AP Invoices Migation and Automatic Tax Calculation - R12

Hi,

We are doing migration of AP invoice and we don't want the system to automatically calculate the tax for the migrated invoices.

We want to automatically calculate taxes for new invoices entered in the system.

In 11i there was an option to allow/disable the automatic tax calculation that I cannot find in R12.

What is the alternative in R12? We are sending manual tax lines for the migrated invoices (associated to a particular Tax Classification Code).

Is the alternative to setup the interface column CALC_TAX_DURING_IMPORT_FLAG to 'N'??

We know we have the 'Calculate Tax' field at Supplier Level but if set this to NO once the migration is done we need to go to each supplier and update this option to YES.
