If there is a RelationalExpr, you may see records which don't match "disappear", similarly if any 'Set Filter' coding is executed you may have records "disappear". So far, I have been unable to duplicate your problem. Please look at these limits to what is shown, as they could exhibit the kind of problem you describe. -- for instance, is there a MasterTable, perhaps linked by a key value?
