Appending dynamic Internal table

kiran_k8 — Wed, 09 Feb 2011 09:54:17 GMT

Hi.

I am trying to create dynamic internal tables which can store data and can be used for

further processing in the program.Say,I have 4 ztable names maintained in TVRAVC table then

I should be able to create 4 internal tables which can store data and can be used for

further processing like looping,read etc.


field-symbols:<table> type standard table,
              <fs_t> type any.
 
data:     lr_data type ref to data,

*Creating dynmaic internal tables for further processing
data:g_var1(4) type c value 'itab_',
     g_var2(7) type c.
loop at g_t_rec assigning <fs_t>.
clear:g_t_tvarvc,g_source.
read table g_t_tvarvc with key name = c_tty1
                               low  = <fs_t>+0(2).
if sy-subrc = 0.
g_source  = g_t_tvarvc-low                            "KK
g_tabname = g_t_tvarvc-high.                          "ZTABLE1
concatenate g_var1 g_source into g_var2               "here i will get itab_KK
create data lr_data  type table of (g_tabname).  
assign lr_data->* to <table>.                         "here I got the Ztable structure
endif.
endloop.

How to get the internal table as ITAB_KK into which I can move the g_t_rec internal table data.Similary I intend to get 4 internal tables.Kindly let me know.

Thanks,

KIran

Hi,

Get field list of fields in main internal table G_T_REC and ITAB_* using methods of class cl_abap_structdescr and compare the field names of each and move the values from g_t_rec to itab_*.

(refer: - Jerry Coleman)

l_t_compdescr1  = l_r_structdescr->components. " of g_t_rec
 l_t_compdescr2  = l_r_structdescr->components. " of itab_kk

LOOP AG g_t_rec.
  LOOP AT l_t_compdescr1 
    READ TABLE l_t_compdescr2 WITH KEY name = l_t_compdescr1-name
    IF success.
      itab_kk-(l_t_compdescr1-name) = g_t_rec-(l_t_compdescr1-name).
      .....
      APPEND itab_kk.
    ENDIIF.
  ENDLOOP.
ENDLOOP.

Hope you got my point.

Hi,

The steps you performed can create the dynamic tables

for further processing like loop at or read table try using assign component


*got data from TVARVC into IT_TVARVC
create d_tab type table of (IT_TVARVC-HIGH).      "suppose HIGH have table name
create d_wa type (IT_TVARVC-HIGH).
assign d_tab->* to <ftab>.
select * from (IT_TVARVC-HIGH) into table <ftab>
        where (condn).                             "dynamic condn
loop at <ftab> assiging <fwa>.
assign component sy-tabix  of structure <ftab> to <fld>.   "assigning values to fields
endloop.
* same for read stat
read table <ftab> assiging <fwa>.

Thanks,

Anmol.
