hi,

chk whether ur internal table is with header line.

if it is with header line the use refresh instead of clear e.g. refresh itab.

Hello,

Move your select statement to PBO and

use a "loop with control" statement instead of REFRESH CONTROL statement,

and set TBC_QT-LINES = row count of your internal table.

LOOP WITH CONTROL TBC_QT.

MODULE TRANSP_ITAB.

ENDLOOP.

in the module TRANSP_ITAB :

READ TABLE itab INDEX table-current_line.

By this way you are moving the content of internal table to screen

on every time PBO - PAI

Demo program DEMO_DYNPRO_TABLE_CONTROL_1 is a good example for that.

I hope it helps you.
