PO, WO audit trail

I would like to know if there a way on the PO “print po copy” option Receipt to see a trail of if parts were billed to wo to the the wo transaction and if it a stock to see the stock level transaction. I am asking this as we are getting parts not being billed to wo correctly when parts are assign to a work order. Also we have some non-file parts being received without a work order. This are rare occasion but causing some errors when doing our year end audit. I am trying to see how we can watch for this error.
