You'll have a much easier time doing this directly in MySQL.

Something like the following should be essentially all you need.

The data structure here isn't perfect, hence we need some extra code to solve for this. I needed to gather the amount of cars in each location, as well as to allocate the amounts for each invoice, depending on whether or not it was assigned to a location. I broke out the totals for each invoice type so that you can see the components which are being put together, you won't need those in your final result.

So this is just a simple not-exists query:

Find me all the rows where the code and parentcode are the same, but where there does not exist a different parentcode for these rows.

Also note that you cannot have more than 999 invoice codes and still be able to order them, the code and parent code should be integer columns. Otherwise when you want to add INV-1000 it will be considered less than INV-999 because these are strings!

First, in your invoiceSchema, add ref to the customerId field, so it point to CUSTOMERS collection. You can do it like this:

I have explained your previous problem in Question. Since the invoiceInfo is an array and invoiceData also an array inside invoiceInfo, we use map and filter. Then we need to exclude empty array of invoiceData. (This can be done in previous step also like filter-map->filter, but it could be lengthy, thats why I used it in next stage )

Here is the code

The solution is simple. You need to add a schemaVersion property to your root class and annotate it with @XmlAttribute, not with @XmlElement.

What if you move this to the FROM clause? I would phrase this as:

This is happening because in the h4 line that you specified, you are trying to retrieve a DOM node with the id "QuantityBox" + props.identifier.toString(). Your code is unable to retrieve a DOM element with a matching id, causing document.getElementById(qty) to return null. null doesn't have any properties, so document.getElementById(qty).value is throwing an error specifiying that it cant access property value of null. Also, if you want to manipulate DOM elements directly, the React way is to use React Refs. You should be able to achieve your desired result with that.
