Difference between events 'CREATE' , 'INSERT' custom handlers CAP Node.js

[Ramjee_korada]

Hello Experts,
Can you please help me with the difference between the events CREATE and INSERT? When should I use each one, and what is the best practice? Also, what is the standard sequence of invocation? Based on my debugging, it appears that whichever event handler is implemented first is the one invoked first.

this.before('CREATE', Properties, async (req) => {
}

this.before('INSERT', Properties, async (req) => {
}

Best regards,

Hi Ramjee,

You can check the official CAP documentation here:
👉 https://cap.cloud.sap/docs/node.js/events

The docs explain the different event types such as CREATE, READ, UPDATE, DELETE, and custom events. However, CAP does not guarantee a fixed order of execution when multiple handlers (like CREATE and INSERT) are implemented for the same entity.

From practical experience, CREATE is the higher-level event that wraps the insert logic, and the order of execution you see is often due to how the handlers are registered in code, not a defined framework rule.

So the best practice is to use CREATE for general logic and reserve INSERT only for database-level customization.

Hi Eswar,

thanks for revised answer - I also went through this documentation already. 
As you noticed, there was no mention of 'INSERT' in the documentation and there is no guarantee of the sequence of execution.
