Read workitem Container Value in Terminating event Check Function Module

Question

Hi
I have some problems reading work item data / values of a work item container element in a check function module on a terminating event – Do any of you know if this is possible, and if so, how it’s done ?
In My scenario I have created a multiline approval step for my business document, one task pr Line Owner.  The Event Approved is defined as a terminating event for this task, and the line owner is passed to the task container.
Now, when I raise the event, with the line owner as an event parameter, I would like to check if the line owner on the raised event, matches the line owner in the task container in question in a check fm. But here I faced the problem, that only event data, and not work item data, are passed to the Check Function module.

Hello Morten, hello Arghadip,
in the instance linkage's check function module (entered via transaction SWEINST) you'll have the workitem-id in the system event parameter EVTRECEIVER_ID
With this number you can use the frame work in order to read the work item container.
This is a sample coding, how you access the correct work item container using SAP Enterprise and it's new OO frame work, which checks on the terminating event of BUS2105.Released the correct release code for a work item.
INCLUDE <cntn01>.
INCLUDE <SWFCNTN01>.
INCLUDE RSWEINCL.
