Creating relation after uploading data

Dear all,
I have two types of data in my database which should be related. Ordes and Order-Acknowledgements.
By concept I delete the full list of orders on a regular basis and upload the data again from a CSV. After uploading the data I’d like to restore the relation to the Order-Acknowledgement. Both data-types have a field with an ID which can be used to match Order and Acknowledgement.

I would be very thankful for a hint, how to create the relationship of these tow data-types after uploading the orders.

Thank you in advance.
Lucas
