If the special price of an item is blank and the customer price level is a special price, then there is no price and it is displaying as the Nan on the site since no price.
Jira code: SQUIP-379
Requirement
To correct the price for the item which shows $NaN when the price column in the NetSuite account is blank.
Solution
Add a script that will load the item based on the internal. On loading the internal id of the item record is fetched to the script, then the item record loads and check if the price level is blank.
If the price level is blank we can add the price which is confirmed by the client.
Another solution is not to keep the price level blank.
Note: The client chose the second method. So the task was not done n this case.
