Hi,

1. The simple list display

a. Leading function-module

ii. REUSE_ALV_GRID_DISPLAY (the current version)

These function modules take various internal table, and generate a standard display, on an ALV-standard screen.

b. How to pass on the fields to be printed

This is done by passing an internal table called the field-catalog. It consists typically of the

u2022 internal table-field name,

u2022 the output length,

u2022 the name to be displayed for the column,

u2022 the justification

u2022 formatting, like number of decimals, bold/normal and so on.

REUSE_ALV_GRID_DISPLAY : This is the function module which prints the data.

The important parameters are :

I. Export :

i. I_callback_program : report id

ii. I_callback_pf_status_set : routine where a user can set his own pf status or change the functionality of the existing pf status

iii. I_callback_user_command : routine where the function codes are handled

iv. I_structure name : name of the dictionary table

v. Is_layout : structure to set the layout of the report

vi. It_fieldcat : internal table with the list of all fields and their attributes which are to be printed (this table can be populated automatically by the function module REUSE_ALV_FIELDCATALOG_MERGE

vii. It_events : internal table with a list of all possible events of ALV and their corresponding form names.

II. Tables :

i. t_outtab : internal table with the data to be output

Also, if we are using a data-dictionary structure for the display, we can

avoid creating this internal table by making use of the function

REUSE_ALV_FIELDCATALOG_MERGE.

B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.

The Important Parameters are :

I. Export :

i. I_program_name : report id

ii. I_internal_tabname : the internal output table

iii. I_inclname : include or the report name where all the dynamic forms are handled.

II Changing

ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is

declared in the type pool SLIS.

Hope this helps you

Regards

Shiva
