GSTR 3B - ECB Interest Invoice/Reimbursement Invoices

Dear Friends,

Usually we are receiving ECB loan interest from our Parent Co, Japan in USD. But, we are accruing the interest in our books on monthly basis. There is no GST for this Invoice. We need to show this transactions in our GSTR 3B or not required?... as well some times we are receiving travel reimbursement invoices from our Parent Co, Japan. This transactions would be shown in GSTR 3B or not?
