Running Acumatica import scenario from code - import

Question

How to run select "Import by Scenario" scenario -> press "Prepare&Import" from code?
I have tried this:
var importGraph = PX.Data.PXGraph.CreateInstance<SYImportProcessSingle>();
SYMappingActive mapactive = PXSelect<SYMappingActive>.Search<SYMappingActive.mappingID>(importGraph, importproviderID);
importGraph.PrepareImport.PressButton();
but this did not work to run "Prepare & Import" for "import by scenario" graph for my DAC.

Answer 1

First thing to check. Can you execute the import scenario from the application instance? I refer to the Process Import Scenario screen (SM206036). The provider error could be that the import scenario has no data provider assigned, or the provider is not usable.

Answer 2

Here is example how you can do it. I have written this for SalesOrder but you can modify it for any other screen. Also if there exist more than one Import Scenario for the same screen this code will use first Active one.
public class SOOrderEntry_Extension : PXGraphExtension<SOOrderEntry>
{
#region Actions
public PXAction<SOOrder> RunScenario;
[PXButton(CommitChanges = true)]
[PXUIField(DisplayName = "RUN")]
protected void runScenario()
{
var importGraph = PXGraph.CreateInstance<SYImportProcessSingle>();
var myMapping = PXSelect<SYMapping, Where<SYMapping.screenID, Equal<Required<SYMapping.screenID>>>>.Select(importGraph, Base.Accessinfo.ScreenID.Replace(".", string.Empty));
if (myMapping.Any())
{
importGraph.MappingsSingle.Current = importGraph.MappingsSingle.Search<SYMappingActive.name>(((SYMapping)myMapping.First(x => ((SYMapping)x).IsActive ?? false)).Name);
importGraph.Prepare.Press();
PXLongOperation.WaitCompletion(importGraph.UID);
importGraph.Clear(PXClearOption.ClearAll);
importGraph.MappingsSingle.Current = importGraph.MappingsSingle.Search<SYMappingActive.name>(((SYMapping)myMapping.First(x => ((SYMapping)x).IsActive ?? false)).Name);
importGraph.Import.Press();
PXLongOperation.WaitCompletion(importGraph.UID);
}
}
#endregion
}
