something very verbose for something very simple. What is being duplicated though? Is it the "assortiment"? As Tom says and resays, you really need to supply more info for a reliable answer. But I'm prepared to hazard a guess:

I assume that "assortiment" is the "job lot" of goods assigned to a store in a chain or franchise system. It riles me, for instance, that the local shoe shops get supplies of shoes with a certain number of each size. Each supply lot contains ONE pair of size 45 men's shoes, which means that if some other big-footed oaf gets there before me, I miss out (and will they order a size 45 for me, from a shop in an area where everyone is small, maybe, if not from head office? Oooooh noooh!). And no-one finds it strange that they are consistently left with dozens of size 43 downwards and nothing above ...

So: Job lots for each store can be duplicated (for a supply twice as big), based on the job lot for each store (I suppose bigger stores get bigger lots, which in turn could be doubled). If there is one or more new outlets, they are each (in turn) automatically proposed for supply (with one or more/the appropriate job lot(s) ).

Or ... the supply/batch/job lot for each (of the new stores) is automatically proposed.

In other words, for getting supplies
