SAP Error Message - Details

• Message type: E = Error

• Message class: FKKINV - Invoicing in Contract Accounts Receivable and Payable

• Message number: 284

• Message text: Not possible to determine a unique invoicing currency

What causes this issue?

Normally, the invoicing document is created in the currency of the
<DS:DE.SRCDOCNO_KK>source documents</> being processed. In this
particular case, the system cannot uniquely determine the currency of
the invoicing document.

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?

You can invoice the contract account in dialog mode. To do so, start
invoicing in <DS:DE.INV_EXPERT_KK>expert mode</>. Either enter the
invoicing currency for the invoicing unit, or group together only source
documents with the same currency in an invoicing unit.
For automatic derivation of the invoicing currency (for example, in mass
processing for invoicing), you have two choices: either use event
<DS:FU.FKK_SAMPLE_2603>2603</>; or, select the rules for automatic
generation of invoicing units, so that entering source documents in an
invoicing unit is only allowed if the documents have the same currency.
