• What is the cause and solution for SAP error message SRT_CORE149 - No support for a de-isolated consumer to re-use an isolated sequence ?

  The SAP error message SRT_CORE149 indicates that there is an issue with the handling of isolated sequences in the context of web services or service-oriented architecture (SOA) within SAP systems. This error typically arises when a consumer (client) that has been de-isolated attempts to reuse an isolated sequence, which is not supported.
  Cause:
  
  
  Isolation of Sequences: In SAP's web service framework, sequences can be isolated for various reasons, such as ensuring that certain operations are executed in a specific order or to maintain state. When a consumer is de-isolated, it means that it is no longer operating in a controlled sequence context.
  
  
  Improper Sequence Management: The error can occur if the application logic attempts to reuse a sequence that was previously isolated, which is not allowed. This can happen due to incorrect handling of service calls or misconfiguration in the service definitions.
  
  
  Configuration Issues: There may be configuration settings in the SAP system that dictate how sequences are managed, and if these are not set correctly, it can lead to this error.
  
  
  Solution:
  
  
  Review Sequence Management: Check the application logic to ensure that sequences are being managed correctly. Ensure that isolated sequences are not being reused after a consumer has been de-isolated.
  
  
  Adjust Service Configuration: Review the configuration settings for the web services involved. Ensure that the settings for isolation and sequence handling are appropriate for your use case.
  
  
  Error Handling: Implement proper error handling in your application to manage situations where a consumer might attempt to reuse an isolated sequence. This can include checking the state of the consumer before making service calls.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the expected behavior regarding isolated sequences and how to configure them properly.
  
  
  SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They can provide insights based on the specific version and configuration of your SAP system.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide patches or updates that could resolve the issue.
  Web Service Configuration: Familiarize yourself with the configuration of web services in SAP, particularly regarding isolation and sequence management.
  Testing: Conduct thorough testing of your web service calls to ensure that sequences are being handled as expected, especially in scenarios involving multiple consumers or complex workflows.
  
  By addressing the underlying causes and ensuring proper configuration and handling of sequences, you can resolve the SRT_CORE149 error and improve the stability of your SAP web services.
