Problem with tax exempt status and special tax status.
However this rule is not working the tax is calculated for these items. I again defined the same rule for standard tax status by selecting tax not applicability in rule. This rule worked as expected.
I believe as the standard tax status is defined as default tax status; the rule defined under this status is working as expected.
Can some help me why that rule defined under exempt status code is now working as expected? The same issue is appearing for special tax status.
