Dynamic Internal table problem

Former Member — Thu, 01 Jun 2006 10:14:36 GMT

Hi all,

I created program for creating dynamic internal table as below :

type-pools : abap.

field-symbols: <dyn_table> type standard table,

<dyn_wa>,

<dyn_field>.

data: dy_table type ref to data,

dy_line type ref to data,

xfc type lvc_s_fcat,

ifc type lvc_t_fcat.

selection-screen begin of block b1 with frame.

parameters: p_table(30) type c default 'T001'.

selection-screen end of block b1.

start-of-selection.

perform get_structure.

perform create_dynamic_itab.

perform get_data.
perform write_out.

form get_structure.

data : idetails type abap_compdescr_tab,

xdetails type abap_compdescr.

data : ref_table_des type ref to cl_abap_structdescr.

xfc-fieldname = 'LIFNR'.

xfc-datatype = 'C'.

xfc-inttype = 'C'.

xfc-intlen = '10'.

xfc-decimals = '0'.

append xfc to ifc.

xfc-fieldname = 'EBELN'.

xfc-datatype = 'C'.

xfc-inttype = 'C'.

xfc-intlen = '10'.

xfc-decimals = '0'.

append xfc to ifc.

xfc-fieldname = 'MATKL'.

xfc-datatype = 'C'.

xfc-inttype = 'C'.

xfc-intlen = '9'.

xfc-decimals = '0'.

append xfc to ifc.

xfc-fieldname = 'WERKS'.

xfc-datatype = 'C'.

xfc-inttype = 'C'.

xfc-intlen = '4'.

xfc-decimals = '0'.

append xfc to ifc.

xfc-fieldname = 'MATNR'.

xfc-datatype = 'C'.

xfc-inttype = 'C'.

xfc-intlen = '18'.

xfc-decimals = '0'.

append xfc to ifc.

xfc-fieldname = 'MAKTX'.

xfc-datatype = 'C'.

xfc-inttype = 'C'.

xfc-intlen = '40'.

xfc-decimals = '0'.

append xfc to ifc.

endform.

form create_dynamic_itab.

Create dynamic internal table and assign to FS

call method cl_alv_table_create=>create_dynamic_table

exporting

it_fieldcatalog = ifc

importing

ep_table = dy_table.

assign dy_table->* to <dyn_table>.

Create dynamic work area and assign to FS

create data dy_line like line of <dyn_table>.

assign dy_line->* to <dyn_wa>.

endform.

form get_data.

Select Data from table.

select * into table <dyn_table>

from (p_table).

endform.

form write_out.

Write out data from table.

loop at <dyn_table> into <dyn_wa>.

do.

assign component sy-index

of structure <dyn_wa> to <dyn_field>.

if sy-subrc <> 0.

exit.

endif.

if sy-index = 1.

write:/ <dyn_field>.

else.

write: <dyn_field>.

endif.

enddo.

endloop.

endform.

The problem now that I am unable to access the fields of internal table as as "<dyn_table>-lifnr" nor the work area as "<dyn_wa>-lifnr" .It says structure does not have the field.

Its also not accessible in the debug mode.

How do I access the field to populate data to the table?

Pls post ur ideas.

Thanks,

You can only use the field symbol (just as you're doing) but use the field name instead of the number:

assign component 'LIFNR'

of structure <dyn_wa> to <dyn_field>.

Hi,

FIELD-SYMBOLS : <FS_ANY> TYPE ANY.

ASSIGN COMPONENT 'LIFNR' OF STRUCTURE <dyn_table> TO <FS_ANY>.

Now <FS_ANY> will have the value of <DYN_TABLE>-LIFNR.

Hi,

I do I write a statement like

<dyn_table>-lifnr = 1000010452.

<dyn_table>-matnr = v_matnr....

append <dyn_table>.

and so on ?

It does not accept the value for the internal table <dyn_table>.

