HANA calculation view, temporal tables and processing data by rows

June 6, 2016, 8:51 am
$

Hi,

I have a question about using HANA sql script in calculation view for BW.

I'm trying to move the logic from application server to HANA DB. And I'm trying to find some objects to process data row-by-row like LOOP in internal tables in ABAP.

The task is to realize some complex logic - to read data from 3 DSO, to calculate some fields, check some conditions and delete some strings in the result and so on.

 

I've read most of the topics founded by search on "temporal tables in calculation view", "loop in calculation view" and so on. And i've made several experiments.

From them i understood that:

  1. I can't use temporal tables in calculation view because calculation view is always read-only.
  2. I can't make another procedure, use temporal tables and call it from my calculation vew because read-write procedure can not be called from read-only procedure. So I can't use  temporal tables at all.
  3. I can use cursors but it is impossible to insert or delete some data in cursor.
  4. I've found a blog Using SQLSCRIPT ARRAY as "Internal Table" to deal with complex logic about using separate array for every field of "internal table" which i need. But as for me, this variant is too difficult in debugging, understanding, supporting and so on.

 

I understand that using joins and unions is preferable variant, but I think that my task really could not be solved by joins and unions.

Before HANA on classic BW I used a "virtual cube" technology for such tasks. I can return to processing data in ABAP in virtual cube for current task.

But before doing this, I'd like to ask: have I understood correctly that the variant with arrays from that blog is the only one possible variant of realizing "internal tables" in calculation views? If there are other variants, I'd be very glad to get some links to read, keywords, ideas and so on. Thanks.

Hi,

 

In my CV code, I have written

 

deals = SELECT quote_key,

                       deal_id,

                       deal_date AS "DEAL_DATE"

                  FROM "BASE_TABLE";

 

SELECT COUNT (1)

INTO x

FROM :deals;

 

Earlier it was running fine, but suddenly I have started to face the below error:

SAP DBTech JDBC: [2]: general error:  [2] "_SYS_BIC"."ABC/proc": line 332 col 3 (at pos 12649): [2] (range 3): general error:  [2] "_SYS_BIC"."XYZ/proc": line 87 col 3 (at pos 3631): [2] (range 3): general error: temp index not exists:  [0] No error (please check lines: 332)

 

After commenting out the below section, it runs fine.

SELECT COUNT (1)

INTO x

FROM :deals;

 

Not sure what what the issue is.

 

Any pointers on this would be appreciated.

 

Thanks,

HANA SQL Script Variables - Wildcard?

I have created a SQL script calculation view that utilizes variables. When trying to test this CV (using data preview), it prompts me to input the values for the variables, however it forces me to input a value for every variable. There are test cases where I would want to leave one or more variable blank or use a wildcard, however neither * or % work for wildcard.

 

Is there any way to set the variable to optional or use a wildcard? They are all set as VARCHAR, selection type Single Value, and marking as Input Parameter.

 

Thanks,

How to filter data in a Cal View Dynamically? (without using i/p parameters or variables)

June 8, 2016, 8:07 am

Hi All,

 

I have a requirement wherein I have to slice the data set into 3 separate data sets i.e Current Year Data, Current Year -1Data and Current Year -2Data based on Current Year but then the user will not be providing any i/p parameter or variable from the query and there is no current year in the table on which I have created this cal view.

 

I have only a fiscal year.

 

Below is what I have tried and think:

 

1. In normal BW system you can always get your current year/date from sys-datum using an ABAP routine or code so is there any such field in HANA?

 

2. I have used a filter expression in my cal view on the fiscyear column of my cal view i.e addyears(FISCYEAR,-1) and addyears(FISCYEAR,-2) but this is not working

 

3. will it help if I join a time dimension table to my table in the cal view to get the current year? if yes, how will I filter this year dynamically.

 

 

appreciate if you can provider any thoughts..

 

 

PS : My source is BW

 

 

Kind Regards,

Ashwin.

Querying a dim's column in star join HANA view why result in entire view execution (PlanViz))

June 3, 2016, 8:28 am

We are at HANA SP11 and BO 4.1 SP3 patch 2 with webi connecting to relational universe (Hana biz layer) to HANA star join calc. views. View under questions has star join with fact surrounded by left join with dimension calc views.

 

I am just trying to get LOVs for a dimension column without reference to any other column like
select DISTINCT DimColumn1 from view


and this column is not calculated column (anyway why it should matter unless it refers fact or any other view)


Also note, this behavior happens irrespective of whether I query directly on HANA studio or through BO IDT


Query takes very long time for result and our report prompt screen becomes slow. When I see plan viz, it shows query is going to entire fact table etc which confuses me why its doing so ?? I have just queried one column from dimension in star join.

