Hey Guys,
I am useing WEBI and I am having problem:
I want to sum up the number of responses according to the date the message was sent, and not according to the date the customer replied.
I have two metrics: Move_To_channel_DT (the date the customer was sent the message) and response_date (the date the customer responded).
For example, if customer A was sent a message on 12/12 and the customer replied to it on 15/15, I would like to consider it as a response to 12/12.

This is The final table:

Thanks,
