  Solution:
  
  Review Defined Interfaces: Check the interfaces that are currently defined for the OData service in question. You can do this by navigating to the AIF configuration in the SAP system.
  Consolidate Interfaces: If there are multiple interfaces that serve similar purposes, consider consolidating them into fewer interfaces to reduce the total count.
  Adjust Configuration: If necessary, adjust the configuration settings in AIF to allow for a higher number of interfaces, if that is appropriate for your use case.
  Check for Duplicates: Ensure that there are no duplicate interfaces defined for the same service, as this can contribute to the error.
  Consult Documentation: Refer to the SAP documentation for AIF and OData services to understand the best practices and limitations regarding interface definitions.
  Contact SAP Support: If the issue persists after reviewing and adjusting the configurations, consider reaching out to SAP support for further assistance.
