  The SAP error message SRT_WSP593 indicates that there is an issue with initializing a read-only instance of a destination in the SAP system. This error typically occurs in the context of web service communication, particularly when using the SAP Web Service Runtime (WSR).
  Cause:
  The error message can be caused by several factors, including:
  
  
  Incorrect Configuration: The destination specified in the error message may not be configured correctly in the SAP system. This could include incorrect parameters or missing settings.
  
  
  Read-Only Destination: The destination being accessed is marked as read-only, which means that it cannot be modified or initialized in the way that the operation requires.
  
  
  Authorization Issues: The user or service account attempting to access the destination may not have the necessary authorizations to perform the operation.
  
  
  Network Issues: There may be network connectivity issues preventing the SAP system from reaching the destination.
  
  
  Service Availability: The web service at the destination may be down or unavailable, leading to initialization failures.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Destination Configuration:
  
  Go to transaction SM59 (RFC Destinations) and verify the configuration of the destination mentioned in the error message.
  Ensure that the destination is set up correctly, including the connection type, target host, and service.
  
  
  
  Review Read-Only Settings:
  
  If the destination is intended to be read-only, ensure that the application logic is compatible with this setting. If it needs to be writable, consider changing the configuration.
  
  
  
  Check Authorizations:
  
  Verify that the user or service account has the necessary authorizations to access the destination. You may need to adjust roles or permissions.
  
  
  
  Test Connectivity:
  
  Use the Connection Test feature in transaction SM59 to check if the SAP system can successfully connect to the destination.
  
  
  
  Check Service Availability:
  
  Ensure that the web service at the destination is up and running. You can do this by trying to access the service endpoint directly (e.g., via a web browser or a tool like Postman).
