I am bit new to SAP Demand Planning. I have heard about process chains and started googling it , but i couldnt understand much. As far as my understanding, Background jobs are very much crucial in APO DP and SNP and these can be scheduled through SM36. However , SAP 4.0 has come up with a new functionality to schedule the background jobs , which is a Process Chain. Process Chains are far better than SM36 as we can create the dependencies here. This is how much i understood. Can any1 explain Process chain in more deep and how to create them in system with an example.
