im not able to enter 2 product and serial no in the data field. One one is getting entered.

Firstly make your request JSON in the proper format if you want to insert two products which you are getting from request data.
For example, your request JSON should be in the flowing format:
{"refno1":"x", "refno2": "y", "prodregdate": "2019-04-19T18:30:00.000Z","data": [{"product": "product_1_object_id","oemwarrantyfrom":"2019-04-19T18:30:00.000Z", "oemwarrantyto": "2019-04-19T18:30:00.000Z","warrantyfrom":"2019-04-19T18:30:00.000Z", "warrantyto":"2019-04-19T18:30:00.000Z","serialno":"123" },{"product": "product_2_object_id","oemwarrantyfrom":"", "oemwarrantyto": "2019-04-19T18:30:00.000Z","warrantyfrom":"2019-04-19T18:30:00.000Z", "warrantyto":"2019-04-19T18:30:00.000Z","serialno":"456" }],"customersubdepartmentid":"departement_object_id","customerid":"customer_object_id","customertypeid":"customer_type_object_id","remarks":"anything"}
If you are using POSTMAN then you can try this JSON in the "raw" option.
Then in your code, it should be like below:
router.post('/add', (req, res)=>{
const newProdReg = new ProdReg({
_id: new mongoose.Types.ObjectId(),
refno1: req.body.refno1,
refno2: req.body.refno2,
prodregdate: req.body.prodregdate,
data: req.body.data, // This will be type array with two products details
customer: req.body.customerid,
customertype: req.body.customertypeid,
department: req.body.customersubdepartmentid,
remarks: req.body.remarks
});
newProdReg.save().then(prodreg => res.json(prodreg));
});
Please match your request param with JSON I took it from your schema.
