  The SAP error message SRT_WSP2752 indicates that there is a mismatch in the contract implementation references in a web service scenario. Specifically, it suggests that two different contracts are being referenced in a way that is not allowed or expected. Here’s a breakdown of the cause, potential solutions, and related information for this error:
  Cause:
  
  
  Contract Mismatch: The error occurs when a web service implementation is trying to reference two different contracts that are not compatible with each other. This can happen if:
  
  The service implementation is incorrectly configured to use multiple contracts.
  There are inconsistencies in the service definitions or configurations in the Service Registry.
  The service consumer and provider are not aligned in terms of the contracts they are using.
  
  
  
  Configuration Issues: There may be issues in the configuration of the service interfaces or the way they are defined in the SAP system.
  
  
  Solution:
  
  
  Check Contract Definitions: Review the contract definitions in the SAP system. Ensure that the contracts referenced in the implementation are consistent and correctly defined.
  
  
  Align Service Implementations: Make sure that the service implementation is aligned with the correct contract. If you have multiple implementations, ensure that they are all referencing the same contract.
  
  
  Update Service Registry: If there have been changes to the contracts or implementations, ensure that the Service Registry is updated accordingly. This may involve re-registering the services or updating the service definitions.
  
  
  Review Service Consumer: If you are consuming a service, ensure that the consumer is configured to use the correct contract that matches the provider's implementation.
  
  
  Check for Duplicates: Look for any duplicate or conflicting service definitions that might be causing the confusion in contract references.
  
  
  Testing: After making changes, test the service to ensure that the error is resolved and that the service behaves as expected.
