Working with Multiple dynamic internal tables

Working with Multiple dynamic internal tables

ByBhumika Mahawar, YASH Technologies

The main objective of this article is not to show how to display two ALVs on a single page rather it mainly focuses on the use of dynamic tables in ALV. My requirement was to create two dynamic table and display data into them. The first dynamic table was created in the same way as already known using the method create_dynamic_table but the problem was the second dynamic table creation.

To do this, you dont need to use the same method again rather the RTTC concept helps us in the same. The below code illustrates the same and displays the data in an ALV as shown in the diagram below.

REPORT ztest.

**** Data declarations

DATA:

dtab TYPE REF TO data,

newstr2 TYPE REF TO cl_abap_typedescr,

tab_type1 TYPE REF TO cl_abap_tabledescr,

lref_ditab TYPE REF TO data,

lref_new_line TYPE REF TO data.

**** Field-Symbols declarations

FIELD-SYMBOLS:

TYPE ANY TABLE,

TYPE ANY TABLE,

TYPE ANY.

**** Field Catalog declarations

DATA:

ls_fcat TYPE lvc_s_fcat,

lt_fcat TYPE lvc_t_fcat.

**** Data declarations for ALV Display *

**** Object variable for ALV grid

DATA:

obj_my_alv_grid TYPE REF TO cl_gui_alv_grid.

**** Object variable for ALV Container

DATA:

obj_r_container TYPE REF TO cl_gui_custom_container.
