1. Go to settings > checked this box and choose SAV pricelist (this pricelist should be created based on your setting) 

2. Create SO then adjust the price based on this principle: 
sol > product cost: take SOL

sol<product cost: sav price list 

For example:

1. I choose Apple liquid with price in SOL = 200 > cost price (=80) => take price from SOL  
2. I choose Cable Management Box (which category is all/seable/office furniture) with price in SOL =60 < cost (=90) => take price from SAV pricelist is 100 

3. Product "booking fees" as service product > which cant printed in proforma

3. Go to transfer > validate transfer > print forma > check the price 
- for apple liquid: it should be 200

- for cable management box: should be 100
