How to call Business Service or Workflow from PM script in Siebel Open UI

There is plenty documentation how to call business service or workflow from Siebel Open UI PM or PR script. In old siebel the call was as simple as from browser java script. There are undocumented workarounds to make it work in Siebel Open UI.

There are needed  few steps :

1. Generate PM script for your applet for example from https://duncanford.github.io/prpm-code-generator/?prpm=PM&object=DesktopList&name=BeautifulThing&userprops=&comments=Yes&logging=No

2. Insert the listener in the superclass.Init.apply method: this.AddMethod("InvokeMethod", PreInvokeMethod,{sequence : true,scope: this});    }

3. Insert the code which implements the call of BS or Workflow, where methodName is the call from button : function PreInvokeMethod(methodName, psInputArgs, lp, returnStructure) { 

4. To retrieve the result use : var psResult = psOut.GetChildByType("ResultSet"); 

5. To CancelOperation , here is the trick , use : returnStructure ["CancelOperation"] = true; SiebelApp.S_App.uiStatus.Free();

  Full code of the PM script for the Access Controlled Business Service List Applet is here :
