Workprotect feature for R/3 or SEM backend systems

Question

Hi All,
I think the workprotect mode within the portal can be used only for CRM backend systems...
We have R/3 transaction iViews and SEM transaction iViews written in BSP's and want to implement workprotect feature for all these transaction iViews...
I would appreciate if anyone of you can post the sample piece of code to implement this feature.
Thank you

Hi,
Workprotect mode is a feature of the portal framework which can be used via javascript API by the applications which are running in the portal. This javascript API is the EPCM file.
If you want to use the workprotect mode of the portal you have to define a variable in your javascript which will hold the status of the dirtyFlag.
var dirtyFlag = false;
Take care that the variable will not be disappear with the next roundtrip.
Now tell the portal that you will take part of the workprotect mode by subscribing to a special event of the portal.
epcm.subscribeEventReliable("urn:com.sapportals.portal:workprotect","inquiryProtection",window,"my_protectionHandler");
Now define a javascript function:
function my_protectionHandler( event ){
    return dirtyFlag;
What will happen:
You have subscribed to an portal event which will be thrown when the user will navigate. In order that the portal knows which javascript function it must call to the your dirtyFlag you tell him the name of your function, ie. my_protectionHandler.
The only thing is now that you have to set the dirtyFlag depending on your business.
This is the workprotect function for portals since 6.0.
Hope this brief explanation will helps. 
with best regards
