How To Fix ACC_SYSTEM040 - No unique reference accounting system for accounting system &1

SAP Error Message - Details

• Message type: E = Error

• Message class: ACC_SYSTEM - Messages in Package FINB_ACCOUNTING_SYSTEM

• Message number: 040

• Message text: No unique reference accounting system for accounting system &1

What causes this issue?

Accounting systems &V2& and &V3& were determined as reference accounting
systems for accounting system &V1& in the present context (for example,
for a document) by applying reference valuation rule &V4&.
But the reference accounting system must always be able to be determined
uniquely for a given accounting system in an existing context.
The cause of the problem is that at least two accounting systems are
determined for the context, and that both of these accounting systems
occur as reference accounting systems in the valuation rule.

System Response

Processing is terminated.

How to fix this error?

Check the settings of reference valuation rule &V4& and the selection
conditions for accounting systems &V2& and &V3&. Either restrict the
selection conditions so that only <ZH>one</> accounting system can be
found for the context, or remove one of the accounting systems from
reference valuation rule &V4&.
If you cannot find any errors, then the context information transferred
during processing is not sufficient to determine one reference
accounting system. In this case, inform your system administrator.

Procedure for System Administrators
