I am trying to create a very similar process. I have a custom object Job (master ) and other custom object Steps (child ) . Both of these are children in a master detailed relationship.
In a Job Object there are two record type 1. Lamination and 2 frames. In lamination there are job allocation steps like Plywood cutting, Past, tempering etc. Frame also has same things.
I need a process to create a new Order (job) which will automatically create new multiple steps, not a single step. I want multiple steps like, when I select lamination or frame all relevant job allocation steps to be created. I am trying to use process builders’ which is creating only one step but I want multiple relevant steps for each record type
