Hi @JustinasZ ,
You can append something unique like an invoice number to the email subject when you send it e.g. Test1 - 1234
In the other flow, create the flow with Test1 subject filter. Extract the invoice number using the below expression whilst replacing the static text with the dynamic content for subject
@trim(last(split('Test1 - 1234', '-')))
Use the output in your Excel list rows in table odata filter.
Regardless, you will have issues with extracting the cost centre in the body of the replied email as the original email the user is replying to will muck up the response.
Could you create an Approval step instead?
