yes 6 is maintained for both tax types.
Actually i did a test likewise:
initial value for tax classification 3 for both tax types
initial value for tax indicator(purchasing) null
By mm17 i changed only tax classification to 6.
No changes made message is obtained.
However in the material master, the values has been changed to 2 for tax classification and tax indicator( although i did not change it by mm17)
What is the link between tax classification and tax indicator? How can i check the settings?
Why is it taking the values 2 by default?
