ABAP CDS views - SQL trace

April 20, 2016, 3:32 pm
$

Hi,

We have plans to write ABAP CDS views to standardize business logic/data extraction so that development team can make simple queries on CDS views. So we are writing generic CDS views means without many "WHERE" conditions.

I'm trying to understand how it works and impact on the performance when these CDS views are consumed for any particular Plant or Company code.

 

Let us  say I have below CDS view called "ZCDSV_TEST"

select * from vbak inner join vbap on vbak.vbeln = vbap.vbeln  { <fields> }.

 

I would like to understand when it is consumed in 2 ways in terms of performance (SQL)

Select * from ZCDSV_TEST  <<<<  1M records

Select * from ZCDSV_TEST WHERE Vkorg = '0001'  <<<< 25K records.( Does this extract 1M records first and then apply WHERE condition to get to 25K.

 

Would like to understand these type of technical details. Appreciate your inputs.

 

Cheers.

Table name with special character '/' in from clause of select query of AMDP procedure.

Hi All,

 

I have created AMDP procedure and trying to consume in AMDP class which is implementing  the required AMDP interface and everything is working fine, but  in my procedure i am trying to use one table name (which has special character '/' in it) which is giving an error.

 

Please find my procedure as follows:

 

      METHOD my_hana_procedure by database procedure

      for hdb

      language sqlscript

      options read-only.

      using /CPD/D_PFP_TEST.

 

               table = select  * from  /CPD/D_PFP_TEST;  /*------ Here i will get an error saying SQL SCRIPT : &a0&a1&a3&a4.......&a9   */


     ENDMETHOD.

 

Note: The above mentioned table /CPD/D_PFP_TEST is in system SID schema.

FYI, If i am using any table which do not contains special character '/' in it will work without any error.

 

Did anyone faced the same issue?, at least here error information should be meaning full we can correct our errors inside AMDP procedures.

 

Thanks in advance,

Problems on CDS Views performance

Hi Guys,

 

I'm having problems with CDS View now, I have a table ACDOCA which has 400 million rows, and in the CDS View(say CDS View Main),  ACDOCA(only some fields are used) is used to join 3 other tables.

And I found in PlanViz that all 400 million rows are used to do the join, it consumes a log memory and VERY SLOW.

 

I write a CDS view(CDS View Agg) in which I select the used fields from ACDOCA and do the aggregation, the result is about 1 million rows, then I use CDS View Agg in CDS View Main to replace ACDOCA.

 

I thought this should solve the performance problem, but it didn't. In PlanViz I still see 400 million in join.

 

Please help how to avoid doing such weird thing, I don't think there's any benifit in it.

 

Regards,

Hello,

 

I'm using the new ALV 'cl_salv_gui_table_ida' combined with a Core Data Service. I've activated the toolbar text search and enabled the search for a plenty of columns:

 

    go_alv_display->field_catalog( )->enable_text_search( 'NAME1' ).

    go_alv_display->field_catalog( )->enable_text_search( 'ORT01' ).

    go_alv_display->field_catalog( )->enable_text_search( 'PSTLZ' ).

    go_alv_display->field_catalog( )->enable_text_search( 'INFNR' ).

    go_alv_display->field_catalog( )->enable_text_search( 'LIFNR' ).

    go_alv_display->field_catalog( )->enable_text_search( 'LIFNR_2' ).

    go_alv_display->field_catalog( )->enable_text_search( 'MAKTX' ).

    go_alv_display->field_catalog( )->enable_text_search( 'SMTP_ADDR' ).

    go_alv_display->field_catalog( )->enable_text_search( 'ORT02' ).

 

The search is working for the fields NAME01, ORT01, PSTLZ, MAKTX, ORT02, The other columns don't work in the search.

 

I've checked the coding and found out that the search_scope is just filled with the working columns.

 

Class: CL_SADL_ABQI

Method: _GET_SEARCH_SCOPE

 

But I couldn't find the coding where the scope is filled.

