/IWBEP/MC_SB_DPC_ADM027 - Details

• The SAP error message /IWBEP/MC_SB_DPC_ADM027 indicates that there is an issue with the specified interface in the context of an OData service. Specifically, the error states that the interface you are trying to use is a class, which is not valid in this context. This typically occurs when there is a mismatch in the expected type of the interface being referenced.
  
  Cause:
  
  Incorrect Interface Type: The specified interface is defined as a class rather than an interface. In SAP, OData services expect interfaces to be defined in a certain way, and if a class is provided instead, it leads to this error.
  
  Configuration Issues: There may be misconfigurations in the OData service or the associated data provider class (DPC) that are causing the system to reference a class instead of an interface.
  Development Errors: If the OData service was custom-developed, there may be errors in the implementation where a class was mistakenly used instead
