Increment variable dynamically in LOOP

Former Member — Sun, 01 Mar 2009 07:48:47 GMT

Hi All,

I have a situation where I have to loop at a table and fill an internal table while incrementing the variable name of the internal table at the same time.

For instance I have three variables: var1, var2 and var3. In the first loop I want to assign the value to Var1, in the 2nd loop to var2 and in the third loop to var3 and so on.

types: Begin of t_second

var1 TYPE C,

var2 TYPE C,

var3 TYPE C,

end of t_second.

data : gt_second type table of t_second,

wa_second type t_second.

LOOP at gt_first into wa_first.

MOVE: wa_first-var TO wa_second-var1, <---- in the 2nd loop I want to make this var1 to var2 and so on.

APPEND wa_first TO gt_second

CLEAR wa_first

ENDLOOP.

Will it be possible to achieve this with ABAP?

Thanks.

USE:

PERFORM: sy-tabix OF sub1 sub2 sub3.

as the value of sy-tabix increases value subroutine will be executed.

Ex:

When SY-tabix = 1--->SUB1

When 2----->SUB2

TYPES: BEGIN OF t_second,
var1 TYPE c,
var2 TYPE c,
var3 TYPE c,
END OF t_second.

DATA : gt_second TYPE TABLE OF t_second,
wa_second TYPE t_second,
wa_first(20) TYPE c,
gt_first TYPE TABLE OF t_second.

wa_first = 'TEST'.
append wa_first to gt_first.

wa_first = 'TEST'.
append wa_first to gt_first.

wa_first = 'TEST'.
append wa_first to gt_first.
LOOP AT gt_first INTO wa_first.

  PERFORM: sy-tabix OF sub1 sub2 sub3.

*   MOVE: wa_first TO wa_second-var1.  " <---- in the 2nd loop i want to make this var1 to var2 and so on.

  APPEND wa_first TO gt_second.
  CLEAR wa_first.
ENDLOOP.

*&---------------------------------------------------------------------*
*&      Form  sub1
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
FORM sub1.

  MOVE: wa_first TO wa_second-var1.
ENDFORM.                                                    "sub1

*&---------------------------------------------------------------------*
*&      Form  sub2
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
FORM sub2.
  MOVE: wa_first TO wa_second-var2.
ENDFORM.                                                    "sub2

*&---------------------------------------------------------------------*
*&      Form  sub3
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
FORM sub3.
  MOVE: wa_first TO wa_second-var3.
ENDFORM.                                                    "sub3

Hello,

you can use case endcase statement.

LOOP at gt_first into wa_first.

CASE sy-tabix.

when 1.

MOVE: wa_first-var TO wa_second-var1.

when 2.

MOVE: wa_first-var TO wa_second-var2.

when 3.

MOVE: wa_first-var TO wa_second-var3.

when others.

message for no variable to transfer data

endcase.

APPEND wa_first TO gt_second.

CLEAR wa_first.

endloop.

use field symbols

Hi,

I understood your Requirement. I am giving you one dynamic Solution. This is applicable in all cases. Like Uploading data from Excel, or Building Dynamic fieldcats.

Illustration:

data: Begin of wa1,

var type char10, " (take any length you want)

end of wa1,

itab1 like standard table of wa1.

data: begin of wa2,

var1 type char6,

var2 type char7,

var3 type char8,

var4 type char9,

var5 type char10,

end of wa2,

itab2 like standard table of wa2.

field-symbols: <FS1> type any.

parameters: p_a RADIOBUTTON GROUP gr1 default 'X', " fill in diagonal

p_b RADIOBUTTON GROUP gr1. " fill in left triangle

start-of-selection.

wa1-var = 'Balaji'. Append wa1 to itab1.

wa1-var = 'Balaji1'. Append wa1 to itab1.

wa1-var = 'Balaji12'. Append wa1 to itab1.

wa1-var = 'Balaji123'. Append wa1 to itab1.

wa1-var = 'Balaji1234'. Append wa1 to itab1.

loop at itab1 into wa1.

assign component sy-tabix of structure wa2 to <FS1>.

if sy-subrc = 0.

<fs1> = wa1-var.

append wa2 to itab2.

unassign <fs1>.

if p_b is INITIAL.

clear: wa2.

endif.

else.

exit.

endif.

endloop.

Try this one.

Thank you,

Balaji Peethani.

Hello,

This is the sample code:

data variable type char5.

data no type char2.

data vartab type table of char5 with header line.

do 5 times.

pack sy-tabix to no.

concatenate 'Var' no into variable.

append variable to vartab.

enddo.

loop at vartab.

write: / vartab.

endloop.

Hope this helps you.

Thank,

Augustin.

I hope you adopt one of the last three solutions. The others are nice efforts, but not right.

Hi mark,

kindly chk the followingg code , it works according to the requirement.


types: Begin of t_second,
var1 TYPE C,
var2 TYPE C,
var3 TYPE C,
end of t_second.

data : gt_second type table of t_second,
wa_second type t_second.

types: begin of t_first,
  var type c,
  end of t_first.

  data: gt_first type table of t_first,
        wa_first type t_first.

data: w_idx type i value 1.

do 9 times.
  wa_first-var = sy-index.
  append wa_first to gt_first.
  enddo.
LOOP at gt_first into wa_first.
  case w_idx.
    when 1.
      CLEAR wa_second.
      MOVE: wa_first-var TO wa_second-var1.
      APPEND wa_second TO gt_second.
      w_idx = 2.
     when 2.
       CLEAR wa_second.
       MOVE: wa_first-var TO wa_second-var2.
       APPEND wa_second TO gt_second.
       w_idx = 3.
      when 3.
        CLEAR wa_second.
        MOVE: wa_first-var TO wa_second-var3.
        APPEND wa_second TO gt_second.
        w_idx = 1.
  ENDCASE    .
ENDLOOP.

loop at gt_second into wa_second.
  write:/ wa_second-var1,
           wa_second-var2,
            wa_second-var3.
endloop.
