Item custom field in Invoice

I think my query has been asked before.

Copy a custom field data into another document

Hi, I have added an custom field called maintenance_fee into Item table. I want the data of this field to go automatically into the Sales Order Item when I select the item in a Sales Order. I have added a field with the same name (maintenance_fee) in Sales Order Item table, but I am not sure what to do in order to copy the field from the Item table when someone select the item in the Sales Order.

To add a custom field in item & get the same custom field in invoice,

1. Create the Custom Field “abc” under Doc Type Item
2. Create the Custom Field “abc” under Doc Type “Sales Order Item”
3. Create the Custom Script under doc type “Sales Order” (Note that it has to be created under “Sales Order”) cur_frm.add_fetch(‘item’, ‘abc’, ‘abc’)

And yet, it doesnt work!!
