• What is the cause and solution for SAP error message /IWBEP/CM_V4_APPS050 - Value of '&1' for $$skiptoken is not supported ?

  The SAP error message /IWBEP/CM_V4_APPS050 Value of '&1' for $$skiptoken is not supported typically occurs in the context of OData services when using pagination with the $skiptoken query option. This error indicates that the value provided for the $skiptoken parameter is not valid or not supported by the OData service.
  Cause:
  
  Invalid Skip Token Value: The value provided for the $skiptoken parameter may not correspond to a valid state in the dataset. This can happen if the token is malformed or if it references a position that no longer exists due to changes in the underlying data.
  Service Configuration: The OData service may not be configured to support skip tokens, or there may be limitations on the types of queries that can be executed.
  Data Changes: If the data in the underlying database has changed (e.g., records have been added or deleted), the skip token may no longer be valid.
  Versioning Issues: There may be compatibility issues between the client and the server regarding the OData version being used.
  
  Solution:
  
  Check the Skip Token Value: Ensure that the value being passed for the $skiptoken is correct and corresponds to a valid state in the dataset. If necessary, regenerate the skip token.
  Review Service Documentation: Check the documentation for the OData service to confirm that it supports the $skiptoken parameter and understand any limitations or requirements.
  Update the Service: If you have control over the OData service, ensure that it is properly configured to handle pagination and skip tokens.
  Handle Data Changes: If the underlying data is changing frequently, consider implementing a mechanism to refresh or regenerate the skip token based on the current state of the data.
  Test with Different Queries: Try executing simpler queries without the $skiptoken to ensure that the service is functioning correctly and to isolate the issue.
  
  Related Information:
