SAP Error Message - Details

• Message type: E = Error

• Message class: FML_CUST - Message Class for ML Customizuing

• Message number: 010

• Message text: ML type &1 referencing FI or CO is not allowed

What causes this issue?

ML type &v1& references currency settings in FI or CO.

System Response

Using an ML type that references FI or CO is not allowed. Central FIN
ledger customizing allows you to set up more than three currency and
valuation types, but ML supports only a maximum of three. Therefore you
need to specify the currency and valuation types that are relevant for
the material ledger.

How to fix this error?

Use transaction OMX2 to define the currency and valuation types that are
relevant for the material ledger.
Use transaction OMX3 to assign this ML type to your valuation area.

Procedure for System Administrators
