When the material has been issued to the wrong work order the process is to enter a negative issue in WO-G which is to take the parts and the cost back out of the work order.  Sometimes the system issues the part at 0  dollar cost. This creates a series of problems starting with to much material cost and when you reissue the positive to put it back to where it was before the fix it might issue at the correct cost and then there are to many pieces and to much cost times two.  What are the options for fixing this and how do we keep it from happening again.

This is one of my favorite topics on which I have written epics-- latest in Manufacturing :

Thanks, Kevin, for your response.  
 I did some further testing in a dummy company yesterday and had a problem with the backout method again.  I had forgotten what it does when it goes wrong;  what happened was that the backout showed up in the work order and job costs files, ie there were no transactions for the part numbers, and in the GL there were both issue and backout transactions, but the inventory file has only the issue and not the backout, so our inventory is off.  There is not an easy way to fix it, except I guess in maintain database delete the inv transaction that issued.  NOt something I like to do.    
It was obvious during that backout that something was wrong.  This was a backout of items backflushed in a sequence.  There were 5 items.  Three backed out just fine, but the 4th and 5th  stayed on the screen flickering for some time before clearing.  
 
Right now we are using negative issue since at least we can see the transactions everywhere.  The only issue is the correct avg cost as you said, and sometimes the WO-A issues screen is incorrect.  That's better than inventory being wrong with no easy way to fix it.
