Dear sir, We have issued Tax invoice on 24.04.2018 and also issued debit note referring the said invoice on 27.04.2018. when we are uploading the debit note in GST Portal , it shows the message "original invoice can not be tracked"

There is problem with the portal. If the debit note or credit note is issued in the same month it cannot track the original invoice because you would be uploading the original invoice also in the same month. Due to this, it is advised to issue debit note in subsequent month.
Alternatively change the original tax invoice issued to the recipient if it is supply of service (in case of goods E-way bill issue will be there) instead of issuing debit note subsequently.
Further to the above information i have noticed that there is separate table (9B) in GSTR-3B to add the details of debit note or credit note. Using the said table you can add the details of debit note, credit note issued in the same month of original tax invoice.
