I want to make a custom field and the functionality of that field with the custom app, How can i do that without change the erpnext code only using custom app ?
Currently i added search customer by email using customize form but it will change the code in erpnext, I want to make it from my custom app how to achieve that ?
The changes will definitely change code in erpnext app. However, if you wish to ship your changes use the hooks to add fixtures and export.
Can you give a example of it or any reference ?
i want to make it those changes from my custom app like add search customer by email field and when someone give the email address then customer field will be automatically fetch that customer or throw error like no customer exists for this email address.
