+# Language change for file.deaccessionDialog.reason.selectItem.notValid
+
+"Not a valid dataset." is being changed to "Not valid. This dataset does not comply with repository policies."
+This is the default English language version. For installations using customized languages, replacing the Bundle.properties file, please follow these manual instructions to make this modification, if desired.
+
+Make the change to the Bundle_##.properties file with the new verbiage. Either locally or as an update to [dataverse-language-packs Repo](https://github.com/GlobalDataverseCommunityConsortium/dataverse-language-packs/tree/develop)
+
+The SQL statements to modify the datasets is:
+
+- `UPDATE dvobject SET indextime=null WHERE id in (SELECT dataset_id FROM datasetversion WHERE deaccessionnote='Not a valid dataset.');`
+
+- `UPDATE datasetversion SET deaccessionnote='Not valid. This dataset does not comply with repository policies.' WHERE deaccessionnote='Not a valid dataset.';`
+
+Once the database is updated the Solr indexes need to be rebuilt using the following Admin API:
