When a data file needs to be locked to prevent any further changes such as for an Actual file or Working Forecast files this can be easily updated in the Data File Manager:
- From IFP Home select Databases / Files > Data File Manager
- Select the relevant forecast file, e.g. 2017 Actual
- From the toolbar select Properties
- Select Status
- Lock the file to the required month or fully locked to stop any further changes being made to this file
Note: These settings can only be changed by Local or Regional Administrators.
