Hi

You are asking questions and we are answering the questions..

seems you have forgotten to reward them

Yes you can create a dynamic internal table see the following.

Dynamic internal table is internal table that we create on the fly with flexible column numbers.

For sample code, please look at this code tutorial. Hopefully it can help you

Hi,

data: dref type ref to data. 
field-symbols: <wa> type any, <comp> type any.
create data dref type (query_table). 
assign dref->* to <wa>.

hI,

REPORT ZCLUST1 .

• Example: how to create a dynamic internal table

• The dynamic internal table stucture

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 = 'program 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-field1 = ''19970814''.'. APPEND INCTABL.

INCTABL-LINE = 'dyntab-field1 = 1.'. APPEND INCTABL.

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

INCTABL-LINE = ' '. APPEND INCTABL.

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

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

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

• Create and run the dynamic program

INSERT REPORT 'zdynpro'(001) FROM INCTABL.

SUBMIT ZDYNPRO.

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.
