Z_BUS1006 partner change not triggered

Dear experts!

I copied BO BUS1006 into Z_BUS1006 and added two methods. BO is released and WF is developed. BUS1006 works fine, but Z_BUS1006 doesn*t trigger an event.

SWEL shows: BUS1006 message: No consumer registered.

SWE2 shows (Event linkage):

SWU0 shows:

I don't know, whats going wrong.

Thanks for any advice.
