Unable to Read Workflow Container Values

Hello,

I need to read the Workflow Container values in my method of z business object. when i click on the work item in the SAP inbox the code SWC_GET_ELEMENT CONTAINER 'LEVEL' LEVEL. works fine in the method and give the value of container(LEVEL), but when i click on the Link under Objects & Attachments, the container table does not contains any value. so I could not get the value i am looking for.

thanks & Regards

Mohit
