Price Level on the Customer Record is not followed

When Home> Set Preferences> Transactions tab> Basic section> Auto Fill Transactions = True.

The behaviour is that the information on transaction pages is automatically filled based on the last transaction for the entity chosen. That is the reason why the price level on the customer record is not followed.

Alternate Solution:

Set the Home> Set Preferences> Transactions tab> Basic section> Auto Fill Transactions = False. Create a Sales Order, add items for the customer and the price level for that customer record is followed.