 

As a temporary mitigation, we are bringing dim calc. view in universe and creating LOVs. When we started using star join , we thought this will have benefit of star schema. However, we are  seeing none.

SAP support says  "oh we see your plan viz it's doing what it's supposed to do". and our discussion still going on.

 

So two questions :

1) Why do you think its behaving that way ? Is there anything we could be doing wrong - given its star join, left outer join fact and dim, querying only one non-calculated column from dim

2) From your experience, how do you guys achieve same i.e. creating LOVs from similar setup of BO-HANA through relational universe so that only dim column view gets invoked

 

Further Info:-

-- There is left outer join b/w Fact and Dim

-- Non of join column are calculated column

-- There is no design time filter on Dim view

Conversion character to integer

Hi all,

 

I'm building a Calculation View based on SQL Scripting. Within this Calculation View I try to use the CE-functions as much as possble.

One of the challenges is the conversion of a character field (containing numbers) to something like an integer.

 

So, is there a way of doing that within a Calculation View?

 

Using conversion functions the validation is always okay, but running the view always leads to errors (mentioning that the data type for a specific function is wrong).

 

Any ideas?

 

Thanks!

SQL Error : insufficient privilege: Not authorized at ptime/query.... HTTP Connection to HANA Analysis Office

June 9, 2016, 11:41 am
$

Hi,

 

We currently have two environments which I will summarize below.  After a HANA db upgrade from version 95 to version 102 all views which have descriptions added to an attribute now produce an error about authorizations.

 

Environment Overview:

Non Prod:

  • HANA DB version 102
  • SBOP 4.1 SP7
  • Office Analysis 2.2 Sp3.1
  • Lumira 1.30

Prod:

  • HANA DB version 95
  • SBOP 4.1 SP7
  • Office Analysis 1.4 SP7
  • Lumira 1.30

It is worth noting that when making the move to Analysis 2.x and upgrading your hana system, you no longer can use ODBC to connect to HANA.  We have our non prod environment configured to use HTTP connection with SAML SSO through SBOP.  This is working great with no problems. The issue we are facing is that any attribute in a view which has a description mapped to it fails with the error: Caught exception : exception 42111: SQL Error : insufficient privilege: Not authorized at ptime/query/checker/query_check.cc:3389 (42014)

If I connect to our non prod hana database using the odbc connection method and analysis 1.4 SP7 not issues or errors are thrown and the descirptions are displayed as normal.  If I switch to Analysis 2.2 SP3.1 and use the HTTP connection I get the authorization error which I noted above. .

I have done further testing and found Lumira 1.30 connects to non prod hana ( direct connect not HTTP) and works fine producing the attributes and descriptions with out error. Has anyone else encountered this error?  I have not found any SAP notes or blogs with this problem.  I do have a case open with SAP but currently no traction.

How to set order(sequence) of Columns in HANA Calc. View with Star Join?

Dear All,

 

I have a HANA Calculation View(Graphical) and it has a Star Join in it, and here comes the problem.

 

Because of the Star Join, I get two part in Semantics -> Details, one part for Local Columns, another for Shared Columns(get from Join with other tables). Now I don't know how to set the sequence of all these columns, I can set in each part, but I can't set sequence for all columns when they are not seen to be belonged to divided parts.

 

Say I have Columns L1, L2, L3 in Local, and S1, S2, S3 in Shared, what if I want to get the sequence of this View as L1, S1, L2, S2, L3, S3 ?

 

 

Thanks!

Hi,

 

we are new in using CDS and certainly directly on HANA.

 

Can anyone give us some help on how to make on to do a full text search (FUZZY)?

 

Up to now we use native SQL to do this, but we want to get rid of that.

 

So now we want: HANA-CDS to external view in ABAP and use this in Open SQL in ABAP.

I don't find any real hints in the documentation, that is why I ask it here.

 

Thanks for helping.

Error in XS Trace - Assertion authentication failed with reason: Subject of assertion has to be provided using NameID

While talking to our ADFS admin, he says that he suspects that we need to add mapping rules in the ADFS Relying Party Trust for this to work correctly. Anyone familiar with the error and the mapping rules required? I can't find any in the SAP Marketplace nor here in the SCN site so any help would be more than appreciated.

 

Thanks a lot.
