    Hello Qlik Community,

    We would like discuss about a suspected issue in Qlik Replicate. After a source table is recreated and explicitly reloaded, Full Load completes successfully, but subsequent changes to that table are not captured. CDC resumes only after an additional Stop → Resume.

    Environment

    • Qlik Replicate: 2026.5.0.423.  Sourse and Target use same  Microsoft SQL Server 2019, Microsoft SQL Server (MS-CDC) 

    • Task  Full Load + Apply Changes + Store Changes enabled. DDL action all ignored 

      The test uses two tables:

      • dbo.VersionTest — the table being recreated.

      • dbo.CdcHeartbeat — an unaffected control table. A stored procedure continuously generates committed updates to this table so that the task’s LSN position continues to advance.

      •  

      The heartbeat procedure remains running throughout the experiment, including periods when the Replicate task is stopped.

      VersionTest has a primary key and simple text/numeric columns, without LOB or rowversion columns. We reproduced this behavior in a laboratory while investigating replication recovery after BAS application table restructuring.

      Steps to reproduce

      1. Start the Replicate task and confirm that CDC works for both tables. Start the procedure generating continuous committed updates to CdcHeartbeat.

      2. While the Replicate task is running, drop dbo.VersionTest.

      3. Create a new table named dbo.VersionTestNG.

      4. Rename dbo.VersionTestNG to dbo.VersionTest. The table now has the original name but a different SQL Server object_id.

      5. Manually enable MS-CDC for the new dbo.VersionTest. Verify that changes to this table appear in the source cdc.dbo_VersionTest_CT.

      6. Stop the Replicate task and wait until it is Stopped. Mark VersionTest for Reload while the task is stopped, then select Resume Processing.

      7. Wait for Full Load to complete successfully. Execute and commit an UPDATE setting the test value to PROBE_A. This event appears in the source CDC table but does not appear in the target VersionTest__ct. Meanwhile, heartbeat changes continue reaching the target and advance the saved task position beyond the LSN of PROBE_A.

      8. Perform another Stop → Resume Processing, without an additional Reload.

      9. Execute and commit another UPDATE setting the value to PROBE_B. This change is captured successfully. The target VersionTest__ct contains the transition PROBE_A → PROBE_B, but the previously missed event that changed the value to PROBE_A is not recovered.

      Expected behavior

      After an explicit Reload refreshes the recreated table’s metadata, CDC should resume for that table.

      If this DDL scenario requires additional recovery steps, we need a documented, supported procedure that prevents missed changes and clearly identifies when capture remains inactive.

      Observed mechanism

      At the first Resume, the capture component detects the missing old object and removes its registration. Reload subsequently refreshes the metadata for the new object, but the new CT is not added to the running capture component’s polling list.

      The additional task restart establishes the correct registration and restores polling.

      The task continues processing other tables and advancing its LSN while capture of VersionTest remains inactive. This creates a gap in the change history, which is critical for downstream historical processing.

      An additional Stop → Resume restores future CDC processing but does not recover the missed interval. The current workaround therefore requires keeping writes to the recreated tables paused until Reload, the additional restart, and CDC verification have completed.


      what is best
      supported recovery procedure after replacing a source table with a new object under the same name?

    Hi everybody!

     

    I'm struggling with the trellis container extension from the dashboard bundle. 

    I've got a dimension populated with months (jan to dec) and I've selected 3 of them.

    No matter what I try, the trellis container keeps showing me 12 charts, 3 of then with values and the rest of them with a message like this "Actual selections hasn't got any data for this chart" (sorry, my Qlik Sense is configured in spanish so thats' just a translation)

     

    What I expected to have is a three charts container, not a 12 charts container with eleven empty charts.

    Am I doing something wrong?

     

    I'm using the lastest Qlik Sense version (february 2020)

    Thanks in advance

    Years ago I wrote the QlikView Systems Monitor (ugly but one of the most downloaded apps of its era). This is the same itch, scratched with 2026 tools.

    Qlik Cloud has a native MCP endpoint for AI agents. Client-managed Qlik Sense on Windows has no official equivalent, so at Terenzi LLC we built one and open-sourced it under Apache-2.0. qseow-mcp exposes the QRS, Engine, and Proxy APIs as 44 agent tools across analyst, troubleshooting, developer, and admin personas. There is other community work in this space, and more of it is a good thing; our focus is the support and troubleshooting surface, full JWT-mode coverage, and a hard security posture.

    The part we care most about is the troubleshooting loop. When a number is wrong, an agent can walk KPI to object to sheet to app to script to source, evaluating the governed definition at every step. In our demo estate it traces a $50M reconciliation mismatch to a double-loaded batch and ties it back out in seconds of tool time.

