Re: Manufacturing advice needed - materials of measured units being consumed partially

One scenario would be to use 
1 Roll  (=1000m, or 10,000cm) does not mater - it is one roll.

Your 100m final cable would require at least (.1 Roll).  It cannot be made from 2 pieces of 50m (or .05 and .05)
I would reduce the 1000m down to 100 m pieces  (1pc 100m cable), or simply down to any "length" you have as a Piece.
Your BOM requires 1 single piece of 100m or more and cannot be comprised of 2 x 50m piece.

(of course you could splice them, but that is not the conversation)

The main concept is you are not stocking "per meter" but are instead stocking "per piece/roll what have you)

The same process could go towards any finished length and start with any roll size, but the concept is you are still boiling down to a usble piece.  You may have some scrap if you are using odd numbers like 13m for instance.

Likely a more elegant solution but my thought about it just now
Good luck,

thank you for answer. Yes it does make sense. But will it cover scenario where I have let's say 2 rolls with 50m remaining on each and I want to produce 100m final cable? Because in such case a completely new roll should be ordered as I cannot join those 2 50m pieces together... So it comes to a requirement here that you just do not track the total number of meters remaining but you need to track each roll individually. Similar example would be a woodmaker who needs certain sizes of wood for various products (chair, table, ...) and he procures wood in 3m planks. What is your opinion?

Best regards
