# Permission Checker The CopyStorm/Medic Permission Checker will find Salesforce tables and fields that are visible using the Salesforce metadata API but are not visible for backup using the current Salesforce credentials. It is a common misconception that a member of the Salesforce Administrator group can see all table and fields in a Salesforce instance. In practice, there are even many standard Salesforce fields that a Salesforce Administrator cannot view by default. The Permission Checker helps you find these tables and fields. ## Running the Permission Checker in a GUI Running the Permission Checker involves clicking on a single button – Start Scanning Metadata. * The Salesforce user credentials provided to the Permissions Checker must have access to read the Salesforce metadata definitions for each object. * Use of the metadata API requires the system permission “Modify Metadata Through Metadata API Functions.” ![](https://4057376488-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FsbSqfKw3vSfr8qwXao4j%2Fuploads%2Fgit-blob-a2143dd675376fefc2877da68d988a8e4f1951a4%2F4dc4c827-permissions_checker.jpg?alt=media) Do not be alarmed when you find a lot of fields that are not visible to a Salesforce Administrator. Most likely you are not using them in your instance. ## Running Permission Checker as a Batch Job The Permission Checker tool can be run as a batch job using the following syntax: * Windows * CopyStormMedic.bat -tool findPermissionErrors -run configFile.copyStormMedic * Linux * sh CopyStormMedic.sh -tool findPermissionErrors -run configFile.copyStormMedic --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
