Any question answered...

I think this is what you're trying to do

app.preferences.rulerUnits = Units.PIXELS;
var doc = activeDocument;
var Orientation = parseFloat(doc.height / doc.width);

if (Orientation >= 1) {
    var wFactorP = parseFloat(7016 / doc.width);
    var hFactorP = parseFloat(9933 / doc.height);

    if (wFactorP > hFactorP) {
        doc.resizeImage(70­16, undefined, undefined, ResampleMethod.BI­CUBIC);
    }
    else {
        doc.resizeImage(undefined, 9933, unde­fined, ResampleMethod.BICUBIC)
    }
}

else if (Orientation < 1) {
    var wFactorL = parseFloat(9933 / doc.width)
    var hFactorL = parseFloat(7016 / doc.height);

    if (wFactorL > hFactorL) {
        doc.resizeImage(99­33, undefined, undefined, ResampleMethod.BI­CUBIC)
    }
    else {
        doc.resizeImage(undefined, 7016, unde­fined, ResampleMethod.BICUBIC)
    }
}
