Release Indicator value is not passed in WF

Hi,

I want to trigger the wf when service entry sheet created. I created new workflow and using the BO Bus2091 for triggering. The user can Release/Reject. When he releases the field KZABN in the table ESSR sets the value X. I need to get the value from this table and pass to my wf. So i created an attribute and binded with my wf. After he releases, it shows empty value only but in table it is marked as X.

For testing i checked with another field, the value is passed for that field and i'm getting in my wf.

I want to know whether we can pass value of Release Indicator to WF.?

Can anyone help ??
