Nancy sent me this problem:
 
We just had a problem with a WO that was closed yesterday.  All the  
costs went to WIP Variance instead of to the part.
 
The costs of the material issued was correct.  If I took the total parts
issued divide by the # parts issued to finished prod, the amount was
exactly what went into WIP variance.  The part # is a finished part.  
Prior WO's were correct.
 
Can you please ask how this could happen?  We need to know what  
drives this kind of issue.  
 
Anybody have any ideas?

Cathy,
 
Nancy says " Issued at actual costs.".  Is that what you are asking?

No I meant at what cost was the finished part # finished at in WO-I Enter Finished PRoduction.   I have seen all the costs for a finished good part# go to WIP variance when either
    1) The part was not actually finished in WO-I before it was closed or  
    2) The work order was finished at $0 actual cost because the actual cost was not updated in the finish production process and was not correct.
 
Hope this helps..
