Const.PM_DataItemLovUserSelectDistinct
The framework sends the Const.PM_DataItemLovUserReturnSelectDistinct message to a data item to establish if the search should be run using a distinct selection.
Name | Description |
---|---|
wParam | Unused |
lParam | Unused |
The framework will by default not run a distinct selection in LOV dialogs.
A LOV reference that defines only a limited amount of parent keys can use this
message, making the result only showing unique rows. Still, the design in such
places is limited, since LOV references should normally always define and
provide all the parent keys needed, for why the message
PM_DataItemLovUserReturnSelectDistinct should only be used when database changes
where defining additional LOV views is for some reason not possible.
NOTE! A distinct selection have bad impact on performance, making the
search run much slower.
switch (e.ActionType) { case Ifs.Fnd.ApplicationForms.Const.PM_DataItemLovUserSelectDistinct: e.Handled = true; e.Return = true; return; }
Return true if the LOV search should be executed using a distinct selection.
