DIXF recurring file imports fail for data packages. What now?

Applicable to all AX7 releases.

If you are following https://ax.help.dynamics.com/en/wiki/recurring-integrations/ to setup your recurring imports, and if you are trying to use a data package with multiple entities, you may notice that the server shows a “preprocessing failure”. This is a bug. Until this is fixed, a workaround is to over-layer the ApplicationFoundation:

Create a new class:

class DMFSchedulerStatusUpdate
{
    using Microsoft.Dynamics.AX.Framework.Tools.DataManagement.Serialization;
    [DataEventHandler(tableStr(Batch), DataEventType::Updated)]
    public static void Batch_onUpdated(Common sender, DataEventArgs e)
    {
        Batch task = sender;
        if(task.Status == BatchStatus::Finished || task.Status == BatchStatus::Error && task.ClassNumber == className2Id(identifierStr(DMFImportTaskScheduler)))
        {
            container params = task.Parameters;
            DMFExecutionId executionId = conPeek(params,3);
            DMFIntegrationBridge::updateStatus_New(executionId);
        }
    }
}

Customize DMFIntegrationBridge:

public static void updateStatus_New(dmfExecutionId executionId)
{
    IntegrationActivityMessageTable messageStatusTable;
    IntegrationActivityRuntimeExecutionTable runtimeExecutionTable;
    select firstonly messageStatusTable
    join 
    runtimeExecutionTable where runtimeExecutionTable.ExecutionId == executionId && 
    runtimeExecutionTable.MessageIdentifier == messageStatusTable.MessageId;

    DMFIntegrationBridge bridge = new DMFIntegrationBridge();
    ActivityMessageContext ActivityMessageContext = new ActivityMessageContext();
    ActivityMessageContext.MessageId = guid2Str(messageStatusTable.MessageId);
    ActivityMessageContext.ExecutionCorrelationId = str2Guid(messageStatusTable.ExternalCorrelationId);
    // Get status for bridge result
    IntegrationBridgeResults bridgeResult = DMFIntegrationBridgeHelper::GetStateOfExecution(executionId, false);
    // Set post processing state
    bridge.postProcessMessage(ActivityMessageContext, executionId, bridgeResult);
}
