• What is the cause and solution for SAP error message STREX158 - ====> Set "&1" to HTTP header "&2". ?

  The SAP error message STREX158, which states "Set '&1' to HTTP header '&2'", typically occurs in the context of SAP systems that are interacting with web services or HTTP-based communications. This error indicates that a specific HTTP header needs to be set to a particular value, but it has not been configured correctly.
  Cause:
  
  Missing HTTP Header Configuration: The required HTTP header is not set in the HTTP request being sent from the SAP system.
  Incorrect Value: The value that is supposed to be assigned to the HTTP header is either missing or incorrect.
  Authorization Issues: Sometimes, the error can arise due to insufficient permissions to set the required HTTP headers.
  Configuration Issues: There may be issues in the configuration of the web service or the HTTP connection settings in the SAP system.
  
  Solution:
  
  
  Check HTTP Header Configuration:
  
  Review the configuration of the HTTP connection in the SAP system. Ensure that the required HTTP headers are correctly defined.

  Set the Required Header:

  Check Authorization:
  
  Ensure that the user or service account being used to make the HTTP request has the necessary authorizations to set the HTTP headers.
  
  
  
  Debugging:
