Selecting a control from different pages using a rule on a Tab page - SAP MDK

[EacostaJh]

Hi Experts,
I have a tab page that has two tabs and each tab points to different pages where each page has its own controls

From the toolBar button I activate a Rule where I want to obtain the elements of each page that has the tab.

This has my rule but it doesn't work for me

You have it just about right but you will want to include #Value in your target path to get the value of the control as opposed to the control reference.  I did a quick test using this rule and it worked as expected.

export default function GetTabFieldValues(context) {
    let ta_sp = context.evaluateTargetPath('#Page:TabA/#Control:FCSimpleProp/#Value');
    let ta_lp = context.evaluateTargetPath('#Page:TabA/#Control:FCListPicker/#SelectedValue');
    let tb_sp = context.evaluateTargetPath('#Page:TabB/#Control:FCSimpleProp/#Value');
    let tb_lp = context.evaluateTargetPath('#Page:TabB/#Control:FCListPicker/#SelectedValue');

    console.log(`Tab A - ${ta_sp} - ${ta_lp}`);
    console.log(`Tab B - ${tb_sp} - ${tb_lp}`);

    return context.getPageProxy().executeAction({
        "Name": '/SCN_00045/Actions/GenericMessageBox.action',
        "Properties": {
            "Message": `Tab A - ${ta_sp} - ${ta_lp}\nTab B - ${tb_sp} - ${tb_lp}`
        }
    });
}
