Hi,

I have one more important question.

How ADBC connection is benefits by using SAP HANA as secondary database in terms of performance wise for the access of data from HANA database as a secondary database.

I have 2 options and which is better for the good performance for accessing the data-

1 .  In ABAP Reports in the SELECT statements by using CONNECTION (“HDB”) will this improve the
     performance.
      e.g : select * from BSEG into TABLE IT_TAB CONNECTION (“HDB”).

2. Will Create the Stored procedure in HANA studio and Call
   from ABAP as below by using NATIVE SQL–

     EXEC SQL

      SET CONNECTION (‘HDB’).

     ENDEXEC.

    EXEC SQL.

      EXECUTE PROCEDURE proc (IN    p_in1                       
                             OUT   p_out1   OUT   p_out2 )

   ENDEXEC.

Regards,
Pravin

Hi Experts,

I am using a CDS view with following join conditions.

And the where condition is " where  a.kdauf = :p_vbeln  or ( b.kdauf = :p_vbeln and b.werks = :p_werks ) or c.vbeln = :p_vbeln ".

Its taking at around 30 secs to execute. Is there any other way to make the cds view to work fast without hampering the functional requirement.

Thanks and regards

Hello All,

I have a file in application server and I read it line by line. There are predefined fields in the record which should be compared against values maintained in a custom table and if matches then should be updated in a z table. The file is huge and the logic already in place is consuming time and hence we are eying the possibility to do it through amdp. Can someone guide as to how to start with the same?

Example:

The file data is seperated by ;If the second value in the current record is either a,b,c,d(to be checked against the custom table) and if fourth data in the current record is either 1,2(check the table) then a custom table is to be updated.

Thanks,

Prem

Hi,

I have created a customized HANA View as per the requirement and fetched in Fiori. Now SAP says all the Calculation views to be converted to CDS Views.

• I got to know the procedure, First we need to convert Customized HANA View to External View and consume external view in CDS. I am very new to CDS  so please someone elaborate how to convert HANA View to external view and how to consume in CDS?

Thanks in Advance

Hello All,

I need to know is CDS view and Attribute view are co related and what is the difference between CDS view and Attribute view.

Please suggest.

Hi,

I need some reference or basic fundamental to start working on Eclipse using ABAP.

Please let me know if anybody can help in this.

Dear Expert,

Other then ABAP, can CDS (core data services) consumed by other reporting tools? e.g Bobj, Lumira or HANA modeling join with other hana view. I googled but can't find any.

Thank you.

Hi All,

Is it possible to consume the ABAP CDS view to other reporting tool i.e. analysis for office, lumira, Dashboard etc.

If yes, Can you please guide how to achieve it.

Many thanks in advance.

Hello,

We are using HANA as secondary database and I need to execute HANA Procedures from ABAP.

I have created a procedure in HANA with a parameter as input and table as output.

I executed it in HANA as

CALL "_SYS_BIC"."xxx/RETREIVE_ZHMARA"('MT02',?)

and it worked fine.

but I'm not able to execute it from ABAP.

My need is to pass parameter as input and get the result in a internal table.

Following is my code:-

DATA:  stmt_ref    TYPE REF TO cl_sql_statement,

        con_ref     TYPE REF TO cl_sql_connection,

        res_ref     TYPE REF TO cl_sql_result_set,

        d_ref       TYPE REF TO data,

        d_ref1      TYPE REF TO data,

        lv_mtart    TYPE zhmara-mtart,

        output      TYPE i.

lv_mtart = 'MT02'.

     con_ref = cl_sql_connection=>get_connection( 'ABC' ).

     stmt_ref = con_ref->create_statement( ).

GET REFERENCE OF lv_mtart INTO d_ref.

         stmt_ref->set_param( data_ref = d_ref

                              inout    = cl_sql_statement=>c_param_in ).

        stmt_ref->execute_procedure( proc_name =

                                '"_SYS_BIC"."xxx/RETREIVE_ZHMARA"' ).

GET REFERENCE OF lt_zhmara INTO d_ref1.

                                           res_ref->set_param_table( d_ref1 ).

* Get the complete result set in the internal table

         output = res_ref->next_package( ).

         LOOP AT lt_zhmara INTO ls_zhmara.

           WRITE : /, ls_zhmara-mandt,

                      ls_zhmara-matnr,

                      ls_zhmara-ersda,

                      ls_zhmara-ernam,

                      ls_zhmara-laeda,

                      ls_zhmara-mtart,

                      ls_zhmara-matkl,

                      ls_zhmara-meins.

         ENDLOOP.

This works fine till  stmt_ref->execute_procedure   , sy-subrc = 0.

but gives a dump later as  'res_ref' is not initialized hence has ZERO value.

How can I set this?

** set_param_table for output parameter is only available in class cl_sql_result_set  but what should be the reference for its object res_ref??

