Guidance regarding the flow to reach goods shipment

[aishwarya]

Hello, I am working on a project for which i need to develop an ERP. Since I am new to OfBiz and ERP Systems, I am finding it difficult to understand the flow to create and reach till invoice generation and goods shipment. It would be helpful if you could tell me the flow from product creations, their business partners, customers, inventory,and all other related steps.

Thank you :)
