2 Products Line items in one e-invoice

Hi Friends,
Hi how do we create 2 sale line items in one einvoice in the GST e-invoice Excel tool?

We put Doc Number, Date and Type in two line items. But, it is showing error as per screen shot. I spoke to GST seva, they told me put Doc Date, Type and number in 1st row only and put two products like items in two rows.
But 2nd line item is cleared automatically while validating the file.
