Integration Framework, Intercompany and SEVT table

Hello

I am currently usin SBO 9.0 PL15, Integration Framework, an Intercompany. Everything works but i have a situation. I see that a SEVT table is being fill by lines with ObjectType =12 ( related to the OUSRtable ). I checked the evensender filter and Objecttype 12 is not one in the event filter.

How can I stop the SEVT table from filling up with lines with objecttype=12 ?

Regards
