Hi,
I have an URL Mashup in C4C (Contact-> Marketing Permissions).
There I call https://sap...ID=ContactID
This mashup has the Parameter Binding Marketing Permission Port with InteractionContactID.

Now I want to implement the AccountID as new parameter. The new url will be https://sap...ID=AccountID-ContactID
How can I do that?
It's not possible to add a new parameter at Marketing Permission Port.
I tried to create a html mashup to access the CustomerID but it doesnt work. (sap.byd.mashup.context.inport.CustomerID). I couldn't access any parameter here. Is it possible to access the CustomerID with html coding?

New tab with binding of Marketing Permissions didn't work either. Here I create a BusinessObjectExtension, bind Marketing Permission, but then I didn't know how to do it.
Thanks for suggestions and help
