KnowledgeArticleVersion

Use this object to:

Query or search generically across multiple article types.
Filter on a specific version.
Update standard fields, those fields that are updateable, in draft versions.

When you query on the archived article, the results include both the article and the article’s archived versions.

You can’t update draft translations with the API.

Note

Supported Calls

create(), delete(), describeLayout(), describeSObjects(), query(), retrieve(), search(), and update().

You can only update draft versions.
To create, update, or delete a Knowledge article version, use the call on ArticleType_kav, where ArticleType is the name of the article’s type. For example, to delete, use ArticleType_kav.delete().

Note

Special Access Rules

A user must have the “View Articles” permission enabled. Salesforce Knowledge users, unlike Customer Portal and partner portal users, must also be granted the Knowledge User feature license to view and edit article versions.

Usage

Use this object to query, retrieve, or search for articles across all article types depending on their version. You can update draft master articles. Additionally, you can delete articles that are not drafts. Client applications can use KnowledgeArticleVersion with describeDataCategoryGroups() and describeDataCategoryGroupStructures() to return the category groups and the category structure associated with Salesforce Knowledge.

Alternatively, client applications can use the article type API Name followed by __kav to query, retrieve, or search for articles for a specific article type.

To access an article independent of its version, use the KnowledgeArticle object.

SOQL Samples

The following SOQL clause uses the article type API Name to limit the query to all draft articles from the Offer__kav article type:

The following SOQL clause uses KnowledgeArticleVersion to query the Ids of all archived versions of a particular article:

SOQL and SOSL with KnowledgeArticleVersion

Always filter on a single value of PublishStatus unless the query filters on one or more primary key IDs. To support security, only users with the “Manage Articles” permission see articles whose PublishStatus value is Draft.
Archived article versions are stored in the articletype_kav object. To query archived article versions, specify the article Id and set IsLatestVersion='0'.
Always filter on a single value of Language. However, in SOQL, you can filter on more than one Language if there is a filter on Id or KnowledgeArticleId.
You cannot use binding variables in Apex SOQL statements with KnowledgeArticleVersion objects. For example, the following SOQL statement causes a compilation error.

Instead, use dynamic SOQL as follows. See Dynamic SOQL in Apex Developer Guide.

Additional Usage for SOQL and SOSL with KnowledgeArticleVersion

To expose the migrated_to_from_id on KnowledgeArticle and KnowledgeArticleVersion to the sObject API: expose MigratedToFromArticleVersion in KnowledgeArticleVersion.

For SOQL:
- To filter by MigratedToFromArticleVersion, remove any other filters.
- When filtering by MigratedToFromArticleVersion, use the '=' or 'IN' operator.
- When filtering by MigratedToFromArticleVersion, the value can't be null or empty.
SOSL doesn’t support MigratedToFromArticleVersion.
