Replace SKU in the invoice with a custom attribute

[nicogranzow]

Hello,

I'm trying to replace the SKU in the invoice with a custom atribute I've created.

I've changed the header in vendor/magento/module-sales/Model/Order/Pdf/Invoice.php which worked out fine.

But when I change the getSKU in vendor/magento/module-sales/Model/Order/Pdf/Items/Invoice/DefaultInvoice.php with the new attribute to getLPS, the new attribute does not appear in the invoice, the place is blanc. Is there some other place where I have to change it?

thanks
