If a task has missing metadata, you need to first stop the task.

Navigate to the 'Advanced Run' options.

Select the option 'Metadata Only.'

Start the task with this setting to process the missing metadata.

Stop the task again after the metadata is added.

Resume normal task processing. This procedure ensures that only the metadata is processed without affecting the existing data on the target side. This method is recommended in Qlik Replicate documentation for handling missing metadata issues.

To add missing metadata in a Qlik Replicate task after the task has been stopped, the correct approach is to use the Advanced Run option for metadata only. Here's the process:

Select the task that requires metadata to be added.

Go to the Advanced Run options for the task.

Choose the Metadata Only option, which has two sub-options:

Recreate all tables and then stop: This will rebuild metadata for all available tables in the task.

Create missing tables and then stop: This will rebuild metadata only for the missing tables or the tables that were newly added to the task1.

By selecting the Metadata Only option and choosing to create missing tables, you can ensure that the metadata for the newly added tables is updated without affecting the existing tables and data. After this operation, you can stop the task again and then resume processing.

The other options provided are not the recommended methods for adding missing metadata:

A and D suggest dropping tables or data, which is not necessary for simply adding metadata.

B suggests reloading the target, which is not the same as updating metadata only.

Therefore, the verified answer is C, as it accurately describes the process of adding missing metadata to a Qlik Replicate task using the Advanced Run options1.
