We created a series of part numbers by copying a series of existing part numbers using IN-L-N.  Then we edited the descriptions in IN-B for all the new part numbers. Now we are rolling up the BOMs and the rountings.  The BOMs roll up properly.  However when we go to roll up the routings in RO-B, the old description shows up on the report.  If we go into RO-A and save each sequence in the routing, the description changes to the new description in the roll-up.  If we don't "touch" each sequence, then the 2nd page of the roll-up has the wrong description.
 
It's a small bug.  It's an annoyance though because we are doing more jobs using the plan where we copy a list of item numbers.
 

We have a similar problem.  We have a part number that displays the wrong description when viewed in WOs.  
The description is always correct in ITEMS module  but not in the MFG module.
So we see the correct item description in IN-B and BM-B but not in Work Orders.  ?  
 
After reading this old thread I wonder if it is because maybe we copied a part number
 
 
This causes our travelers to have an incorrect description.  
Thanks
