dynamic tables

[former_member188594]

Hi all,

what is a dynamic table ? How do i go about creating one. Actually, my requirement is to display a set of fields based on selection screen with 3 input fields. Any help/suggestion is appreciated. Thank you.

Hi

Use this method

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = it_fldcat

IMPORTING

ep_table = new_table.

ASSIGN new_table->* TO <dyn_table>.

• Create dynamic work area and assign to FS

CREATE DATA new_line LIKE LINE OF <dyn_table>.

ASSIGN new_line->* TO <dyn_wa>.

Hi,

Can u b more clear in ur requirement?

As to wat i hav understood, its actually simple to specify the fileds in ur selection screen thro parameters or select options.

Then fetch the required fields based on ur selection screen values, jus by writing a select query with a "where condition".

Then display the content in ur it_tab using ALV or write statements.
