While running Qlik NPrinting Tasks, many reports are generated. However, the setting for Days to Keep / Reports to Keep seems to be ignored.
Qlik NPrinting all versions
The first thing to consider is that Qlik NPrinting generates one report for each Newsstand user. For this reason, there will be one file for each user, and not "just one", in the Qlik NPrinting Application Data folder. Those reports may be absolutely identical.
In that sense, the "report to keep" setting does not apply here, and should be considered as "report to keep per user". There is currently an improvement at R&D. Check improvement on days to keep in Nprinting for details. In addition, see Publish task "Reports to Keep" does not work during first 24 hours.
As for the setting apparently being ignored, by default runs the check to delete old reports once every 24 hours. If no new report has been run in the meantime, the old reports will not be deleted, even if more than one day has passed.
Should there be a feeling that the periodic check is not run, the settings can be enforced:
<add key="cleanup-period" value="1800" />
<add key="cleanup-period-files" value="43200" />
The first setting is the recurrence in seconds (default: 30 minutes) for the task that will check for reports in the newsstand and unlink the older ones.
The second setting is the recurrence in seconds (default: 24 hours) for the task that will scan and remove the actual files, after checking that the conditions about days and reports to keep, plus the presence of newer reports that supersede them, are met. In this case, we would change the default value to a shorter time (43200 seconds, 12 hours) to make sure the task is run more frequently.
A Qlik application has been successfully reloaded in a tenant. The reload has stored additional tables in a QVD.
Reviewing the Dataset (QVD) in the Catalog does not show the correct number of rows after the reload. The information is not automatically updated.
The rows only update once the Compute button is clicked.
This is currently working as expected.
Qlik plans to provide scheduling capabilities for the Profile and Data Quality compute. No estimated release date or other details can yet be determined for this feature.
Profiling information is not automatically refreshed when QVD files change.

This guide briefly offers a step-by-step process on how to set up key-pair authentication in Snowflake using Qlik Talend Studio at Job level
The process can be summarized in three steps:
The .p12 file contains both the private and public keys, along with the owner's details (such as name, email address, etc.), all certified by a trusted third party. With this certificate, a user can authenticate and identify themselves to any organization that recognizes the third-party certification.
Talend tSetKeyStorecomponent itself can only take in .jks or .p12/.pfx format. If you are using PKCS8 format, you need to convert your p8 certs into a supported format.
Generate the key with the following command line prompt:
openssl genpkey -algorithm RSA -out private.key -aes256This will generate a private key (private.key) using the RSA algorithm with AES-256 encryption. You'll be prompted to enter a passphrase to protect the private key.
openssl req -new -x509 -key private.key -out certificate.crt -days 1825This command generates a self-signed certificate (certificate.crt) that is valid for 5 years. You will be prompted to enter details like country, state, and organization when generating the certificate.
openssl pkcs12 -export -out keystore.p12 -inkey private.key -in certificate.crt -name "abe"And check the created .p12 file information with below command:
openssl pkcs12 -info -in keystore.p12 or keytool -v -list -keystore keystore.p12
openssl x509 -pubkey -noout -in certificate.crt > public.key

Erlang/Open Telecom Platform (OTP) has disclosed a critical security vulnerability: CVE-2025-32433.
Is Qlik NPrinting affected by CVE-2025-32433?
Qlik NPrinting installs Erlang OTP as part of the RabbitMQ installation, which is essential to the correct functioning of the Qlik NPrinting services.
RabbitMQ does not use SSH, meaning the workaround documented in Unauthenticated Remote Code Execution in Erlang/OTP SSH is already applied. Consequently, Qlik NPrinting remains unaffected by CVE-2025-32433.
All future Qlik NPrinting versions from the 20th of May 2025 and onwards will include patched versions of OTP and fully address this vulnerability.

An endpoint security system may have flagged the Qlik NPrinting Designer process as it accesses the svchost.exe file in C:\Windows\SysWOW64\.
Qlik NPrinting Designer may try to read svchost.exe during the Office embedding process, but it never opens or edits the file. This excludes any possible security risks.
Qlik NPrinting Designer was tested without access to svchost.exe and functions as expected even when access has been blocked.
After deploying and subsequently undeploying a route, even when the route is undeployed, it causes issues for the deployment of subsequent routes. Attempts to deploy a different route are met with errors stating that unable to find the path of the existing undeployed route.
The undeployed route left traces, ideally requiring the individual uninstallation of the KAR file(s).

