    Hello,

    It may be your code is trying to get lookup value without checking if it is available or not.

    so make sure your in your code you have validation like below

    if(Xrm.Page.getAttribute('Lookupfieldname')!=null && Xrm.Page.getAttribute('Lookupfieldname').getValue()!=null)

    {

    //only then get value

    }

    If this don't solve your issue, share your code here so that someone can help you.

    function engagementOnLoad()

    {

    var customerValue = Xrm.Page.getAttribute("pcc_engagement").getValue();

    if(customerValue !=null)

    {

    var name=customerValue[0].name;

    alert(name);

    }

    else

    {

    Xrm.Page.getAttribute("pcc_name").setValue(name);

    }

    }

    function solutionOnLoad()

    {

    var sol = Xrm.Page.getAttribute("pcc_solution").getValue();

    Why are you assigning value on the else part (where name will be null?), it should be like below:

    function engagementOnLoad()

    {

    var customerValue = Xrm.Page.getAttribute("pcc_engagement").getValue();

    if(customerValue !=null)

    {

    var name=customerValue[0].name;

    Xrm.Page.getAttribute("pcc_name").setValue(name);

    }

    }

    function solutionOnLoad()

    {

    var sol = Xrm.Page.getAttribute("pcc_solution").getValue();

    if(sol!=null)

    {

    var sname=sol[0].name;

    Xrm.Page.getAttribute("pcc_name").setValue(sname);

    }

    }

    Hi Bharath,

    In which form you are getting error , is it Update form or Create Form?

    If  the form type is "create" until and unless you set any value in the lookup field you wont get any name from the lookup , so make sure you first set the lookup value  before get the name in the Create Form.

    As  Mahendar already pointed that in the else part in your code it will enter only when you will get lookup is null and thats why you are getting always null.

    function engagementOnLoad() {
    if (Xrm.Page.ui.getFormType() == 2) { // Update Form
        var customerValue = Xrm.Page.getAttribute("pcc_engagement").getValue();

        if (customerValue != null && customerValue != undefined) {
            var name = customerValue[0].name;
            Xrm.Page.getAttribute("pcc_name").setValue(name);
        }
    }
    else
    {
         
        // Set lookup value first 

        // Get lookup name 

        // Set the lookup name value to text
    }

}

function solutionOnLoad() {
    if (Xrm.Page.ui.getFormType() == 2) { //Update form
        var sol = Xrm.Page.getAttribute("pcc_solution").getValue();
        if (sol != null && sol != undefined) {
            var sname = sol[0].name;
            Xrm.Page.getAttribute("pcc_name").setValue(sname);
        }
    }
    else
    {
        // Set lookup value first 

        // Get lookup name 

        // Set the lookup name to the text

    }
}


    Hope this helps
