount (aggregation = max)
1001               01.2014     400
1002               01.2014     200
Hope this clarifies your doubts.
Thanks and Regards,
M.N.Adinarayanan

Using Attribute views in Script based Calculation views

I am trying to create a view for analysis on a fact table which has measure name as a dimension as opposed to having multiple measures. Here is an example of what the data looks like.
#Customer, Product, Measure, Data
Customer1, Product1, ASP, 4.2
Customer1, Product1, Units, 100
Customer2, Product2, ASP, 4.4
Customer2, Product2, Units, 200
... and so on and so forth.
I had build Attribute views with hierarchies for both customer and product dimensions and build analytic views. However now I have the need to flatten the Measures dimension and have the resulting Fact view look like:
#Customer, Product, ASP, Units
Customer1, Product1, 4.2, 100
Customer2, Product2, 4.4, 200
... and so on and so forth.
Now I want to build analytic views on this flattened view of my Fact table.
I was able to create a calculation view using Script mode, on the fact table and write a SQL to flatten the Measure dimension. But I am not able to now join this calculation view with the attribute views. Is there a way to leverage the existing Attribute views and their hierarchies in this case?
The only way I can see for now is to use manual SQL to build out the entire view, including joining the attribute views and re-build the hierarchies in the definition of the calculation view. This essentially wastes work I have already done in the attribute views and forces me to build the entire thing using SQL.
Is there a better approach?

It's extremely annoying that the FLD() command isn't yet availlable in NW, unless it's coming with 7.5 or has been included in one of the more recent support packs.
As a an alternative you may be able to use the following MDX routine:
Returns the value of a property of the current member of a dimension
*function PRO(%DIMENSIONNAME%,%PROPERTYNAME%)
%DIMENSIONNAME%.Properties("%PROPERTYNAME%")
*endfunction
Unfortunately I've never been able to use this with a When statement, so you may have to ask an ABAP resource to develop a BADI to achieve your required results.

Calculate Column Subtotal in Attribute View

Hi,
Is it possible to calculate the Column subtotal in Caluclation View itself likethe way we do in ALV.
I want to do this calculation in the Calculation View itself.
I thought of doing that through Calculated Column but the SQL Function SUM() doesn't work there.
Below is how my Calculation View looks like:
I want the output to be like this (Highlighted in Green):
I am getting the field Allocation from my Attrbute View ZAT_VBRK_VBRP(Join of table VBRK and VBRP) and ZVBAK is just an attribute view for VBRK.
Thanks,
Gaurav

Hi Shankar,
Sub_totals can be achieved through the SQL query using the Grouping_sets which is something like this,
select col_1, col_2, col_3, sum(col_4)
from <Table_name>
group by grouping sets LIMIT 2 WITH SUBTOTAL
((col_1, col_2),(col_3));
Usually this can be done in the front end reporting tool but,If you want to continue with the calculation_view where you want the sub total to be appended as a "New Tuple" then you will have to go with the CE_Functions using the sql_query.
This is something new that i can learn today, lets see how the experts will guide us with the approach.

Krishna.

Consume HANA Views

Hello,
We are migrating a report from ABAP to HANA due to performance reasons. We have created various views for data selection and aggregation.
My query is how to consume these views created, via External view Or Native Sql(ADBC) which is better option in terms of performance optimization.

Hi Jitendra,
I think this question is touched/commented on in http://scn.sap.com/message/15268054#15268054, right?

How to get the distinct values in Attribute View?

Hi,
While doing the data preview of attribute view its showing duplicate records.
Can i restrict all these duplicate in attribute view and get only distinct values?
Thanks in advance.

Hi Deepak,
Please check the Key Attribute combination in the Source System and Create Attribute view with the same combination.
so that you won't get any duplicate values.
If you are taking fields randomly Pls ensure that you are taking at least one primary key combination use the same combination while creating Attribute View.
As u know that the purpose of Attribute view is to store the Master Data Objects like BI/BW which stores Non duplicate values.

Consuming HANA views using ABAP

Hi Experts,
We have ABAP reports in ECC which is taking very long time to process it. So we decided to push down the complex logic to HANA where ever it is taking long time to fetch data.
We have standalone HANA System. So can we use HANA as secondary database??? If yes, how can i consume HANA views in ABAP reports??
Can some one guide me.
Thanks in advance.
Best Regards,
Krishna.

Hi Sundar,
Thanks a lot for your valuable inputs.
You need to access the native HANA artefacts (like HANA information views) from your ABAP system using native SQL and ADBC in case HANA is not the primary DB.
- If i want to pass values to the views can we use HANA input parameters in this case as a PLACE HOLDER in Native SQL??? else do i need to create a procedure for it???
Basically ABAP team is optimized the code but still we are hitting with performance. So we want to utilize existing HANA databse as secondary db to push down the complex logic to HANA.
Best Regards,
Krishna

Unable to view columns for attribute views created

Hi all,
Here are the list of errors I am facing while creating attribute views and while adding multiple dimensions (Product dim and Employee dim) to an attribute view.
I am unable to activate my attribute view. I don’t get any error message other than:
Message : STS.STS_ATTRIBUTE_VIEW: one or more columns of Table: DIMSUPPLIER have invalid ABAP name
2. When I added DIM.Product attribute to the attribute view STS_ATTRIBUTE_VIEW, I am unable to see any column names for the DIM.Product to add them to output fields. Same with employee dimension also. Now my question is, Can I add more than one dimension to the same attribute view or do I have to create a new attribute view for every dimension. While I think I can add more dimensions to the same attribute view but I asked this question because I am unable to see any columns listed out in the dimensins Product and Employee.
3. In Employee dimension when I click on the data preview, I don’t get any data. Its all blank. But there is data in the table and its visible when I preview in table.
4. When I right click on the attribute view or the attribute itself I don't see any other options other than "Configure Table" but I remember 2 days back when I worked I was able to see other options like "Data Preview" and few others.
Why am I unable to view the columns of the Product and Employee dimensions? Should there be a common primary key between all the dimensions to be able to view the data in the attribute view?
Please note that my attribute view is still in grey inspite of hitting on save and validate and save and activate several times. And I am getting a warning message, "Some services are not started" on my hdbsystem and the system is showing yellow colour.
Please advise.
Thank you.
Regards,
Pavan.

Hi Pavan,
To much words and no picture, this doesn't help you to obtain community feedback.
Can you sintetize your question, maybe even split it in minor questions.
I confess I failled to understand what you are facing.

Filter in Attribute view

I basically want to have a view that displays two columns from my table, but not have any of the columns repeat the same ID or Name
For example if table data looked like this
Name ID
John 204
John 204
John204
Mel 205
Mel 205
Mary 205
I want the View to display
Name ID
John 204
Mel 205
Mary 206
I feel as though there is a real easy solution to this but I'm not sure how to do it.
Thanks,
Connor

Hi,
It will depends on ur data modelling.. and the logic
mainly 3 views
Attribute view - consists of dimension or master tables
analytical view - along with attribute view or some master tables it will have fact table or transaction table table (basically a numeric or measure column presenting in a table)
Calculation view - based on ur logic u can choose graphical/ complex -scripting methods...
(Graphical, scripting)
but in each step u should check the data integrity # no records retrieved are correct or not.., because in ur table if u r having composite relationships then data may go for looping especially when u r using analytical view..
so for simple architecture or aggregation columns u can go for analytical view
i enclosed file in which it explains the modeling structure on what purpose we need to use the 3 types of view..
hope this will help you.
Thanks,
Thara
