The Tax Classification re-Defaulted or Cleared When the Transaction Information Is Changed (Doc ID 7

Is there any way to override such behavior?

working instance: R12.1.3.

I have business case where end users:

- change manually tax code

- enter changes on the memo line

Outcome:

- vat tax code is re-defaulted

What end users expects:

- tax code stays "as is". the code should not change the value.

It would be great if there is profile value to do it.

One suggestion which I already got is to use eBTax: Allow Override of Tax Classification Code (set to yes). But this is not what i need. This profile option only handles if code is applicable for manual change and it can be done.
