Custom field link question

I created a custom field in my “Customer” form. I need to add that custom field value to a quotation and probably to other transactions. In essence, I need to be able to “pass” the information of the custom fields I created to other forms and ideally make them appear with their default value

@wizard0207, You mean to say, you want to fetch this value on Quotation when you select respective Customer, right ? If Yes, refer this link -

Thank you very much. Where do I configure these values? Can I do it from the web interface?

You need to write custom script for respective doctype.
