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?

Please enter an IRF Data Mapping class, which implements Interface
'IF_CFD_IRF_MAPPING' and which can be instantiated publicly. A possible
CONSTRUCTOR must not have any mandatory parameters.
In this class you need to map the requested values (sign, option, low
value, high value) to the key values in the Association Target.
The mapping class will be instantiated and used within the Extensibility
Framework, e.g. to do the Information Retrieval with the mapped values
within Custom Business Objects, where the Association Target is used.
If appropriate, you may also use your IRF Data Mapping class for your
standard mapping within the called function modules of IRF BAdI
'BADI_DTINF_READ_API_EXT' (Enhancement Spot ES_DTINF).
