[HaO] 2015-04-27: I am attacking the subject to write a more or less generic TCLWS [Web Service] client for SAP.
This is my "progress report page", which might involve the next days when I progress.

Thanks to Gerald W. Lester for the great package !

**Literature**

This is the book I am using for reference: [https://www.rheinwerk-verlag.de/sap-schnittstellenprogrammierung_3496/]

**Authentication**

SAP has many authentication and transport security options.
I tried HTTP Basic Authentication and no transport layer security.

Within this clt thread [https://groups.google.com/forum/#!topic/comp.lang.tcl/uOAhxCNPLwk], JMar wrote how to use basic authentication:


======tcl
#-- http basic authentication
set authinfo [ base64::encode $szUsername:$szPassword ]
set httpHeader [ list Authorization "Basic $authinfo" ]

set szResponseDct [ ::WS::Client::DoCall $szServiceName myMethod $myRequest $httpHeader ] 
======

This worked out of the box.


**WSDL File**

The WSDL file delivered by SAP parses out of the box.

**CALL**

The main Information is that SAP only supports WSDL 1.1 [https://en.wikipedia.org/wiki/Web_Services_Description_Language%|%Wikipedia WSDL%|%].
