  The SAP error message SADL_GW_CUD_CONTR024 indicates that there is an unexpected amount of key fields in a request when using the SAP Data Access Layer (SADL) for Create, Update, or Delete (CUD) operations. This error typically arises when the system expects a certain number of key fields to be present in the request, but the actual number provided does not match the expectation.
  Cause:
  
  
  Mismatch in Key Fields: The most common cause of this error is that the request being sent to the SAP system does not contain the correct number of key fields that are defined in the data model. This can happen if:
  
  The request is missing required key fields.
  There are extra key fields included that are not defined in the data model.
  The key fields are incorrectly defined in the service or data model.
  
  
  
  Service Definition Issues: If the OData service or the underlying data model has been modified (e.g., fields added or removed), it may lead to inconsistencies between the expected and actual key fields.
  
  
  Incorrect Mapping: If there is a mapping issue between the frontend application and the backend service, it may lead to incorrect key fields being sent.
  
  
  Solution:
  
  
  Check the Data Model: Review the data model definition to ensure that the correct key fields are defined. Make sure that the number of key fields in the request matches what is defined in the model.
  
  
  Validate the Request: Inspect the request being sent to the SAP system. Ensure that:
  
  All required key fields are included.

  The values for the key fields are correctly formatted and valid.
  
  
  
  Update OData Service: If there have been changes to the data model, ensure that the OData service is updated and regenerated to reflect those changes.
  
  
  Debugging: Use transaction codes like /IWFND/ERROR_LOG or /IWFND/DEBUG to analyze the error logs and debug the request to identify the exact cause of the mismatch.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific OData service you are using to understand the expected structure of the request.
