Error in Dynamic table creation

Former Member — Fri, 18 May 2007 12:42:02 GMT

Hello Friends ,

I am using 4.6c version, while creating the dynamic internal table its giving the problem mentioned below.

my main internal table is having 5 fields depends upon the paramers (column positions in the main internal table)on the slection screen i have to keep the corresponding columns data of main table in to the dynamic internal table:

if parmeters 3 and 5 have given means i should keep 3rd and 5th field form the main internal table to dynamic internal table .

my main table is ITAB_MAIN which is having 5 fields

I declared the as follows.

DATA : ITAB_SUB TYPE REF TO DATA,

NEW_LINE TYPE REF TO DATA,

IT_FIELDCATALOG TYPE LVC_T_FCAT,

WA_FIELDCATALOG TYPE LVC_S_FCAT.

FIELD-SYMBOLS :<IT_FINAL> TYPE STANDARD TABLE,

<WA_FINAL> TYPE ANY,

<W_FIELD> TYPE ANY .

I created the field catalog according to the parmeters given on the selection screen

i.e IT_FIELDCATALOG

CLEAR IT_FIELDCATALOG.

WA_FIELDCATALOG-ROW_POS = 1.

WA_FIELDCATALOG-COL_POS = 1.

WA_FIELDCATALOG-FIELDNAME = P_FIRST.

WA_FIELDCATALOG-TABNAME = 'ITAB_MAIN'.

WA_FIELDCATALOG-INTLEN = 10.

WA_FIELDCATALOG-OUTPUTLEN = 10.

APPEND WA_FIELDCATALOG TO IT_FIELDCATALOG.

WA_FIELDCATALOG-ROW_POS = 1.

WA_FIELDCATALOG-COL_POS = 2.

WA_FIELDCATALOG-FIELDNAME = P_SECOND.

WA_FIELDCATALOG-TABNAME = 'ITAB_MAIN'.

WA_FIELDCATALOG-INTLEN = 10.

WA_FIELDCATALOG-OUTPUTLEN = 10.

APPEND WA_FIELDCATALOG TO IT_FIELDCATALOG.

*--Create the table dynamically

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE

EXPORTING

I_STYLE_TABLE =

IT_FIELDCATALOG = IT_FIELDCATALOG

IMPORTING

EP_TABLE = ITAB_SUB

E_STYLE_FNAME =

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 ITAB_SUB->* TO <IT_FINAL>.

CREATE DATA NEW_LINE LIKE LINE OF <IT_FINAL>.

ASSIGN NEW_LINE->* TO <WA_FINAL>.

i am inserting the entries to final internal table as follows

LOOP AT ITAB_MAIN.

MOVE-CORRESPONDING ITAB_MAIN TO <WA_FINAL>.

APPEND <WA_FINAL> TO <IT_FINAL>.

ENDLOOP.

But here MOVE-CORRESPONDING is not working and its giving error as follows

<WA_FINAL> is not a structure or internal table with header line.

In 4.7c its working fine but in 4.6c its not working and i am getting the above mentioned error .

So could you please give me possible solution .

Thanks in advance,

Arvind.

Hi,

DATA WA_FIELDCATALOG TYPE LVC_S_FCAT.

DATA IT_FIELDCATALOG TYPE LVC_T_FCAT.

DATA:DYN_ITAB TYPE REF TO DATA,

WA TYPE REF TO DATA.

FIELD-SYMBOLS: <DISP_TABLE> TYPE TABLE,

<WA> TYPE ANY.

WA_FIELDCATALOG-COL_POS = 1.

WA_FIELDCATALOG-FIELDNAME = 'P_FIRST'.

APPEND WA_FIELDCATALOG TO IT_FIELDCATALOG.

WA_FIELDCATALOG-COL_POS = 2.

WA_FIELDCATALOG-FIELDNAME = 'P_SECOND'.

APPEND WA_FIELDCATALOG TO IT_FIELDCATALOG.

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE EXPORTING

IT_FIELDCATALOG = IT_FIELDCATALOG[]

IMPORTING

EP_TABLE = DYN_ITAB.

ASSIGN DYN_ITAB->* TO <DISP_TABLE>.

CREATE DATA WA LIKE LINE OF <DISP_TABLE>.

ASSIGN WA->* TO <WA>.

try with this

LOOP AT ITAB_MAIN.
ITAB_MAIN-field1 = <WA_FINAL>-field1.
ITAB_MAIN-field2 = <WA_FINAL>-field2.
ITAB_MAIN-field3 = <WA_FINAL>-field3.

APPEND <WA_FINAL> TO <IT_FINAL>.

ENDLOOP.

Hi,

Try this coding.

if u know the no. of fields in itab_main (say n).

LOOP AT ITAB_MAIN.

*for this u can maintain another loop.

ASSIGN COMPONENT 1 OF STRUCTURE <WA_FINAL> TO <l_field>.

ASSIGN COMPONENT 2 OF STRUCTURE <WA_FINAL> TO <l_field>..

append <wa_final> to <it_final>.

ENDLOOP

with regards,

Hello,

Here if i am doing like this

<WA_FINAL>-field1 = ITAB_MAIN-field1 .

<WA_FINAL>-field2 = ITAB_MAIN-field2 .

<WA_FINAL>-field3 = ITAB_MAIN-field3 .

its not working its giving an error message like as follows.

<WA_FINAL> has no structure and therfore no component called field1.

That too i would like to have in my final internal table IT_FINAL only the fileds that have given in the selection screen dynamically.

Could you please give me possible solution.

Thanks,

Arvind.

Hello Arvind

Based on the way you build the fieldcatalog I assume that your "dynamic" has the same structure as your ITAB_MAIN but only certain columns should be displayed depending on the selection criteria.

If this is correct then you do not need a dynamic itab at all but you can use ITAB_MAIN directly as output for your ALV list. In order to hide certain columns simply adjust the <b>fieldcatalog</b>, e.g.:

" (1) Build fieldcatalog for all 5 fields

" Depending on the selection criteria columns 3 & 5 should be hidden
  LOOP AT gt_fcat INTO ls_fcat
                            WHERE ( fieldname = 'P_THIRD'    OR
                                           fieldname = 'P_FIFTH' ).
    ls_fcat-tech = 'X'.  " hidden on ALV list and layout
"    ls_fcat-no_out = 'X'  " only hidden on list, but can be choosen from layout

    MODIFY gt_fcat FROM ls_fcat.
  ENDLOOP.

Regards

Uwe
