The "Company" master and "Customer" master have a "Tax Rounding Method" field for tax rounding settings.

I think the "Tax Rounding Method" in the "Customer" master is used for the "Tax Rounding Method" of the tax amount in the "Customer Invoice".

Which IFS movement does the "Company"master " and "Customer" master Tax Rounding Method" control?

I could not find a description in the IFS9 online documentation.
Since it is not mentioned, I cannot determine which setting is valid for my operation. Please let me know.