    Two practical notes for anyone who tries it:

    1. Published-app caveat: the engine hides a published app's script and lineage from user identities (GetScript returns empty, GetLineage denies, even for RootAdmin under a user identity). The workaround is copy_app and trace the owned copy. This is documented platform behavior, not a bug in the server, and it will bite any agent integration you build yourself.

    2. The engine validates expressions but never proves pixels. A hypercube the engine accepts can still render a blank chart client-side (nebula.js default property blocks). The server ships a validate_sheet gate and all 12 supported chart types are render-verified against a real browser.

    Repo: https://github.com/rmterenzi/qseow-mcp · Install: npm i qseow-mcp

    Read-only by default, mutating tools gated at registration, credential redaction on every output path, certificate and JWT auth both covered. Independent project by Terenzi LLC (we are a Qlik partner; this is not a Qlik product). Issues and PRs welcome, especially reports from multi-node sites — everything so far is validated on single-node May 2026.

    SQL MERGE and updates on primary keys

    Hello,I’ve configured a replication task that reads from a Log Stream and replicates data to a Snowflake target with Apply Changes Processing enabled,... Show More

    Hello,

    I’ve configured a replication task that reads from a Log Stream and replicates data to a Snowflake target with Apply Changes Processing enabled, meaning that changes are applied directly to the target tables in Snowflake. The source of the Log Stream is an Oracle database.

    Moreover, I’ve implemented a soft-delete logic in this task by adding a technical field defined as follows:

    CASE ifnull(operation_indicator('DELETE','UPDATE','INSERT'),'null')
    WHEN 'null' THEN 'INSERT'
    ELSE operation_indicator('DELETE','UPDATE','INSERT') END

    Occasionally, operations are performed on the source that modify primary key fields. I’d like to understand if it’s possible to transform the UPDATE into a DELETE of the record with the previous key, followed by an INSERT of the record with the new key.

    As I understand it, the “DELETE and INSERT when updating a primary key column” option available in Apply Changes Processing cannot be used to achieve this because for the Snowflake target endpoint this option applies only to Change Tables, not to the actual target tables.

    However, I noticed that there is also an “Apply changes using SQL MERGE” option. If I understand correctly, this option works as follows: “for a standard UPDATE, Qlik Replicate generates a MERGE INTO statement. However, if the UPDATE modifies primary key values, Qlik Replicate will not use MERGE INTO; instead, it will apply the change as a DELETE + INSERT pair for that row”.

    This behavior is described in the following article:
    https://community.qlik.com/t5/Official-Support-Articles/Qlik-Replicate-Implementing-UPSERT-and-MERGE-modes-by-applying-a/ta-p/1780009.

    If this is how SQL MERGE operates, would implementing a soft-delete logic mean that, when a primary key changes, the target table would contain the record with the old primary key marked as deleted (soft-deleted) and the record with the new primary key inserted as a new record?

    Thank you in advance for your support.

    Best regards

    Hi, we have several automations under development, each of which were fine last week.  Today, we wanted to change the name of one of them, so attempted to open the automation settings, and it raised the alert "Unauthorized: You do not have access to this automation. Contact your system administrator for more information."
    We have tried opening these settings on other automations, and get exactly the same.  Edits to the automation blocks are working fine, so why are they being shown as unauthorized for the settings?

    Note:  I am the administrator and, as far as I can see, the account attempting to open the automation settings is the owner of the automation, and no roles or permissions have been changed between last week and this.

    Thanks.

    Hi everyone!

    If you develop in Qlik Sense, you know the scene: the load script changed, the number on the dashboard changed with it, and nobody knows who changed it, when or why. To solve this, we built Versiona CuboPlus, a free extension for Chrome and Edge that keeps the history of your load script in your company's Git repository.

    Intro video: 

    How it works

    • You open the app in Qlik, and a mascot tells you when the script has changed and has no version yet.
    • You write what changed and why, and the version becomes a commit in GitLab or GitHub, with you as the author.
    • You can see the line-by-line differences before saving, browse the history and restore a previous version.
    • Optional: the expressions of master measures and dimensions and the app variables go along, in a file next to the script (read-only).

    Where it works

    • Qlik Sense Enterprise on Windows and Qlik Cloud.
    • GitLab, including self-managed, and GitHub.
    • In English, Portuguese and Spanish.

    Security

    • The script goes from your browser straight to Qlik and to the Git you configured: it goes through no other server, and there is no telemetry.
    • The extension does not write to public repositories: the repository must be private.
    • The Git token is encrypted in the browser, and you can require the Windows Hello PIN or biometrics to use it.
    • IT can distribute the configuration by policy (GPO).

    For client-managed, there is also an optional nightly routine in PowerShell for GitLab, open source, that stores overnight whatever changed without going through the extension.

    Download and more

    It is free. If you try it, tell us here what you think, and leave a review on the Chrome Web Store.

    Suggestions and bug reports are very welcome.
