What rules would cause ""Not in IOList"" error on SO Order Lines object (called from ItemCode column Post_Validation.
I checked this by putting the SetValue immediately after the successful GetValue on the same Unit of Measure field.
retval=oBusObj.GetValue(""ItemType$"",sItemType)
retval = oBusObj.GetValue(""UnitOfMeasure"",sSalesUOM)
retval = oBusObj.SetValue(""UnitOfMeasure"",sSalesUOM) ! Returns ""Column is not in the IOList"" as LastErrorMsg
sMsg = "" Setting Unit of Measure - Last error was: "" & oBusObj.LastErrorMsg ' returns Column is not in the IOList - ?? that column used OK above in GetValue
retval = oSession.AsObject(oSession.UI).MessageBox("""",sMsg)
