Hi Cornelia,
I was logged on query designer while I was creating conversion rule but I already tried logging off and it didn't work.
Here are some screen shoots how my selections look. First one is from the query where I don't see conversion, and second one is where I use it. Never mind the fact that I'm using DEB_CRE_LC in first case, it's the same thing when i swap it with DEB_CRE_DC. One other strange thing is that in conversion selection dropdown list, my conversion has only technical name...
Regards,
