The Refresh Synonyms option helps to refresh metadata tables to reflect the later changes in the metadata.
Navigate to the Data Store Metadata list.
Select a Metadata Store from the list.
Click the Refresh Synonyms icon.
A confirmation message appears to inform the users that the Synonyms are updated.
Please Note: While using the Refresh Synonyms option, all the previously added Synonyms get cleared. The user needs to use the Add Synonyms option to insert synonyms in the same Metadata Store.
