Hi Scott,

As Steve mentioned, the Data Integrity Check in Ledger would not detect any errors in the data files specific to the Financial Reporter (Department ranges and lists, Statement Groups, etc). The file could be bad but the Ledger DIC would be clean.

You didn't mention the version of the Financial Reporter in use. Please indicate this from the Help / About screen in the Financial Reporter. Such as 2.1.8.2761. Please also indicate whether the program file name has 64 or not, so we know whether this is the 64-bit or 32-bit version of the program. Some changes to the department field object were made in the most recent release of Ledger 9.3B (2021.05.27).

The name of the data file that maintains the department ranges, masks, lists and display sequence is GLDTREE.dat. It can be opened by a text editor including Notepad to take a peek, though I do not recommend making any edits to it. This file is only ever used by the Financial Reporter, though it also is updated when editing Departments in Ledger.

If the ability to save or not save a new List is not consistently repeatable following the exact same steps, it would seem to have to do what the ability to access and write changes to the GLDTREE data file at that moment in time.
