Hi Osman,

In order to get field value from sale order line to stock picking, you have to follow these steps:

1) First you have to find the method or code that create stock move record in sale order line.

2) From there you can pass that two fields in context in that method (using with_context)

3) Now, override or go to create method of stock move in that you will receive that two fields

4) So here you can do any operation to pass that field to stock picking or any else.

Hope it will useful for you..
