WebDynpro: "Make a Table-Row inactive or not selectable" ???

Hi at all,

how can i make a Table-Rowinactiveornot selectable???

I have in my output(Table) many rows, and if one of this ROW-Information have in the Column "BLART" a "DR", than it must be "inactive" or "not selectable"!!! But all other Rows, should be active and selectable!

In ALV-Table (ABAP) i can change the "Fieldcatalog" but how can i realize it in WebDynpro ?

Regards

Ersin
