Ive already tryed using check box with anchor base and the find element activity,
right now im using anchor base with find elemnt and click on the checkbox
I would definitely not use any Anchors or any Find Elements - this is not needed, as you are using SAP Scripting interface and UiPath can automate all with stable and reliable selectors.
use simple Click Activity and we will click the right checkbox.
If you have to select more elements, then use CTRL+CLICK, the same as Human-being would do it.
