Regarding Dynamic Internal Table Generation

[amit_khare]

Converting the row values of the internal table to the header or say column of one more internal table.

E.g begin of i_tab occurs 0,

field(10)

end of i_tab.

i_tab-field = 'matnr'.

append i_tab.

i_tab-field = 'meins'.

append i_tab.

Now the new internal table should hold the columns as matnr and meins it should look like

begin of i_tab1 occurs 0,

matnr

meins

end of i_tab1.

As I am working for 4.5 we dont have support for declaring statements like REFERENCE TO DATA.

Points will be rewarded definetely.

Thanks

HI Amit

try like this

DATA: BEGIN OF STRUCT OCCURS 10,

FILDNAME(8) TYPE C,

ABPTYPE TYPE C,

LENGTH TYPE I,

END OF STRUCT.

• The dynamic program source table

DATA: BEGIN OF INCTABL OCCURS 10,

LINE(72),

END OF INCTABL.

DATA: LNG TYPE I, TYPESRTING(6).

• Sample dynamic internal table stucture

STRUCT-FILDNAME = 'field1'. STRUCT-ABPTYPE = 'c'. STRUCT-LENGTH = '6'.

APPEND STRUCT. CLEAR STRUCT.

STRUCT-FILDNAME = 'field2'. STRUCT-ABPTYPE = 'd'.

APPEND STRUCT. CLEAR STRUCT.

STRUCT-FILDNAME = 'field3'. STRUCT-ABPTYPE = 'i'.

APPEND STRUCT. CLEAR STRUCT.

• Create the dynamic internal table definition in the dyn. program

INCTABL-LINE = 'report zdynpro.'. APPEND INCTABL.

INCTABL-LINE = 'data: begin of dyntab occurs 10,'. APPEND INCTABL.

LOOP AT STRUCT.

INCTABL-LINE = STRUCT-FILDNAME.

LNG = STRLEN( STRUCT-FILDNAME ).

IF NOT STRUCT-LENGTH IS INITIAL .

TYPESRTING(1) = '('.

TYPESRTING+1 = STRUCT-LENGTH.

TYPESRTING+5 = ')'.

CONDENSE TYPESRTING NO-GAPS.

INCTABL-LINE+LNG = TYPESRTING.

ENDIF.

INCTABL-LINE+15 = 'type '.

INCTABL-LINE+21 = STRUCT-ABPTYPE.

INCTABL-LINE+22 = ','.

APPEND INCTABL.

ENDLOOP.

INCTABL-LINE = 'end of dyntab. '.

APPEND INCTABL.

• Create the code processes the dynamic internal table

INCTABL-LINE = ' '. APPEND INCTABL.

INCTABL-LINE = 'dyntab-field1 = ''aaaaaa''.'. APPEND INCTABL.

INCTABL-LINE = 'dyntab-field2 = ''19970814''.'. APPEND INCTABL.

INCTABL-LINE = 'dyntab-field3 = 1.'. APPEND INCTABL.

INCTABL-LINE = 'append dyntab.'. APPEND INCTABL.

INCTABL-LINE = ' '. APPEND INCTABL.

INCTABL-LINE = 'loop at dyntab.'. APPEND INCTABL.

INCTABL-LINE = 'write: / dyntab-field1.'. APPEND INCTABL.

INCTABL-LINE = 'write: / dyntab-field2.'. APPEND INCTABL.

INCTABL-LINE = 'write: / dyntab-field3.'. APPEND INCTABL.

INCTABL-LINE = 'endloop.'. APPEND INCTABL.

• Create and run the dynamic program

INSERT REPORT 'zdynpro'(001) FROM INCTABL.

SUBMIT ZDYNPRO.

*create the fieldcatalog like this

loop at i_tab.

wa_fieldcatalog-fieldname = i_tab-field.

APPEND wa_fieldcatalog TO it_fieldcatalog.

CLEAR :wa_fieldcatalog.

endloop.

FIELD-SYMBOLS : <it_final> TYPE STANDARD TABLE,

<wa_final> TYPE ANY,

<w_field> TYPE ANY.

*******CREATE DYNAMIC TABLE***********************

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = it_fieldcatalog

IMPORTING

ep_table = new_table

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2.

IF sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

ASSIGN new_table->* TO <it_final>.

[amit_khare]

We dont have that class used here.And this class also uses a variable REF To Data.

Kindly suggest me something which is possible in 4.5 B

HI Amit

then you can try the sample code i have given. in that give the field name in the STRUCT internal table

hi amit while building fieldcat build like this

LS_FIELDCAT-FIELDNAME = FIELDNAME

LS_FIELDCAT-SELTEXT_L = SELTEXT.

****wHEN U WANT VALUE AS HEADING*******

LOOP AT ITAB.

LS_FIELDCAT-FIELDNAME = ITAB-FIELD.

LS_FIELDCAT-SELTEXT_L = ITAB-FIELD.

ENDLOOP.

BY THE ABOVE, VALUE OF THE INTERNAL TABLE WILL BECOME THE HEADING.

HOPE THIS SOLVES UR PROBLEM.

or Just try out this simpler dynamic internal tables

DATA: itab TYPE STANDARD TABLE OF spfli,

wa LIKE LINE OF itab.

DATA: line(72) TYPE c,

list LIKE TABLE OF line(72).

START-OF-SELECTION.

*line = ' CITYFROM CITYTO '.

line = ' AIRPTO '.

APPEND line TO list.

SELECT DISTINCT (list)

INTO CORRESPONDING FIELDS OF TABLE itab

FROM spfli.

IF sy-subrc EQ 0.

LOOP AT itab INTO wa.

• WRITE: / wa-cityfrom, wa-cityto.

WRITE 😕 wa-airpto.

ENDLOOP.

ENDIF.