Thanks,

Do like this

FIELD-SYMBOLS : <FS_ANY> TYPE ANY.

ASSIGN COMPONENT 'LIFNR' OF STRUCTURE <dyn_table> TO <FS_ANY>.

<FS_ANY> = 1000010452.

ASSIGN COMPONENT 'MATNR' OF STRUCTURE <dyn_table> TO <FS_ANY>.

<FS_ANY> = V_MATNR ....

APPEND <DYN_TABLE>

This will work.

The error is becuase its dynamic and at design time while compiling the code it does not kow the name of the columns in DYN_TABLE.

Hi,

you can do some thing like this.....,

assign r_dyn_table->* to <t_dyn_table>.
create data r_wa_dyn_table like line of <t_dyn_table>.
assign r_wa_dyn_table->* to <wa_dyn_table>.
assign component 'FIELD1' of structure <wa_dyn_table> to <w_field>.
<w_field> = '10'.
assign component 'FIELD2' of structure <wa_dyn_table> to <w_field>.
<w_field> = '10'.
append <wa_dyn_table> to <t_dyn_table>.
assign component 'FIELD1' of structure <wa_dyn_table> to <w_field>.
<w_field> = '10'.
assign component 'FIELD2' of structure <wa_dyn_table> to <w_field>.
<w_field> = '10'.
append <wa_dyn_table> to <t_dyn_table>.

DATA: WA_LINE TYPE REF TO DATA.

create data WA_LINE like line of <dyn_table>.

ASSIGN WA_LINE->* TO <dyn_wa>.

LOOP AT xfc.

ASSIGN COMPONENT xfc-FIELDNAME OF STRUCTURE <dyn_wa> TO <FS_ANY>.

CASE xfc-FIELDNAME.

WHEN 'LIFNR'. <FS_ANY> = '1000010452'

WHEN 'MATNR'. <FS_ANY> = V_MATNR.

............

ENDCASE.

ENDLOOP.

APPEND <dyn_wa> to <dyn_table>.

ENDLOOP.

Hi again,

1. <dyn_table>-lifnr = 1000010452.

It will not work.

2. We have to do it in two steps, for each field assignment.

varname = 'ITAB-LIFNR'.

ASSIGN (VARNAME) TO <fs>.

<FS> = '10000010452'.

varname = 'ITAB-matnr'.

ASSIGN (VARNAME) TO <fs>.

<FS> = v_matnr.

regards,

amit m.

Hi ,

One more obstacle.

How do I read from the dynamic internal table?

If I write as

loop at i_itab.

ASSIGN COMPONENT 'MATNR' OF STRUCTURE <fs_dyn_wa> TO <FS_ANY>.

read table <fs_dyn_table> with key <fs_any> = i_itab-matnr

into <fs_dyn_wa>.

endloop.

It gives error.

pls help with ur ideas.

Thanks,

Hi,

check this....

loop at <t_dyn_table> into <wa_dyn_table>.

assign component 'FIELD2' of structure <wa_dyn_table> to <w_field>.

assign component 'T_CELLCOLORS'
of structure <wa_dyn_table> to <t_cellcolors>.

clear wa_cellcolors.

wa_cellcolors-fname = 'FIELD2'.

if <w_field> = '10'.
wa_cellcolors-color-col = '7'.
else.
wa_cellcolors-color-col = '5'.
endif.

append wa_cellcolors to <t_cellcolors>.

modify <t_dyn_table> from <wa_dyn_table>.

endloop.

Regards

Vijay

Hi,

FIELD-SYMBOLS : <FS_TAB> TYPE ANY.

LOOP AT <DYN_TAB> ASSIGNING <FS_TAB>.

ASSIGN COMPONENT 'LIFNR' OF STRUCTURE <FS_TAB> TO <FS_ANY>.

Now, <fs_any> will have the value of LIFNR field.

You can do the same with READ TABLE as well.

ENDLOOP.

Ravi
