How To Fix FKKZWF013 - Calculation type '01' and '02' can only be assigned to a valuation area.

FKKZWF013 - Overview

• Message type: E = Error

• Message class: FKKZWF - Doubtful Item Entry/Individual Value Adjustment

• Message number: 013

• Message text: Calculation type '01' and '02' can only be assigned to a valuation area.

What causes this issue?

Several posting areas &V1& were assigned with the tax calculation type
<LS>01</> (percentage: tax and revenue have equal status) and <LS>02</>
(amount-dependent: tax before revenue (USA only)). However, this
calculation type can only be allocated to a maximum of one valuation
area for each company code.
If necessary, tax adjustments are posted to the appropriate tax account
for both tax calculation types. As this tax account must be the same for
all ledger groups however, there cannot be different tax adjustments in
different ledger groups. However, this could happen if a receivables
item was individually adjusted differently in two valuation areas. The
tax to be adjusted could then be different in the two valuation areas.

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 which valuation area should receive the tax calculation type <LS>
01</> or <LS>02</> and allocate a different tax calculation type to the
other valuation areas.
