Hi,
These are the names I got ( below screenshot).My user ID is BEST by which I have logged it into ABAP which is not coming in this list. I have one more question here. I have just debugged my report and I can see my select query is getting failed. How can i find out the reasob for the same. i am not worried about the window information but it must show output. below is the query which is getting failed.

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

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 Figure Type of HANA View in ABAP?

Hi,
Is there a way in ABAP to find out (by looking up some table or calling an FM/method) the type of a HANA view? I have an ABAP system that has a HANA database. Views of different types (calculation, attribute, analytic) have been created in HANA. In my ABAP code, I have the name of the view from which I want to find out the type of the view. Any ideas?
Thanks,
Akshat

Hi Kumar,
why would you need to know at all?
Anyways, you would have to know the name of the corresponding HANA entity. That is displayed when you open the external view in the ABAP Development Tools in Eclipse.
Additionally, you would have to know to which HANA Transport Container the HANA view belongs, have a look at the HTC (in the ABAP Development Tools in Eclipse). There are two tabs "Overview" and "Content". On the "Content" tab, you can find a list including package, name, and the type information you are looking for.

Jasmin

HANA views call in ABAP ECC 6.0 via secondary connection

Dear Folks,
We have created views in HANA, same views we need to call it in ABAP ECC 6.0(Netweaver 7.3) i.e. via secondary database connection.
So,
1.Is it possible to call HANA vies in ABAP ECC 6.0?
2.Is there any version limitations? or will work fine on ECC 6.0
3. If yes can you give me sample code of abap to access hana as secondary database
Note : I have gone through Mr. Thomas Jung thread.
Regards,
Amol

Hi Amol,
so, ADBC is available in your system, but you have to make sure that the correct DBSL library for HANA (HDB) is available in your system. You can then just check if you can correctly communicate with the report ADBC_TEST_CONNECTION (using the secondary connection maintained in table DBCON) to your HANA database.
You may have a look at the example on how to select from an external view in report ADBC_QUERY (which selects from a DB table), by using a secondary DB connection to your HANA DB and using the HANA view instead of a DDIC table.
Of course in ADBC you have to take care about the correct type mapping (as you cannot use a DDIC type for definition of your internal table into which you select).
Best,
Jasmin
BTW: One word of precaution, the tasks you try to accomplish is rather cumbersome. We definitively recommend to use a more recent release (e.g. NetWeaver 7.4 SP5 or beyond), however, I think that's not your decision, right?

Creating Logic and modeling for SAP BW datasource in SAP HANA views and SLT

Hi to all,
I have small question.
We have BW system and SAP ECC as source system and to get data from SAP ECC source system we are using SAP ECC Standard data source.
Now we required to, create modeling in SAP HANA by use of HANA View and get data from SAP ECC source table via SLT.
So we can replicate same modeling,as we done in SAP BW system.
But my question is that, as SAP ECC standard data source hit multiple table and do run-time calculation, before sending to SAP BI.
How we can derives such calculation and logic, in our HANA studio, because as we know in SLT data transformation can be done in limited way also
in view we can not drive such logic via SQL script ?.
Is there any way we can do such modeling and logic in SAP HANA ?
or
is there any standard document for this type of case, which we can use ?
Note: We don't want to use SAP DS or DXC for data loading to HANA, as we want it in more real time.
Regards
Pavneet Rana

Thanks for reply,
As SLT is based on ABAP, so we can write complex logic in it.
But if we talk about SAP ECC standard data source, they have complex logic, based on multiple table.
So we need to write code from scratch in SLT to derive same result. but it will be huge time consuming , and required good ABAP skills, also it will lead to bug in code.
Also it will reduce the real time performance of SLT, due to complex logic.
Second option is procedure via SQL script, which is again huge effort in term if logic and can lead to error/bug in logic.
Does we have any other way or architecture to do this is very simple way, with high performance and less error issue.

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

How to Call HANA Procedure in ABAP

Hi Everyone,
I am new to ABAP
I have created a procedure in HANA that accepts two input parameters and outputs a table
I am using HANA as a Secondary Database
How can I call this procedure in my ABAP program?
Regards,
Vivek

Hi Vivek,
depends on how you would like to call it :-)
1. Use native SQL to call the procedure (see report ADBC_DEMO_PROC_CALLS_HDB; available in any system with a minimum NetWeaver release 7.40 SP5).
2. Create a DB Procedure Proxy and call the DB Procedure Proxy (Tutorial: How to consume SAP HANA Procedures in ABAP; only "directly" available if HANA is the primary DB underlying your system, for secondary DB system see discussion Execute Procedure with input parameters as table from ABAP).
3. (Method of choice available as of NetWeaver 7.4 SP5): Create an ABAP managed DB procedure (instead of the native HANA procedure) as described in ABAP Managed Database Procedures - Introduction
Cheers,
Jasmin

HANA views connection to Tibco Spotfire

Hello,
I am working with Tibco Spotfire version 6.5. I can consume tables in HANA system but I am unable to consume the HANA views. Can I connect to HANA views from the tool? If so, how do I? Thanks in advance!

