In the Audit History 2025, there is a column named "Taxable" that just says "Yes" or "No" that is between "Class" and "Billable".

1- What is the logic for lines with transaction when we see for the Taxable column  "Yes" and "No"?

Also for these scenarios :

a) For the same supplier but on different bills that has taxes, why sometimes its "No", and sometimes its "Yes" for the same kind of transaction ?

b) Within the same bills for a taxable supplier, there is a Yes for one line and then a No for another lines when both have amounts that should be taxable. Why?

c) For the same bill, sometimes we see a No and when we have imported some data to overwrites it as a Yes. Why?

2- What does it do in the back end, the "Yes" and "No" for the taxable line?

Thank you
