Solution for FS, 214

What causes this issue?

The G/L account requires a valid tax code.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the customizing settings to ensure that a corresponding tax code
is also determined and transferred when creating a line item for the
account.
You can also define two tax keys which mark the items as non-taxable for
transactions not relevant to tax.
If necessary, the G/L account can also be set so that the tax code is
not a required entry when posting transactions not relevant to tax.
