I am using ZOHO CRM API for creating and updating records. Now, I have created a sale order record with one product on product details section.

Now, I needs to update the sales order record by deleting the existing product from product details section and add a new product on this record.

Is this possible?

If I try to update the sales order record with new product details by using <product no="1"> tag , it will add the new product as second product rather than overriding the first product. I wants to override the first product with new product. 

Anyone can help me with this, please?

Thanks in advance.
