• Message text: Tax category tax account wrong &1 &2 &3

What causes this issue?

You are using account keys for input- (tax type '2', technical field
T007B-STGRP) and output tax (tax type '1'). The account key is not
defined as an account key for non-deductible input tax (technical field
T007B-STAZF is initial).
The G/L account used for this tax posting has not been defined
accordingly, that is, the G/L account should be defined for input tax
with tax category '<(><<)>' (tax type '2') and for output tax with tax
category '>' (tax type '1'). Unless this is defined, this error message
is triggered.

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?

Correct the tax category of the <DS:TRAN.FS03>G/L account</> or, if
required, change the definition of the <DS:TRAN.OB40>account key</>. If
you have defined the same G/L accounts for input-and output tax, we
recommend that you create separate G/L accounts for input-and output tax
and to use the appropriate tax category for them.

Procedure for System Administrators

You can reinforce, weaken, or even switch off the error message by using
<DS:TRAN.SM30>Customizing V_T100C</> or the enhancement spot
'FI_TAX_CUSTOMIZED_MESSAGE' by using transaction SE18 if you do not use
the Cloud solution. We recommend that you do not switch off error
messages but correct the settings or the G/L accounts affected, and
reinforce the error messages to create correct postings. Please check
SAP Note 2770508, which provides a report for analysis and correction of
the G/L accounts affected.
Unless you correct the G/L accounts, you may be creating postings that
are incorrect and cannot be processed further, which is not the
responsibility of SAP.
This error message is only issued precisely once for each transaction
unless the corresponding error message is defined as message type 'E?.
