Need invoice numbers for material masters.

Dear experts,

I have a list of approx. 200 PO numbers (not SO numbers) and material masters. I need to find invoice# for each PO#. Could you please help me what is the fastest way to find the invoice# using the data mentioned above? I do not want to enter each order separately and check document flow in order to find invoice, would like to find some faster way to do this 😊

Hope you can help me!

Thank you in advance!!
