I want to filter the items form so that it does not display Obsolete items. I noticed that the Permanent Filter Expression filter is set to V(FliterByQueryParmVar) on the SLItems collection for this form. When I look at this, it does not appear that anything is passed to this variable. If I try to just add "AND Stat <>'O' after this, I get an error that AND is not valid. Anyone know what drives this filter? I do not see anything in Form Script. I would like to understand before I just remove it and add the filter I want.
