How does Select-Options from multiple tables work in CDS VIEW context?

[Former Member]

Hello,

i basically ask my question in the subject title. I am pretty new to ABAP and programming in general. I created a program which joined some tables together and u can refine your search via select options.

*& Selectionsbildschirm
SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE TEXT-001.
SELECTION-SCREEN SKIP.
SELECT-OPTIONS: bsart FOR ls_ekko-bsart,
                ebeln FOR ls_ekko-ebeln,
                ekgrp FOR ls_ekko-ekgrp,
                banfn FOR ls_ekpo-banfn,
                werks FOR ls_ekpo-werks OBLIGATORY DEFAULT '0001' TO '0004'.
SELECTION-SCREEN END OF BLOCK b1.

SKIP.

PARAMETERS: layout LIKE disvariant-variant DEFAULT '/B'.

... later in the code I have the select statement, where i select my tables, and also the join conditions and after that this comes:

So when I was correct, this is how a select-option possibility can look like. Now I am trying to implement a CDS VIEW instead. I tried some things that I get from the internet but I have basically no idea how a select option can be implemented. Have it to be in the DDL Source?

@AbapCatalog.sqlViewName:'Z_PSP_CDS'
@AbapCatalog.compiler.compareFilter: true
@AccessControl.authorizationCheck: #CHECK 
@EndUserText.label: 'CDS_VIEW_PSP'
@VDM.viewType: #BASIC
@Analytics.dataExtraction.enabled: true



define view Z_PSP 
    as select from ekko as a left outer 

    join ekkn as b 
    on b.ebeln = a.ebeln   

    join ekpo as c 
    on a.ebeln = c.ebeln
    
    join zs1ek_banf_tools as d
    on d.banfn = c.banfn   

    join user_addr as e
    on e.bname = d.aussteller
      {
    a.bsart,
    a.aedat,
    a.ebeln,
    a.ekgrp,
    b.ebelp,
    b.sakto,
    b.ps_psp_pnr,
    c.banfn,
    c.matnr,
    c.txz01,
    c.werks,
    d.aussteller,
    d.gettyp,
    d.kunde,
    e.name_last
    }
//     where a.bsart = bsart
//       and a.ebeln = a.ebeln
//       and a.ekgrp = ekgrp
//       and c.banfn = c.banfn

or in the report somewehre itself?

**1... Declare SELECT-OPIONS
SELECT-OPTIONS: bsart FOR ekko-bsart,
                ebeln FOR ekko-ebeln,
                banfn FOR ekpo-banfn.
START-OF-SELECTION.

*2... Create object reference ALV with IDA
 DATA(lo_alv_display) = cl_salv_gui_table_ida=>create( iv_table_name = 'EKKO' ).

*3... Build range tables
DATA(lo_range_collector) = NEW cl_salv_range_tab_collector( ).

lo_range_collector->add_ranges_for_name( iv_name = 'BSART'

                                         it_ranges = bsart[] ).

lo_range_collector->add_ranges_for_name( iv_name = 'EBELN'

                                         it_ranges = ebeln[] ).
                                      
lo_range_collector->add_ranges_for_name( iv_name = 'BANFN'

                                         it_ranges = banfn[] ).                                         

lo_range_collector->get_collected_ranges(
                    IMPORTING
                       et_named_ranges = DATA(lt_select_options) ).

*4... Set select options

lo_alv_display->set_select_options( it_ranges = lt_select_options ).


*5... Display ALV
*lo_alv_display->fullscreen( )->display( ).
cl_salv_gui_table_ida=>create_for_cds_view( 'Z_PSP' )->fullscreen( )->display( ).

I have zero clue what and how I should do. Any advice would be appreciated

You cannot use select options in CDS directly.

You can use select options in the WHERE condition of Open SQL when reading from CDS entities.

I find a problem with this code because this can not use the select options here:

cl_salv_gui_table_ida=>create_for_cds_view( 'Z_PSP' )->fullscreen( )->display( ).="<-wrong code

the code will print the ALV from the CDS but no through the select options, why? because it's not used properly the object in the declaration,

*2... Create object reference ALV with IDA
 DATA(lo_alv_display) = cl_salv_gui_table_ida=>create( iv_table_name = 'EKKO' ).

Then we will have to call the class object with the method that prints the data using the select options and it would be like this.

lo_alv_display=>create_for_cds_view( 'Z_PSP' )->fullscreen( )->display( ). <-- rigth code

I hope this can help everyone.

Yes, You can use select options in CDS directly.
