Allow Tax Applicability option at Supplier/Site level

Hello,

Our client upgraded from 11i to 12.0.6 and then from 12.0.6 to 12.1.3. We are trying to cleanup the tax setup options for all the suppliers. We want to set 'Allow Tax Applicability' to Yes for all the suppliers and sites.

This information is available in the supplier tables(ap_suppliers/ap_supplier_sites_all) as well as in zx_party_tax_profile. We would like to know which setup data (Zx or AP) is considered while calculating tax?

Supplier site table has a value of 'L' for Allow Tax applicability whereas Zx has a value of Y.

Let us know which is the right table to consider for this cleanup and update these fields if necessary
