RACUST 11.5.10 Can we add a new site to an existing customer?

Hello Colleagues,

I'm building a customer interface programme, and want to understand if we can load a new customer site to an existing customer header. So in this example, the customer header exists and it has a site already. But now we want to attach a new site to the existing header.

Is this possible and what should the tables be populated with to make this work? I can see that the customer interface table has an insert_update_flag but I can't seem to separate out the Customer from its Sites.

Thanks for your help.

Regards
