Using a Table control with an internal table

Updated May 18, 2018

Table control : TC1
Internal table : it_zsd00003

In the attributes of the table control, select w/SelColumn to get a selection
column on the table control, and give a name (In this example IT_ZSD00003-LINESEL).
Remember to include the field IT_ZSD00003-LINESEL in the
internal table ( linesel(1) type c, ).

When used with an internal table, remember to program
the update functionality of the database tables. Update and
validation can be done when leaving the screen or in PAI using controlname-
current_line (E.g. TC1-current_line ) to indentify the entry in the internal table.

Deleting a single line selected with the selection column:

form delete_record.

loop at it_zsd00003.
if it_zsd00003-linesel = 'X'.

delete from zsd00003
