To populate value from LookUpSelect Box variable from MRVS to single line text variable outside MRVS

[Amrutha K V]

Hi Team,

I have a LookUp Select Box variable named 'Plant' in PackSize MultiRow Variable set(MRVS). 
Have a Single Line Text variable named 'PlantOutside' in Outside MRVS. 
When user select a value for Plant from PackSize MultiRow Variable set, i want to autopopulate that value in my Single Line Text variable which is present outside MRVS.
I have tried the below OnChange Catalog Client script in PackSize MRVS level when the Plant variable changes,but i cannot able to set the value in single line text variable. Please help me 

Onchange of Plant inside MRVS:

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || !newValue)

        return;

    // newValue = AU01 - Australia Direct

    alert('Selected Plant:1 ' + newValue); -- > working 

    try {

        var parentForm = g_service_catalog.parent;

        if (parentForm) {

            alert('Selected Plant:2 ' + newValue); -->working

            //var plant = g_form.setValue('plantoutside', newValue);

            //var plant = parentForm.g_service_catalog.setValue('plantoutside', newValue);

            var plant = parentForm.setValue('plantoutside', newValue);

            alert('Selected Plant:3 ' + plant); -- > not working 

        }

    } catch (e) {

        console.log(e);

    }

}

Please help me to populate value in PlantOutside variable from Plant variable . 

Thank you

g_service_catalog does not (yet?) work to set values, you can only getValue.  You can use a script like this:

if (this) { //Service Portal method
	this.cat_g_form.setValue('v_manager', newValue);
} else { //native UI method
	parent.g_form.setValue('v_manager', newValue);
}

If you are using Service Portal / ESS, this script is also needed onLoad of the Catalog Item, not the MRVS:

function onLoad() {
	if (this) {//we only need to do this for Service Portal
		//We need to make the g_form object for the parent item available from the MRVS window
		this.cat_g_form = g_form;
	}
}

Hi @Amrutha K V,

Since your requirement is to populate a variable outside the MRVS whenever the Plant value changes inside the MRVS, you can achieve this directly from the MRVS onChange Client Script without using an additional trigger variable.

Create an onChange Catalog Client Script on the Plant variable inside the MRVS:

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || !newValue)
        return;

    try {

        parent.g_form.setValue(
            'plant_outside',
            newValue
        );

    } catch (e) {
        console.log(e);
    }
}

We have tried the above script and its not working as expected

You could use an onChange script from the catalog item itself and parse the value from the mrvs. Something like this could work:

var mrvsVal = JSON.parse(g_form.getValue('plant mrvs'));
var updatedValue;
for (var i = 0; i < mrvsVal.length; i++) {
    if (mrvsVal[i].<list collector field name>) {
		updatedValue = mrvsVal[i].<list collector field name>;
    }
}
g_form.setValue('<PlantOutside variable>', updatedValue);
