Hello, 

I am trying to create a computed fields called x_remaining_qty, which calculates the difference between product_qty and the received_qty. 

Using studio:

created the field : 'x_remaining_qty' as decimal / float

added dependencies :  product_qty,received_qty 
Calculated Field: 
for record in self:

        record['x_studio_remaining_qty'] = record.product_qty - record.qty_received

the value is always 0.00 

I also tried to surround "x_studio_remaining_qty" with double quotes .. still not luck, 
can someone give me a little direction? 

Erich
