How to carry forward same child table from quotion to sales order to sales invoice?

I have customized and created a quotation-item child table and want to carry forward the same table (with same columns and data) to sales order and sales invoice.

When I create SO from quotation, only the following columns are fetched not all data -

and after creating sales invoice, following cols are fetched -

I need the complete child table to make final invoice from quotation-item child table like -

Kindly help !!

If same table name and same fieldname with all doctype then automatically fetch the data without the code.

Automatically fetch is done in quotation but when from quotation to sales order all the data is taken I can not write code and fetch data, also I am asking that when we create sales invoice from sales order the data is automatically fetched but only above cols are fetches where i want all the cols to be fetched.
