Question/Problem 

I want to create a custom SKU in order to account for some costs (non stock) from UK suppliers. How can I associate a non controlled SKU with a Purchase nominal account?

Resolution/Solution 

In order to use a Purchase nominal for a stock item you need to set the Purchase nominal in the accounts field of the stock item record.

Steps 

1. Go to Stock Item.
   
2. Click Edit.
   
3. Under Accounts heading, Purchase Nominal, select the Nominal from drop down. 
   
1. In order to do this the Purchase Nominal option needs to already exist on the system How To Create a New Nominal Account, and the Nominal must be set to System Type Purchase and Account Type Stock Type/Item.
4. Click the Options tab.
   
5. Under Advanced heading enable the CoS Excluded toggle
   
6. Save the Stock Item
   

Notes/Caveats 

Unless the CoS Excluded toggle is enabled, the Purchase Nominal will not be used.
