You can't enter a tax amount in this item since, due to the posting
amount entered and the tax code, a total tax amount of zero has been
calculated.
This could either be due to the fact that the tax code has been defined
with a value of 0%, or because the posting amount entered (that is, the
tax base) is too small.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Only enter tax amounts in conjunction with tax codes for which a
percentage rate not equal to zero has been defined. Make sure that in
documents with several G/L account items you enter the total tax amount
in an item with a sufficiently high posting amount.
