Global Container set Parameter

Hello,

I would like to change the field CONTENT_TYPE in my SOAP-Header-Message. Now I know that I can do this in the GlobalContainer inside the message-mapping with an user-define function.

I found in the SAP-help and in the SDN so many messages and examples how I can use the GET-Parameter method. But my problem is, to set a new CONTENT_TYPE-Parameter.

Maybe somebody can post me a few lines of coding, how I can do this.

Best regards,

Christoph
