issue while adding event in SWEC 'field restriction'

Hi All,

I am facing the below issue  -

On changing the order from IW32 ( requirement quantity field), a new workflow should be triggered. For any change to this field, a workflow should be triggered.

Now I checked the trace, but found that there is no event triggered for the same. Now I have created a new event in custom bor object ZBUS2007 -

Event Name  - BUS2007.QuantityChanged. and used the parameter in this event as shown in the screenshot.

Also, I have maintained this event in the Start events of the workflow and completed the binding. My event is active ( green) now. Also, in swetypv, the event linkage is checked.

Now I am trying to add a new entry for this event in SWEC - on change. When i do the same, and go in the field restrictions tab, it is giving the error - Table RESBD not used for change document object ORDER.

What should I do here ?

Regards
