Default Tax Rate/Area Enter Purchase Order Not Update Automatically When Supplier Code Updated

Hi Experts,

This case occured when users changed the supplier code Using P4310 Enter Purchase Order,

When users change the supplier code (from supplier which no tax to supplier with tax), why the Tax Expl Code and Tax Rate/Area field doesn't updated automatically (fetch from F0401)? These fields still blank value after supplier code was updated.

Users are enforced to update manually the Tax Expl Code and Tax Rate/Area field.

It's take some risk because sometimes users forget to check these field and the amount/payment gone wrong

Any idea? Why JDE don't updated it automatically?

Sincerely,
