A new permission, 'Admin Module: Immunizations_Use Lot Management Scan Only,' has been created. This permission will be unchecked by default. 

When the permission 'Admin Module: Immunizations_Use Lot Management Scan Only' is enabled, the fields on the Lot Management tab are non-editable.

When the user scans the vaccine lot information, the system automatically populates the Lot Number and NDC fields with the scanned data. If the scanned values in these fields contain at least four characters, the system will enable all lot management fields for manual edits.

If users manually reduce the Lot Number or NDC Number to less than four characters in entry or edit mode, all fields will be cleared and remain non-editable.
