What i am trying to acheive is.
I have 3 functions A, B, C ,D and 8 line items. What i want 4 items should go through b,C,D where as other through A,B,C,D .. And secondly function B,C,D for first 4 line item should not wait for other set of 4 line item.
Hope its clear.
Do you need something like this?
If that's what you need, you need to split the items between different instances of function B, C, D; most likely through granularity.
