Fill table control

Hello gurus

I have created a screen with a table control, this table control needs to be filled with the content of an internal table when displaying the screen.

If I fill this internal table in the associated report before

CALL SCREEN 100.

Then it the table control is filled when executing the report.

But if I fill it after

CALL SCREEN 100.

or if I call the screen via the transaction the table control is empty.

I have tried filling the internal table in the module called by the PBO but it does not work either.

Thanks for your help
