Below is a number of ABAP code snippets to demonstrate how to select data from SAP ZIS_FORM table and store it within an internal table, including using the newer @DATA inline declaration methods. It also shows you various ways to process this data using ABAP work area, inline declaration or field symbols including executing all the relevant CONVERSION_EXIT routines specific to ZIS_FORM.

Sometimes data within SAP is stored within the database table in a different format to what it is displayed to the user. These input/output conversation FM routines are what translates the data between the two formats.

There is also a full declaration of the ZIS_FORM table where each field has a char/string type for you to simply copy and paste. This allows you to use processing that is only available to these field types such as the CONCATENATE statement.

DATA: IT_ZIS_FORM TYPE STANDARD TABLE OF ZIS_FORM,
      WA_ZIS_FORM TYPE ZIS_FORM,
      GD_STR TYPE STRING.

DATA: lo_typedescr type REF TO cl_abap_typedescr.
DATA: lv_fieldname type fieldname.

FIELD-SYMBOLS: <FIELD> TYPE any.
FIELD-SYMBOLS: <ZIS_FORM> TYPE ZIS_FORM.


*Original SAP ECC Select statement 
SELECT *
*restrict ABAP select to first 10 rows
 UP TO 10 ROWS      
  FROM ZIS_FORM
  INTO TABLE IT_ZIS_FORM.

*Select data and declare internal table using  in-line method @DATA 
SELECT *
  FROM ZIS_FORM
  INTO TABLE @DATA(IT_ZIS_FORM2).

*You can also declare the header/work area using the  in-line DATA declaration method 
READ TABLE IT_ZIS_FORM INDEX 1 INTO DATA(WA_ZIS_FORM2).


*Latest ABAP cloud SELECT statement using the FIELDS syntax. But note to following the clean core principles you should not select directly from an SAP table 
* and should instead use a CDS view or create you own CDS and use that.
SELECT FROM ZIS_FORM
  FIELDS *
*  WHERE would go here
  INTO TABLE @DATA(IT_ZIS_FORM2).


*Demonstrate how to loop at an internal table and update values using a FIELD-SYMBOL
LOOP AT IT_ZIS_FORM ASSIGNING <ZIS_FORM>.

*To update a field value using a field symbol simply change the value via the field symbol pointer
<ZIS_FORM>-BUKRS = 1.
<ZIS_FORM>-VZSKZ = 1.
<ZIS_FORM>-KONTO = 1.
<ZIS_FORM>-WAERS = 1.
<ZIS_FORM>-ANRED = 1.

ENDLOOP.

LOOP AT IT_ZIS_FORM INTO WA_ZIS_FORM.
*Write horizonal line to screen report.
  WRITE:/ sy-uline.

*Write selected data to screen/report before conversion.
  WRITE:/ sy-vline,   WA_ZIS_FORM-LAND1, sy-vline,
  WA_ZIS_FORM-NAME1, sy-vline,
  WA_ZIS_FORM-NAME2, sy-vline,
  WA_ZIS_FORM-NAME3, sy-vline,
  WA_ZIS_FORM-NAME4, sy-vline,
  WA_ZIS_FORM-ORT01, sy-vline.
ENDLOOP.
   
*Add any further fields from structure WA_ZIS_FORM you want to display...

  WRITE:/ sy-uline.
* Aternatively use generic code to Write field values (and NAME) to screen report
  DO.
    ASSIGN COMPONENT sy-index OF STRUCTURE wa_ZIS_FORM TO <field>.
    IF sy-subrc <> 0. EXIT. ENDIF.
    WRITE:/ 'Field Value', <field>, sy-vline.
    gd_str = <field> .
    lo_typedescr ?= CL_ABAP_DATADESCR=>DESCRIBE_BY_DATA( <field> ).
    lv_fieldname = lo_typedescr->GET_RELATIVE_NAME( ).
    WRITE:/ 'Field Name', lv_fieldname.
  ENDDO.

  
*Redo loop but convert all fields from internal to out value  
LOOP AT IT_ZIS_FORM INTO WA_ZIS_FORM.


*Write horizonal line to screen report.
  WRITE:/ sy-uline.

*Convert all fields to display/output versions using conversion routines
  PERFORM convert_all_field_values CHANGING wa_EKKO.