Kindly suggest...

Hi All,

I have to join CDHDR and CDPOS using cast function OBJECTID and kostl field which has different length.Is it possible to cast using join function in New abap open SQL.Please help.Thanks.

Hello,

I recently learned about calling HANA stored procedures from ABAP. As per the instructions, we are supposed to use the WITH OVERVIEW addition while calling the stored procedure. This would result in a name-value table (basically containing the output parameters of the stored procedure) using which as the basis, we need to write subsequent queries in order to get the data that we want. So, broadly speaking that's two main steps - the first where we write code to get the overview table and the second where we query based on the overview table.

I wonder if there is a shorter way of calling stored procedures, one that involves just one step where you are able to pass the information about which parameters' data you are looking for so that the single call returns you all the data. Is there such a way? Maybe one that involves NOT using the WITH OVERVIEW addition?

Thanks,

Akshat

Hello Gurus,

In the next future  I'll probably work in a project where it will been installed the DB  Hana .

I shall have to test all custom FI transactions , do you know what could be the error encountered ?

for example error in select statement and so no .

thanks in advance

Hi All,

I'v tested CDS with currency conversion versus the classical approach with the function module for currency converion on application layer (CONVERT_AMOUNT_TO_CURRENCY). The classical approach seemed to be much faster, so I started testing.

Please find attached the objects used for testin:

• y_cds_test_currconv.txt -> Simple ABAP report with both options
• Y_CDS_TEST_CURRCONV.txt -> The CDS view

I test on a system with AS ABAP 7.4 SP8 + HANA SP 8 and also AS ABAP 7.4 SP8 + HANA SP 9.

There's actually an OSS, but the it's refering to Oracle DB and not HANA DB (2067294).

Native SQL statment (tracing done with ST05)

SETSCHEMA"SAPMDE";

SELECT

   "CARRID",

   "CONNID",

   "FLDATE",

   "SOURCE_PRICE",

   "SOURCE_CURRENCY",

   "TARGET_AMOUNT",

   "TARGET_CURRENCY"

  FROM

    "YTESTCUR" ( "TO_CURRENCY" => 'EUR' ,

                              "EXC_DATE" => '20150427' ) "YTESTCUR"

  WHERE

    "MANDT" = '100'

Result

Change the CDS and replace the CURRENCY_CONVERSOIN by table field PRICE. (to check if the slow performance is cause by the currency conversion function)

Result run native SQL statement:

I have also run the SAP HANA Plan Visualizer, refer the next screenshots.

It seems to me that the currency conversion has some performance issue. Has anybody experienced the same and maybe found a solution?

One final remark: for testing you need to have data in FLIGHT model. (Go to SE38 and run SAPBC_DATA_GENERATOR to generate data)

Thanks in advance.

Best Regards,

Bart

Hi All,

Currency_conversion function in CDS view  terribly decrease performance of the cds  view,  view running in few seconds run for minutes after adding currency_conversion function. I am working on 7.40 SP10 system.

- I could not find any note for the issue for my system's support pack level ( I will open one )

- I tried to select  conversion ratio from tcurr table but it is necessary to subtract gdatu date from 9999999 to get actual date and could not cast gdatu to numeric field to  be able to perform necessary arithmetic operation in cds view. 

- Last solution I have in mind but  trying to avoid  is creating ZCURR table with proper date field instead of gdatu and filling it for the past and recent currency values using a simple program and daily job.

Do you have any other solution for above problem ? I searched the forum but find only one post for the issue which does not suggest any solution 

Hello,

Hello,

I have downloaded and installed Netweaver ABAP trial 7.3 some time ago and Im learning ABAP with book ABAP learning course by Karl-Heinz Kuhnhauser.

And during my learning Im thinking about my future career path in SAP. I find fastinating SAP HANA platform. Do you think this platform will be really huge in the future and more customers will want this alternative to SAP ERP etc. ?

And since ABAP knowledge is not a requirement for learning SAP HANA, what is? I researched it should be other languages such as SQL, SQLScript or javaScript, are there any others?Do you think I should continuing with learning ABAP and concurrently start to learn also other language for SAP HANA?

I would be truly grateful for your opinions and advices.

Thank you, Tereza

Dear all

I have a question regarding the use of a variable in an ABAP Managed Database Procedure.

The following method I implemented into a class:

How can I now insert a variable for the string 'YES' ?

I tried declaring a constant:

But I cannot use

... WHERE a.giftsyesorno = lc_yes;

Is there a solution for this problem? I would really like to use variables in the SQL syntax in the method.

Best regards

Thomas Bretonnet

Hello All,

Is it possible to make an odata service generated by the abap cds view CRUD enabled?

So can I do an UPDATE, DELETE, CREATE on the odata service?

I am reading stuff about BOPF ? Is this the way to go forward?

Regards,

Bert
