How to create custom field under Customers-> Orders-> Communication tab. Actually I’ve created one field in s_order table to store transaction details and I want to display transaction details under Communication tab, so it should reflect in frontend order history also. How to achive this…?
You should never extend the Core-tables, use the _attribute tables for your individual fields (that is their purpose), because otherwhise you might face some difficulties updaing shopware and using plugins.
