BPM Task Execution: Custom Action for Cancel of a running process Task

[Former Member]

Hi Experts

I need to implement a solution for a Client requirement: Every user who has a new Task in his UWL should be able to cancel that by a custom Action named "Cancel running Task". To do that, the user should click on the Task Link in his UWL, the Task will be shown, and he can select the "Cancel running Task" from the Actions menu context.

From my point of view, the two steps are required:

1) Add a custom action ("Delete running Task") in the Actions context menu of SAP BPM Task UI Execution. Hereto my Question: How can I add a custom action context item on SAP NetWeaver Administration --> Configuration --> Infrastructure --> Application Module --> Module List (tc~bpem~wdui~taskinstance) / Web-Module-Details (xxxx.taskexecution: TaskExecution/settings) / Properties?

2) Call a BPM API function which executes the cancel process. But also I couldn't found a POST to do that. I just have seen those to complete, but not to cancel.

Thanks to all for help

Best Regards
