OrderBy in PXProjection Select does not work - acumatica

Question

Have any of you experienced this issue in Acumatica?
Adding OrderBy to Select2 in PXProjection attribute has no effect.
I checked the SQL query in Request Profiler and the data is sorted by key fields of the DAC.

Answer 1

Try adding your OrderBy to the PXSelect which is using the DAC made with the PXProjection. Note that by default, the records are ordered by the DAC keys.

Answer 2

In almost every case Acumatica will sort by the key fields first, so if your expectation was to have the data sorted exactly as in your OrderBy<> criteria then this won't work. What you can do instead of override the order directly in the view delegate, like this:
PXView select = new PXView(Base, true, this.myView.View.BqlSelect);
select.OrderByNew<OrderBy<Desc<MyDac.myField1, Desc<MyDac.myField2>>>>();
//<rest logic to select from the view>
This will always replace the order with your custom sort order. If you only want to do it only when the user hasn't altered the sort order in a grid, you can add a condition like that:
if (PXView.SortColumns.Length == this.myView.Cache.Keys.Length)
{
// apply custom default sort order
select.OrderByNew<OrderBy<Desc<MyDac.myField1, Desc<MyDac.myField2>>>>();
}
