Production schedule question.  I have a production schedule part that can run on 3 different lines. On the three production lines upon which I can run the part, I use a percentage of .33.33 and .34.  

If the total amount of the part to be produced obtained from the part's master schedule is not easily divisible by 3 and I run MS Calc, I am getting a mystery 1 unit production schedule.  

Can anyone explain this?  I think it is due to the fact that the total doesn't yield a whole number when multiplied by the percentage and yields a 1 piece production schedule to ensure that the system is planning for ALL of the requirement.  For example, MS says we need 903,168 pounds.  That means production line A (33% and Line B (33%) get 298,045 each (remainder of .44 ponds each) and line C gets a production schedule of 307,077 pounds (remainder of .12 pounds.  The remainders of all 3 lines add up to 1 pound.  Both the production schedule item and the component item have quantity calc rounding set to zero.

SO I have 2 questions:

1.  DO you consider this to be a bug?
2. What do you do with the 1 pound production schedule?  I would think just delete it because you'll never run that small of an amount.

Any help or advice would be appreciated!!
