Hello Neelima,
I thought about this too, however I faced some issues,
First, the whole trigger to the process is a service sales order.
Second, we start a sequence of operations that has costs, but we don't know what it will produce till after the process, in other words, there's no BOM here. so how can we make a sales order like this trigger process which we don't have complete data about its quantities.
Thank you
