|
To pull a value of a link on selection, use the `add_fetch` method.
|
|
|
|
add_fetch(link_fieldname, source_fieldname, target_fieldname)
|
|
|
|
### Example
|
|
|
|
You create Custom Field **VAT ID** (`vat_id`) in **Customer** and **Sales Invoice** and want to make sure this value gets updated every time you select a Customer in a Sales Invoice.
|
|
|
|
Then in the Sales Invoice Custom Script, add this line:
|
|
|
|
cur_frm.add_fetch('customer','vat_id','vat_id')
|
|
|
|