 

Thx for your help!

             where S_FRES = r1.S_FRES;

            

       end for;

end;     

 

 

ENDMETHOD.

 

instead of importing temporary table if i use any other table like SFLIGHT i will not get any error.

Is there any restriction that we cannot use update for temporary table (lt_temp_tab) as explained above in procedure in AMDP procedure?

Please suggest me here .

Hi all,

 

Is internal table processing faster in AMDP?

 

Context :

We have abap code which is currently taking up ~80% of execution time.

When analyzed we see it's all looping into internal tables in abap.  Calculating and updating the same internal tables.

Is it a good idea to do these calculations in AMDP ? Will that give us any benifit ? i doubt...

Type mismatch in AMDP with Fuzzy Search

May 11, 2016, 3:23 am

HI,

 

I am implementing a full text search using AMDP and I want to return also the result of the HIGHLIGHTED function.

But I always get a type-missmatch between the result of the function, and the definition of the output of my AMDP-class.

 

This is the definition of the outpup-structure:

      BEGIN OF ty_struc,

        score         TYPE za_hana_score6_5,

        text          TYPE /bobf/text_content,

        snippet      TYPE string,

        highlighted   TYPE string, " /bobf/text_content,

        host_key      TYPE /bobf/conf_key,

        text_type     TYPE za_bopf_text_type,

        text_subtype  TYPE za_bopf_text_subtype,

        language_code TYPE spras,

      END OF ty_struc,

 

And this is the SELECT-statement:

    rt_table = SELECT

         score() as score,

         content.text ,

         SNIPPETS (text) as snippet,

         highlighted (text) as highlighted,

         collect.host_key,

         hdr.text_type,

         hdr.text_subtype,

         hdr.language_code

 

This is the error I get:

 

return type mismatch: Type "79"  of attribute "HIGHLIGHTED not compatible to type "56"  of attribute "HIGHLIGHTED"

 

where "56" is the definition out of the SELECT.

The SNIPPET works perfectly ...

The original type ( /bobf/text_content ) is also a string.

 

Has anyone any idea how I should define the highlighted-field in the output structure of my class, to avoid this mismatch.

Kind Regards.

Using OData custom query options (URL parameters) in Gateway

November 12, 2015, 9:03 am

Hi,

 

I created a CDS view with explicitly defined parameters and generated a Gateway OData service on top using SADL. Now I want to use OData custom query options to map them to the CDS parameters. I'm quite sure that this will not work automatically.


I'm already able to set the CDS parameters in the OData service DPC_EXT class manually, using the method if_sadl_gw_query_control~set_query_options.


METHOD if_sadl_gw_query_control~set_query_options.

     IF ( iv_entity_set = 'POIPARAMSet' ).

          IF sy-subrc = 0.

               io_query_options->set_entity_parameters(

                    it_parameters = VALUE #( (

                         entity_alias = 'POIPARAMSet' parameters = VALUE #( (

                              name = 'P_PurchaseOrderNetAmount' value = '10'

                         ) )

                    ) )

                )

          ENDIF.

     ENDIF.

ENDMETHOD.

 

However, I want to use custom query options (URL parameters) and want to map them to CDS parameters within the DPC_EXT class.

 

The URL looks like:

...ZBF_POIPARAM02MAN_SRV/POIPARAMSet?P_Material='STANDARD'

 

Unfortunately, these custom query options are obviously not parsed by Gateway. I can't find them anywhere in the data structures of MR_REQUEST_DETAILS or MO_CONTEXT. Fields like PARAMETERS, MT_PARAMETERS or URI_PARAMETERS are empty or containing other stuff. The custom query options only appear in the ~request_uri header parameter in a non-parsed way like

 

....?param1=1&param2=2&param3=3....  [figure01]

 

Of course I can parse the query string myself but I believe there must be an other way to access them. However, I also read in a SCN post from 2012, that SAP doesn't support this aspect of the OData standard. Is this still true?

 

>> Query parameters in CRUD operations

 

Kind regards, Tobias
