Triggering BO from Change document object..

Hi Experts,

I had a problem triggering custom Business object from custom Changed document object..

The scenario is like this...

' I had created a simple business object with key field as MATNR..

and a changed document in SCDO transaction.. I had also maintained the event linkage with the Changed document object in SWEC transaction and mode Is CHANGE...

The thing is if i change the existing material, then, my change document object has to trigger and in turn it should trigger my Business object....

This had happened if i use the standard changed document object 'MATERIAL' but not with custom changed document object'.

So i would be glad if any one help me how to trigger the custom Business object with the custom changed document object.

Any help would be appreciated.
