How to report on primary key in one file and not the other when doing a field comparison

[pderwa12]

I have a simple workflow where I am comparing one file to another file in order to see the changes that were made between the two files.  Alteryx is only picking up the records where there is a match on the primary key. I want the output to show me all the changes, even if there is no match on the primary key.  What do I need to do to fix this.  Here is a snapshot of my workflow.  Is there a formula I can add that will show all primary key fields even if they do not all exist in the new file or vice versa?

Actually, the only records I am interested in seeing are those records where there is not a match between the amounts associated with the PO; including when a PO number/value exist in one file and not the other.  My current workflow shows all the records where there a match between the PO numbers and then calculates the difference between the values of each PO.  I don't need to see the POs where these is a match between the PO amount in one file and the PO amount in the other file.  I only want to see the PO number and its values when a match does not exist in the two comparison files.  That could be if there is a match between the PO numbers but the values are different or a PO exists in one file and has a value and the PO does not exist at all in the other file.  I want to see all of those.

@binuacs I was able to get it to work using this latest diagram.  Thank you very much.  This is what my workflow looks like now:
