Signals Notebook: Container is not shown in samples table row where we have a linked Material ID

The system is designed in such a way that if a user chooses to make a container from the Samples table where a Material ID is linked, the container will be created under the Material (with batch if applicable) and will not appear in the Samples table since the container is associated with the Material and not the Sample.

You can find this documented in the Help Center - Signals Notebook > Working with Information Items > Working with Samples > Creating Containers from the Samples Table
