Quick Create with Reference

Hi Experts,

I would like to ask if there is any document / any way to create a custom business object with reference.

E.g. In AccountTI, I created an EC which contains a Table of my CustomBO.

[AlternativeKey] element ID                     :ID;                              

                               element CustomerID  :BusinessPartnerInternalID;

etc.

In this EC, there is a button "New CustomBO" and it calls the Quick Create of CustomBO.

I would like to fetch the data from AccountTI (AccountID) to CustomerBO.CustomerID so that whenever I click on the new button in EC, the CustomerID is set as default.

Many thanks for your help

Best regards

Linh
