Tax Classification code getting cleared after program "Requisition Import Program" completes for ext

Hi All,

We are facing issues while entering tax classification code in sales order line.

As per our rules, tax classification code needs not to be taken care of. All tax will be calculated using tax rules.

But there is one exception case, where user need to provide tax classification code and using tax rules, we will default some other rate.

Tax rules are working fine till the time tax classification code is there. But we are facing issues after booking sales order and also after booking when we ran "Requisition
Import Program" program.

TCC getting cleared after booking is known issue in Oracle. So we will take care TCC after booking sales order.
