  The SAP error message ISU_UMC_ODATA008 indicates that a required key attribute is missing when trying to retrieve an entity set via OData. This typically occurs in the context of SAP IS-U (Utilities) when working with OData services.
  Cause:
  The error is triggered when a request is made to an OData service, but one or more key attributes that are necessary to identify the entity set are not provided in the request. Each entity in an OData service is usually identified by a unique key or combination of keys, and if these keys are not included in the request, the service cannot process it.
  Solution:
  To resolve this error, you should:
  
  
  Check the OData Request: Review the OData request being sent to the service. Ensure that all required key attributes are included in the request URL. For example, if you are trying to access a specific entity, the URL should look something like this:
  /EntitySet(KeyAttribute1='value1', KeyAttribute2='value2')
  
  
  Refer to the Service Metadata: Use the OData service's metadata (usually accessible via a URL ending in $metadata) to identify the required key attributes for the entity set you are trying to access. This will help you understand which attributes are mandatory.
  
  
  Validate Input Parameters: If the request is being generated programmatically, ensure that the code correctly populates all necessary key attributes before making the request.
  
  
  Check for Typos: Ensure that there are no typographical errors in the key attribute names or values.
  
  
  Consult Documentation: Review the relevant SAP documentation or OData service documentation for any specific requirements or examples related to the entity set you are working with.
