for example:

one order (1000 products to be produced)
there are multiple production sub-orders below, the quantity cannot be determined! ..
(for example, you applied for a sub-order [production of 100products], 6.1 applied for a sub-order [production of 500products], 6.2 applied for a sub-order [production of 400products])

put the process of producing sub-order into the sub-process of activiti. The problem is that you don"t know the number of instances of the sub-process when you create the sub-process, so how to solve it? Please give me a direction to think.

am I not writing clearly? Is there anyone.
