Return of URL parameters will change %26 back to &, and hence making the parameter useless

Method IF_HTTP_ENTITY~GET_HEADER_FIELD is called to fetch the URL with passing parameters, below logic executes to fetch it:

system-call ict

    did

      ihttp_scid_get_header_field

    parameters

      m_c_msg                            " > c handle

      name                               " > header field name

      value                              " < header field value

      m_last_error.                      " < return code

here value parameter fetch the url link, link with special character '&' should fetch with Hex value 26, but its not converting so link is not working,

Refer below example:

URL: https://XXXXXXXXXXXX/sap/bc/webdynpro/sap/XXXXXXXXXXXXXXX?sap-language=en&component_ty=FIN&component_id=TEST+D%26W+MU

for above link result of value parameter in above system-call statement is https://XXXXXXXXXXXX/sap/bc/webdynpro/sap/XXXXXXXXXXXXXXX?sap-language=en&component_ty=FIN&component_id=TEST+D&W+MU

D%26W --> D&W, due to this url is not working. does this related to any system setting, please provide your valuable input.
