Description of problem:

The Incremental Update for Red Hat errata fails when hosts are subscribed to both:

Composite CV for RHEL content

Rolling CV

During the Incremental Update, Satellite incorrectly tries to create/update a version for the Rolling Content View, although rolling CVs do not support versioning and are unrelated to the selected Red Hat errata.

The operation fails with:

undefined method `version_href' for nil:NilClass
The failure appears in pulp3_repo_mapping, where a repository version object is expected but nil is returned for the rolling content view.

How reproducible:
100%

Is this issue a regression from an earlier version:

NA

Steps to Reproduce:

Steps to Reproduce:

Create two CV:

• Composite CV with Red Hat repositories
• Rolling CV (Custom repositories)
• Register a host subscribed to both CVs.
• Go to Content → Errata.
• Select a Red Hat erratum (example: RHBA-xxxx:xxxx).
• Choose Apply via Incremental Update.
• Start the operation.

Actual behavior:

Satellite attempts to process the Rolling Content View during Incremental Update and fails with:

Expected behavior:

Satellite should only process the relevant Composite/Versioned Content View containing the affected Red Hat repositories and ignore Rolling Content Views during Incremental Update operations.

Business Impact / Additional info:

Customers using both Composite and Rolling Content Views cannot apply errata using Incremental Updates, blocking standard patch management workflows.
