Variable Set with Client Script (onLoad)

[EliaquimS]

Good morning! How do I get a value from within the multirow variable and send it to a variable that is not in the multirow?

Do you want to do this after the MRVS is populated, like onLoad of the RITM/Catalog Task, or as each row of the MRVS is populated/edited, or wait until onSubmit of the record to ensure it is accurate with any row edits or deletions?

As each row of the MRVS is populated/edited.

Since you want to do this with each MRVS row addition/edit, you can use an onSubmit Catalog Client Script like this that applies to the MRVS, not the Catalog Item:

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

where 'v_manager' is the name of the Catalog Item variable.  Note that this will replace the value with each row.  If you want to append the value, use something like:

		parent.g_form.setValue('v_manager', parent.g_form.getValue('v_manager') + ' Bob');

For the Service Portal method to work, you also need this onLoad Catalog Client Script that applies to the Catalog Item:

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;
	}
}

Try this 

function onLoad() {
    // Get the multi-row variable (replace 'multirow_variable_name' with the actual name of the multi-row variable)
    var multiRowVariable = g_form.getValue('multirow_variable_name'); 

    // Assuming the multi-row variable is a list or an array, you can access specific values:
    // Example: Retrieve the first row's value in a specific field (e.g., field 'item_name')
    var firstRowItemName = multiRowVariable[0].item_name; // Replace 'item_name' with the actual field name in the multi-row

    // Now, assign this value to another variable that is not in the multi-row (replace 'single_variable_name' with the actual variable name)
    g_form.setValue('single_variable_name', firstRowItemName);
}
