Scheduled Task: Custom Table record only updates after Rebuilding the solution

Irene Gunning asked on November 14, 2022 12:17


I'm still learning to implement custom Scheduled Tasks. I created a class to add and update a record in a custom table and added it as a scheduled task but the table only updates after I Rebuild the solution. The event log shows that the table was updated but the field value never change. It gets the value of the field data from the last Rebuild.

I followed this:

Here is my scheduled task code:

    public string Execute(TaskInfo ti)
        //custom class to add and update a record
        var depotData = new DepotData();

       depotData.AddDepot("3126", "Logistix", "245 Road Cleveland", "Johannesburg", "South Africa", "1449");

        string details = "Custom scheduled task executed. Task data: " + ti.TaskData;

        // Logs the execution of the task in the event log
        Service.Resolve<IEventLogService>().LogInformation("CustomTask", "Execute", details);

        // Returns a null value to indicate that the task executed successfully
        // Return an error message string with details in cases where the execution fails
        return null;

What could be wrong with the code?

What is the code of the DepotData method? What API are you using to update the custom table? When you rebuild the solution = app restart. The app loads the fresh data from the DB after restart. So, the issue is in the code you are using for updating and not in the scheduled task itself. I just tested it with this code and it is working fine.

This is the code for the DepotData class:

using CMS.CustomTables;
using CMS.DataEngine;
using CMS.Helpers;

namespace Custom
    public class DepotData
        string customTableClassName = "MySite.CT_Depot";

        public void AddDepot(string depotCode, string depotName, string addressLine, string city, string country, string postcode)
            DataClassInfo customTable = DataClassInfoProvider.GetDataClassInfo(customTableClassName);

            if (customTable != null)
                // Creates a new custom table item
                CustomTableItem newCustomTableItem = CustomTableItem.New(customTableClassName);

                var customTableData = CustomTableItemProvider.GetItems(customTableClassName).WhereEquals("DepotCode", depotCode);

                if (customTableData.Count == 0)
                    // Sets the values for the fields of the custom table
                    newCustomTableItem.SetValue("DepotCode", depotCode);
                    newCustomTableItem.SetValue("DepotName", depotName);
                    newCustomTableItem.SetValue("AddressLine", addressLine);
                    newCustomTableItem.SetValue("City", city);
                    newCustomTableItem.SetValue("Country", country);
                    newCustomTableItem.SetValue("DepotPostcode", postcode);

                    // Save the new custom table record into the database

                    foreach (CustomTableItem item in customTableData)
                        item.SetValue("DepotName", depotName);
                        item.SetValue("AddressLine", addressLine);
                        item.SetValue("City", city);
                        item.SetValue("Country", country);
                        item.SetValue("DepotPostcode", postcode);

                        // Saves the changes to the database


I'm testing it for now. The plan is to update the objects if there are changes every 5 mins and the data will be fetched from the SAP server. The data would be in CSV format.

Have you considered using Integration bus? Also keep in mind the performance point of view - I do not know how many items are in the custom table, but it could become a nightmare. I would recommend to discuss this goal with somebody experienced or even schedule an ad-hoc session with our solution architect to implement this right and avoid headache in the future.

Have you checked that the scheduled task is enabled? How about the scheduled execution of the task? What are the parameters for how often the task is to be executed?

There could be an error in your sub-method AddDepot() that causes the task to fail and get stuck so it doesn't execute again.

The task gets executed successfully and there was no error in the logs.

When I delete the record, it gets added again but the data added is from the previous Rebuild.
