I have created one sales order and from that order I have created 2 delivery notes and some sales invoice.
After clicking on Linked With icon in appframe-iconbar, this shows complite list of linked doctype.
We can find which delivery notes and sales invoice is created using Sales Order. Its a very good feature that ERPNext provide.
But when we click on linked with icon on Delivery Note it shows ‘Not Linked to any document’
I like to know working of this, please let me know if I am wrong.
