Hi,
What are the events in alvs and which events not used in alvs?
Events in alv and their FM The main events in alv and their FM and why we use these:
1. SLIS_PRINT_ALV.
2. SLIS_T_LISTHEADER.
3. SLIS_T_EVENT.
4. SLIS_T_SORTINFO_ALV.
5. SLIS_T_LAYOUT_ALV.
6. SLIS_T_FIELDCAT_ALV.
and in classic reports what is the sequence of events: === Events are
At selection-screen output.
Initialization.
At selection-screen on field
At selection-screen on end of field
At selection-screen on Radiobutton Group R1. (If you have any radio buttons)
At selection-screen on block b1. (If you have any blocks)
Start-of-selection.
Get node. (if the data is retreived from a logical database)
Get node late. (if the data is retreived from a logical database)
Top-of-page. (if the write statement is in the end-of-selection event or we can say that before the first write statement)
end-of-selection.
and fuction modules are
LISTHEADER - Is used to print the header information in the ALV List. Name, Date, Time, ALV Name and other details are called as Header information. EVENT - Basically this is the FM to handle Event's. When the user needs to do some event operation like when double clicking the a particular field we need to perform some operation. These events are captured by this FM. LAYOUT - This FM is used to define the layout of the List. There are many options available in this FM to define the Layout style. FIELDCAT - These are used to populate the List header. We can change them according to our req.

Hi,
We have 3 types in ALV
1) simple report
2) Block report
3) hirarchical report.
in <b>simple report</b> we have following function modules..
REUSE_ALV_LIST_DISPLAY
REUSE_ALV_GRID_DISPLAY
Reuse_alv_fieldcatalog_merge
Reuse_alv_events_get
Reuse_alv_commentary_write
In <b>block report</b>
A. REUSE_ALV_BLOCK_LIST_INIT
B. REUSE_ALV_BLOCK_LIST_APPEND
D. REUSE_ALV_BLOCK_HS_LIST_APPEND
C. REUSE_ALV_BLOCK_LIST_DISPLAY
in <b>Hirarchical report</b>
REUSE_ALV_HIERSEQ_LIST_DISPLAY
for getting check boxes
in simple field catalog check box option is there just u have pass 'X'
then u will check box.
<b>reward me a points if it is use full answer..</b>
