Product based setups

Hi All,

we have a client based in  ME. client want setup based on item. there are three rates 1. standard, 2. zero rated and 3 exempt. and situation is out of total item 95 % goods are covered in standard  rate. so we decide standard rated item will covered by default rate and for rest we will set rules. we set expert rules for exempt rated item based on the following Doc ID 1107666.1. and rule is set on Tax rate at rule tab still when we test this in Accounts receivable, its taking standard rate.

please suggest or help me in this.
