Access Sequence is not working-Sales order tax calculation

Hi Gurus,

I am seeking some piece of advice from you all.I am testing India sales tax configuration and everything was working and tax calculation was correct in the sales order until something goes wrong in config.

The issue is I created a sales condition type ZWIG for India Integrated GST.When I create a sales order I don't see this condition type ZWIG coming in the sales order.The analysis explains "Access is not made" and condition record does not exist.There are two exclamation marks for Customer/Material tax classifications.

I checked all my config, everything is defined correctly.So after checking all the forums online for the same issue, I could not find any solution that resolve my issue.

As a last resort, I deleted all the access sequence in V/07 for ZWIG and redefined it.Its still not working. Do I need to do anything additional to generate the access sequence?.I be really grateful for any suggestions.Thanks