Hello and welcome to this short video guide on upgrading a Qlik Sense token server to a Qlik Sense Professional and Analyzer subscription license.
Our starting point for this upgrade guide is a very simple Qlik Sense Enterprise server, which is using the token style license. That means users gain access using either a User Access or a Login Access pass. Token style Qlik Sense uses the legacy LEF license with a serial and control number activation. This will be replaced in the Professional and Analyzer model license with a Signed License Key (SLK).
Make sure that you copy or save the existing user access rules storing the rules for future reference. We will do the same for the login access rules. Copy and save the rule conditions for future reference.
When you're issued with your new Qlik Sense Enterprise Professional and Analyzer subscription license, you will be issued a new license key or a new tenant. You may continue to use the old Qlik Sense Enterprise token license for up to four months. This will allow you to stand up a new Qlik Sense Enterprise site with Professional Analyzer users in parallel, and transition over time; or do it in one big go.
In this example, we are going to upgrade an existing Qlik Sense token server using the Signed License Key to move it to the Professional and Analyzer user model. Paste the Signed License Key in the signed license box and hit apply. When the license is successfully applied, you will see the license number as well as a license summary on the summary page. In this example, we have 4 Professional Users, as well as 8,000 minutes of Analyzer Capacity per month. There are no user allocations carried over from the old token model.
We need to recreate the Professional access rules. You can create rules from scratch or copy and paste the old token rules to a new Professional allocation rule, like so. Make sure you validate the rule and then hit apply.
We will do the same thing for the Analyze Capacity access rule. Copy the old token access rule for login access and paste it in the analyze capacity access rule. Validate the rule and hit apply. A quick test will validate that the Professional user access rules are functioning correctly. And here we can see that a Professional user was successfully allocated according to the rule we've set up.
Now we will check that the Analyzer capacity allocation rule is also working as expected. Click on the license usage summary tab; and here you can see that 6 minutes of analyzing capacity have been consumed. Everything is working as expected.
Thank you for watching. We hope you found this video useful.

The following error is thrown when running an ETL task on a specific table in Qlik Compose:
ETL task aborted - Unexpected Primary Key violations detected in 'Table Name'.
Enable Handle Duplicates on the problematic table.
Troubleshooting steps taken:
If the lookup tables contain duplicate records, the query will insert those duplicates into the staging table, leading to the PK violation errors.
When opening the Table Selection option in the Designer tab or clicking the Test Connection button for an endpoint, the following error may appear:
Error: SYS-E-HTTPFAIL, SYS-E-UNRECREQPARM, Unrecognized request parameter 'action'.. SYS,GENERAL_EXCEPTION,SYS-E-UNRECREQPARM, Unrecognized request parameter 'action'.,SYS,UNRECOGNIZED_REQUEST_PARAMETER,action
Restart the Qlik Enterprise Manager service.
Qlik Enterprise Manager API calls are not processing parameters correctly.
When the Use direct path full load option is in use for an Oracle as a target endpoint, some integrity constraints are automatically disabled and will be recreated after the Full Load, such as Indexes.
Failure to create the Indexes will result in the following error message in your task log once CDC replication starts and the task attempts to use the index:
[TARGET_APPLY ]E: ORA-01502: index 'Schema.Table' or partition of such index is in unusable state [1020436] (oracle_endpoint_bulk.c:893)
Identify the root cause of the Index creation failure with your Oracle DBA. This particular scenario failed to create the Index as the Oracle DB did not have enough temp table space to create the Index on the large tables.
The issue was resolved by increasing the temp table space used for the Index creation to unlimited.
The Oracle target Database did not have enough temp table space to complete the Index creation for the table.

To achieve the default behavior where a delete gets a 'D' value for header_change_operation, remove the Operation_indicator function from your transformation.
See the headers and functions documentation for details:
Replicating data from Oracle, where the data type is `RAW` (such as C6B578B216B05B2555541FBD6BF1B216B046B00B25), casting the `RAW` data to a `STRING` results in the value being stored with a `0x` prefix (such as: 0xC6B578B216B05B2555541FBD6BF1B216B046B00B25).
Transformations to remove the `0x` prefix specifically will not work. The Hex function should be applied to the column to remove the `0x` prefix.
The '0x' prefix is added by the AWS S3 reader. To resolve this, modify the transformation process in Qlik Replicate by applying the hex function when converting to a string. On the column's expression builder, add hex($Column_Name) where Column_Name is the name of your Raw datatype column.
AWS S3 reader converts the Raw datatypes with additional prefixes due to how the Binary data is processed.

In Qlik Sense, bookmarks can be created with the "Include Layout State" option to capture both current selections and the layout of visual objects, such as the expanded or collapsed state of pivot tables. However, users may notice that after reloading the document and reapplying the bookmark, the pivot table does not return to the expected expanded/collapsed layout.
To ensure that the pivot table layout is retained when using bookmarks:
This behavior is due to how Qlik Sense manages the expand/collapse structure in pivot tables. Specifically:
Impact of Changing Dimensions in a Pivot Table
