• What is the cause and solution for SAP error message ESH_SEARCH126 - Error for namespace &1: Only 'http', 'z' or 'y' are allowed at start ?

  The SAP error message ESH_SEARCH126 indicates that there is an issue with the namespace of a search service or a related configuration in the SAP Enterprise Search (SAP ESH) environment. Specifically, the error states that only namespaces starting with 'http', 'z', or 'y' are allowed. This typically means that the namespace you are trying to use does not conform to the expected format.
  Cause:
  
  Invalid Namespace: The namespace you are trying to use starts with a character or string that is not allowed. In SAP, namespaces are often used to differentiate between standard and custom objects.
  Configuration Error: There may be a misconfiguration in the settings related to the search service or the search connector.

  Solution:
  
  Check Namespace: Verify the namespace you are using. Ensure that it starts with 'http', 'z', or 'y'. If it starts with any other character, you will need to change it to comply with the allowed formats.
  Modify Configuration: If the namespace is part of a configuration file or a service definition, update it to use a valid namespace.
  Review Documentation: Consult the SAP documentation for Enterprise Search to understand the correct format and usage of namespaces.
