Good day, colleagues.

 

IProcessExecutor processExecutor = _userConnection.ProcessEngine.ProcessExecutor;
return processExecutor.Execute("VERY_IMPORTANT_PROCESS", valuesDictionary);

 

In context of my question, this simple script have multiple calling from different users (sessions) in one period of time. So i need to use Supervisor UserConnection to clarify "VERY_IMPORTANT_PROCESS" logging. Is it possible? Any workarounds?

Hello,

 

Something similar was implemented in the RunSendEmailToCaseGroupV2 business process:

UserConnection userConnection = UserConnection;
if (userConnection.CurrentUser.ConnectionType == UserType.SSP) {
	userConnection = userConnection.AppConnection.SystemUserConnection;
}
...

Here the system checks if the current user is an external user and if so - replaces the userConnection with systemUserConnection (which is a Supervisor user).

 

You can try the same approach in your code to make sure the business process is called under the Supervisor user.

I try to run the script task in a business process to create a printable. If the business process is started by user, it'll work just fine, but when the process is started by another process or an event it'll break with an exception:

System.NullReferenceException: Object reference not set to an instance of an object.

   at Terrasoft.Configuration.ReportService.ReportService.GetSchemaNameByTemplateId(Guid templateId)

   at Terrasoft.Configuration.ReportService.ReportService.GenerateMSWordReport(String urlTemplateId, String urlRecordUId, Boolean convertInPDF)

   at Terrasoft.Core.Process.ProcessInvoiceAutoSendCustom1Custom21Custom2MethodsWrapper.ScriptTask2Execute(ProcessExecutingContext context)

   at Terrasoft.Core.Process.ProcessFlowElement.Execute(ProcessExecutingContext context)

The script task is like this:

var PrintableId = Get<string>("PrintableId2");
var ObjectIdInvoice = Get<string>("ObjectIdInvoice1");
var ConvertToPdf = Get<bool>("ConvertToPdf");
var AddInvoiceId = Get<Guid>("AddInvoiceId");
var AttachmentType = Get<Guid>("AttachmentType");
 
var userConnection = Get<UserConnection>("UserConnection");
 
var reportService = new Terrasoft.Configuration.ReportService.ReportService();
Terrasoft.Configuration.ReportService.ReportData report = reportService.GenerateMSWordReport(
    PrintableId, ObjectIdInvoice, ConvertToPdf);
var entity = userConnection.EntitySchemaManager.GetInstanceByName("InvoiceFile");
var fileEntity = entity.CreateEntity(UserConnection);
fileEntity.SetDefColumnValues();
fileEntity.SetColumnValue("InvoiceId", AddInvoiceId);
fileEntity.SetColumnValue("TypeId", AttachmentType);
fileEntity.SetColumnValue("Name", "Invoice.pdf");
fileEntity.SetColumnValue("Data", report.Data);
fileEntity.Save();
return true;

I guess ReportService doesn't obtain UserConnection from Supervisor user, so it can't get instance of "InvoiceFile". Is that the case?

How to change the script to make ReportService work with Supervisor or maybe with UserConnection of another user?

In a script task in an interpretive business process you need to get "user connection"  with the following syntax:

var userConnection = Get<UserConnection>("UserConnection");

Additionally, please note that if you want to work with process parameters in a script task, you need to write in the following manner:

var parameter1 = Get<Guid>("Parameter1");

Set("Parameter2", parameter1.ToString());

var parameter2 = Get<string>("Parameter2");



Also, from exception message it seems that desired template not exists in the system, so you should check it.

I have a similar requirement to send report automatically to users at a certain frequency. We use Creatio 7.18.5 and the report was built using the old ReportDesigner for 7.14 and was carried over to the new version when we upgraded. 

I tried to follow this article to create the report as part of our process - https://community.creatio.com/articles/generate-printable-and-send-it-attachment-email

When the process is manually run by the user, the report gets generated. But when scheduled to run by Supervisor using timer, it gives below error - 

Terrasoft.Core.InstanceActivationException: Error creating an instance of the "Terrasoft.Tools.DevExpressReport.IReportProvider" class ---&gt; Ninject.ActivationException: Error activating UserConnection using binding from UserConnection to method
Provider returned null.
Activation path:
  3) Injection of dependency UserConnection into parameter userConnection of constructor of type DevExpressConfReportLocalizationReader
  2) Injection of dependency IDevExpressReportLocalizationReader into parameter reportLocalizationReader of constructor of type ConfigurationDevExpressReportProvider
  1) Request for IReportProvider
 
Suggestions:
  1) Ensure that the provider handles creation requests properly.

Below is the report generation part of the code -  

//ReportService reportService = new ReportService(userConnection);
//ReportData report = reportService.GenerateDevExpressReport(entitySchemaUId,reportSchemaUId,null,reportParamaters);
 
DevExpressReportGenerator reportGenerator = new DevExpressReportGenerator();
var configuration = new ReportGeneratorConfiguration {
				ReportTemplateId = !string.IsNullOrEmpty(reportSchemaUId) ? new Guid(reportSchemaUId) : Guid.Empty,
				EntitySchemaUId = !string.IsNullOrEmpty(entitySchemaUId) ? new Guid(entitySchemaUId) : Guid.Empty,
				RecordId = !string.IsNullOrEmpty(recordId) ? new Guid(recordId) : Guid.Empty,
				ReportParameters = !string.IsNullOrEmpty(reportParameters)
					? JsonConvert.DeserializeObject&lt;Dictionary&lt;string, object&gt;&gt;(reportParameters)
					: null
			};
ReportData report = reportGenerator.Generate(userConnection, configuration);

I understand it's an old version of the report but I would appreciate if anyone can provide any insights on what I'm missing.

Hello Nirupama, Can you check if the run elements in the background is disabled ? If that is enabled, then the process will not get the User Connection.