Hello Praseedha -
Thanks for the quick response. It is interesting to know that you cannot embed the data from HANA views into Spotfire memory. It is my understanding that you can leverage both the options -> In database connection & In memory for databases like HANA.
Were you able to obtain the description of fields from HANA views instead of just the technical names when you inserted a HANA view into a table in Spotfire?
Looking forward to your response.

Sudheer B.

Authorization Issue while Data Preview from HANA View

Hi Experts,
We are using BW on HANA. We have created DSOs (info provider) in BW and generated HANA views from there. We have also created analysis authorizations in BW for authorization relevant characteristics. In HANA, we are able to go to the generated analytic view and preview the data from it successfully.
Now I have created a test user and assigned a custom role with below authorizations to this user in HANA:
- bw2hana/../REPORTING role (this role is automatically created by activation of DSO in BW).
- Roles MODELING, MONITORING, CONTENT_ADMIN, USER.
- Multiple system privileges although not needed, like REPO.EXPORT, REPO.IMPORT, etc.
- Analytic Privilege _SYS_BI_CP_ALL
- Package Privilege: REPO.READ for all required packages (tried with ROOT package also).
In BW system also, the test user has analysis authorizations providing access to the relevant info objects.
But when I am trying to preview data for HANA view, I am getting attached error (also listed below):
"Cannot get the data provider outline
SAP DBTech JDBC: [2048]: Column store error: Search table error: [2950] user is not authorized"
I tried to trace the situation is HANA and got below details in 2 trace files:

Do you know what this "Error during converting SqlAPs to Query entries" actually means"? How can we resolve this issue? The authorization is working properly for our user ids. But we need to provide restricted access for business users so trying to create test user and custom role.
Thanks
Nitesh Gupta

Hi Pinaki and Prabhith,
Yes, my issue was resolved. Sorry, missed to updated here.
I was just a beginer for BW on HANA Security at that time and didn't know many small things. The solution was pretty simple.
Whenever you assign analysis authorizations to a user in BW, you also need to generate corresponding HANA authorization. This is done through tcode RS2HANA_CHECK tcode. This tcode converts BW analysis authorizations into HANA analysis authorizations and assign to the HANA user. You can see generated HANA authorization table RS2HANA_AUTH_STR in both BW and HANA.
Once the HANA authorizations are successfully generated for a user, he should be able to see data from Views.
Let me know if this solves issues. Then I will close this thread.
Thanks

Trying to call HANA procedure via ABAP

Hi everyone,
I am using ABAP in Eclipse in order to call a HANA procedure within a BPC process chain. While referring to an SCN blog written by Baris Cekic, I have put together a working ABAP Class. This works as my proxy to a functioning HANA stored procedure. My issue is with the ABAP program I am using for the process chain. I believe that I'm passing my input parameter using the wrong format. Please bear with me, as I am not an ABAP programmer! Any help would be much appreciated! Please take a look at the screenshots. Thanks!
ABAP CLASS - ZCL_BPC_AMDP:
HANA PROCEDURE - ZPROC_BPC_AMDP:
ABAP PROGRAM - ZBW_BPC_AMDP:
This is my issue!! -----> INPUT of SP Name: (I've tried with and without the schema):
ABAP PROGRAM ERROR:

Hi Anand,
you should preferentially use "NVARCHAR" instead of the non-unicode derivate "VARCHAR". As ABAP supports both unicode and non-unicode systems, we only allow the mapping of Strings/character literals from ABAP to NVARCHAR variables in HANA in all ABAP on HANA systems.
Please find an example of a _SYS_BIC procedure in an AMDP in class CL_EPM_OIA_SIMP_BP_CLSF_AMDPDT (method AMDP_GET_BP_CLASSIFICATION). Should be available in your system.
And you can additionally try to execute the call you put into the AMDP directly in the HANA SQL console.
Cheers,
Jasmin

Windows authentification while consuming web service from ABAP

Hi All,
We are consuming web service from ABAP, we have created client proxy in SE80 and configured logical port in LPCONFIG.
This one was working fine. Now we have added windows user authentification to access this service.
Now when I'm trying to regenerate this proxy in R/3 it is asking for user and password. When I enter these details this one is not working.
If I access this service direcly from internet explorer and I enter same user and password then I would able to access this service.
Could you please let me know how to handle this.
Regards
Vikram

The dialog that is produced by HTTP Destination object of the logical port is designed only for use within Classic Dynpro applications. There is no prompt produced when running in Web Dynpro. If possible assign a generic user within the logical port definition and this will be used automatically by all users.
