Setup Service Call module for serialized and non-serialized products in SAP Business One

We require to setup the Service Call module on SAP BO 9.3 Hana to process both, SERIALIZED AND NON-SERIALIZED PRODUTCS (native solution only processes serialized and we have many non-serialized ones that would like to keep this way for ease of use), and set configurations to start using it for product’s RMA and returns tasks allowing to assign a technician to each case and sending an automatic email to customers when RMA is received and second one after it’s solved showing solution: product repair, replacement for new one or returned the same when found product to be working properly.
