Hi Technical Consultants,

I am working on SD Module.I have to display ALV grid for Revenue report.Please guide me in using dynamic internal table,as the number of columns for the report is not fixed.Also I need to take the sub total of each row into the last column.

Please help me with issue.

Thanks.

hi Sneha,

try out this simpler dynamic internal tables

REPORT ZSAMPLEPRG.

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.

*In this added the column needed

line = ' CITYFROM CITYTO AIRPTO'.

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.

Try putting break point in the loop u can see it

Reward points if it is useful

Hi Sneha,

First u need to create the fieldcatalog for the structure [ internal table structure]. That is done using the FM 'REUSE_ALV_FIELDCATALOG_MERGE'. After that u need to pass this fieldcatalog to a method 'CREATE_DYNAMIC_TABLE' of class 'CL_ALV_TABLE_CREATE' to create dynamic table.

*********

Data : it_fcat type slis_t_fieldcat_alv,

is_fcat like line of it_fcat,

it_fieldcat type lvc_t_fcat,

is_fieldcat like line of it_fieldcat.

Data :new_table type ref to data.

field-symbols : <l_table> type standard table.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_structure_name = l_segname " [<b>Structure Name</b>]

CHANGING

ct_fieldcat = it_fcat[].

loop at it_fcat into is_fcat.

Move-corresponding is_fcat to is_fieldcat.

is_fieldcat-fieldname = is_fcat-fieldname.

is_fieldcat-ref_field = is_fcat-ref_field.

is_fieldcat-ref_table = is_fcat-ref_table.

append is_fieldcat to it_fieldcat.

endloop.

****Create new table

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = it_fieldcat

IMPORTING

ep_table = new_table.

if sy-subrc eq 0.

assign new_table->* to <l_table>.

endif.

Thanks to all Techincal consultants.The steps were really helpful & I implemented the same in my program.
