Here is my below code :
DATA : lv_sum_wrbtr         TYPE dmbtr.
lv_sum_wrbtr = lv_sum_wrbtr + lv_wrbtr.

APPEND VALUE #( vendor = 'TOTAL'
                        txbhw   = lv_sum_txbhw
                        gst     = lv_sum_wrbtr
                  tot_inv_value = lv_sum_tot_inv_value ) TO lt_mail_mails.

CALL FUNCTION 'WWW_ITAB_TO_HTML'
          EXPORTING
            table_header = wa_header
          TABLES
            html         = t_html_x
            fields       = t_fields
            row_header   = t_header
            itable       = lt_mail_mails.

ls_html_x-line 

= '<P>' && 'Please be adviced that, until the issue is resolved, above mentioned GST amount <b>INR. '
        && lv_sum_wrbtr &&' </b> will be temporarily put on hold in your account. We will make the payment as soon as ITC appears in GSTR 2B.' && '<br>'.

Please check format options of string templates.
