Former Member — Wed, 19 Dec 2007 14:36:34 GMT

Hi All,

Could any body please explain me in detail the use of all ALV function modules and parameters required for those FM's.

If possible send me some example program consists of all FM's.

Thanks in advance,

Rakesh.

Hi,

pls find the below list of ALV function modules.

ACC_REUSE_ALV_LIST_DISPLAY

REUSE_ALV_GRID_DISPLAY_LVC

REUSE_ALV_GRID_LAYOUT_INFO_GET

REUSE_ALV_GRID_LAYOUT_INFO_SET

SLVC_SERVICES_2

REUSE_DOUBLE_ALV

basically you can display report the reports in 5 ways using ALV's

1) List display

2) Grid display

3) Blocked ALV

4) Hirerarchy display

5) Tree ALV-----this we can achieve by using OOPs.

the below are the major ALV fm we use

REUSE_ALV_LIST_DISPLAY

EUSE_ALV_GRID_DISPLAY

REUSE_ALV_BLOCK_LIST_DISPLAY

REUSE_ALV_HIERSEQ_LIST_DISPLAY

do one thing go to SE37 type any of this FM name and press CTRLSHIFTF3, whcih will give you the list of programs which are using this FM, take a look into that programs, in this way you can easily get the examples of all the function modules.

Reward if useful.

Regards,

Sreeram.

Dear Rakesh,

Function modules used in ABAP List Viewer are listed as below:

1. REUSE_ALV_VARIANT_DEFAULT_GET

2. REUSE_ALV_VARIANT_F4

3. REUSE_ALV_VARIANT_EXISTENCE

4. REUSE_ALV_EVENTS_GET

5. REUSE_ALV_COMMENTARY_WRITE

6. REUSE_ALV_FIELDCATALOG_MERGE

7. REUSE_ALV_LIST_DISPLAY

8. REUSE_ALV_GRID_DISPLAY

9. REUSE_ALV_POPUP_TO_SELECT

The commonly used Function Modules and their explanations are:

A. REUSE_ALV_LIST_DISPLAY: This is the function module which prints the data.

B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV.

C . REUSE_ALV_EVENTS_GET: Returns table of possible events for a a list type

D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.

E. REUSE_ALV_GRID_DISPLAY: A new function in 4.6 version, to display the results in grid rather than as a list.

For a program you can refer to the link given below.

[ALV Grid Programming|http://www.abap4.it/download/ALV.pdf]

Please reward points if found helpful.

You would wnat to use: REUSE_ALV_GRID_DISPLAY

You dont' have to populate everything. Just the following is fine. But you do need to setup field catelog, events, sort catelog if you use it. itab_rpt is where you pass in your table for display. The field name will have to match the field name you set in the field catelog
