  • An exception to this is that the repository has options to allow agencies to follow older specs.  e.g. in some states, the Repository still accepts shorter segment lengths that are missing Cargo Theft, LEOKA fields, extra biases, and offender ethnicity.  (ME and NH have been tested on the build server and they allow submission of the shorter segment lengths)
  • The repository also continues to accept deprecated codes, such as location 22 and offenses like 90A and 90I, until a state asks us not to (MO, NH). (On a build server NH accepted 90A and 90I, ME accepted 90A but not 90I)
  • If a new error code is similar to an old one and gives the same meaning, Repository might still report the old code, e.g. throwing error 601 when the FBI spec says to throw error 604
  • In some states (ME, NH, MS and SC), the software still supports single-segment updates (such as adding an arrestee or recovered property to an existing incident).  This has been removed from the FBI specification, and the full incident is submitted to the FBI when these updates are applied.
  • Offenses created for reporting federal and tribal LEAs are not supported.

  • The FBI changes from the 2025.0 spec that we did not implement include:

    • Error 106, requiring a time for incidents involving LEOKA, has not been removed.
    • Error 258, allowing the "automatic" qualifier only for firearms, has not be changed to a warning
    • Error 265, allowing only certain weapons with a Simple Assault, has not been changed to a warning
    • Error 383, requiring a blank property value for seized drugs, has not been changed to a warning
    • Error 475, allowing only one spouse per victim, has not been changed to a warning
  • As part of the 2023 Specification, the FBI indicated that they had removed error 560, which forces at least one offender to be of a different sex from the victim of rape (offense 11A). The reality is that the FBI still generates error 560 for incidents that occurred before 01-Jan-2021. We changed our code to reject all incidents with an incident date before 01-Jan-2021 if a victim of offense 11A is the same sex as all offenders in the incident.
