Yes, we can generate both classical and Interactive reportS
in ALV..
For classical report in ALV..
Type-pools : slis.
DATA : it_Fcat type slis_T_fieldcat_Alv
wa_fcat type slis_fieldcat_Alv.
Data : itab type standard table of (SOme Structure)
wa like line ot itab.
Start-of-selection.
Select.....
after readig data from database....
we use FM REUSE_ALV_FIELDCATALOG_MERGE
After that We display the Output
We use FM : REUSE_ALV_GRID_DISPLAY ( for Grid Format)
OR
REUSE_ALV_LIST_DISPLAY(for list format)
*****
*&----INTERACITVE ALV*******
We take two Internal tables ...
Data : itab type standard table of ty_marc (Type structure)
itab1 type standard table of ty_mara(TYPE structure)
data : it_fcat type slis_t_fieldcat_alv,
t_Event type slis_t_event,
t_listheader type slis_t_listheader.
we use FM : REUSE_ALV_GET_EVENT
This is function Module is used to catch the EVENTs like
TOP-OF-PAGE and END-OF-PAGE, USER_COMMAND....etc
For interactive Report:
we will give form like
Form User_Command Using ucomm like Sy-ucomm
selfld type SLIS_SELFIELD,
*& we'll call this Subroutine in the FM GRID DISPLAY..
case ucomm.
when '&IC1'. " this is FunctionCode which catchs when
user do some actions.
READ TABLE Itab INTO WA_tab INDEX RS_SELFIELD-TABINDEX.
perform buildcatlog.
perform DataRetrieval.l
Perform Listdisplay.
Perfrom Dispaly.
endcase.
THIS IS HOW WE DO INTERACTIVE ALV...
I THINK THIS WIIL U IN DOING CLASSICAL AND INTERACTIVE
ALV..
