  The SAP error message CSP_ENTITY_CHECK026 indicates that there is an issue with the creation of an entity by composition due to an incorrect value for the ETag binding. This error typically occurs in the context of SAP Cloud Platform or SAP Fiori applications when working with OData services.
  Cause:
  The error is usually caused by one of the following reasons:
  
  
  Incorrect ETag Value: The ETag value provided in the request does not match the expected value for the entity being modified or created. This can happen if the entity has been modified since the ETag was retrieved.
  
  
  Concurrency Issues: If multiple users or processes are trying to modify the same entity simultaneously, the ETag may become outdated, leading to this error.
  
  
  Improper Binding: The ETag might not be correctly bound in the application code, leading to the wrong value being sent in the request.
  
  
  Service Configuration Issues: There may be issues with the OData service configuration that affect how ETags are handled.
  
  
  Solution:
  To resolve the CSP_ENTITY_CHECK026 error, you can take the following steps:
  
  
  Check ETag Value: Ensure that the ETag value being sent in the request matches the current ETag of the entity. You may need to retrieve the latest ETag from the server before making the create or update request.
  
  
  Refresh Data: If you suspect that the data has changed, refresh the data in your application to get the latest version of the entity and its ETag.
  
  
  Review Application Logic: Check the application code to ensure that the ETag is being correctly bound and sent in the request. Make sure that the ETag is being updated appropriately when the entity is modified.
  
  
  Handle Concurrency: Implement proper concurrency control in your application to handle scenarios where multiple users might be trying to modify the same entity.
  
  
  Check Service Configuration: Review the OData service configuration to ensure that ETags are being handled correctly. This may involve checking the service metadata and ensuring that the ETag is being generated and returned as expected.
  
  
  Debugging: Use debugging tools to trace the request and response cycle to identify where the ETag mismatch is occurring.
  
  
  Related Information:
