    2. Error Response— See Exhibit 2.3.26-3.

    ERROR MESSAGES CONDITION
    1. TIN INVALID TIN entered was invalid due to improper format, i.e. alpha character or hyphens in the wrong place.
    2. TIN & FILE-SOURCE-CD NOT CONSISTENT File Source Code is invalid or File Source Code is not consistent with the TIN.
    3. NO FILE AVAILABLE The TIF file requested was not available for Real Time research.
    4. DATA UNAVAILABLE The TIF area is still being updated by the weekend programs.
    5. ACCESS RESTRICTED The TIF area is not available at the moment; please try another area or try this area later.
    6. AREA IS DOWN The TIF area is not available at the moment; please try another area or try this area later.
    Note: TDINQ will perform a security check of the user profile to determine if the user is restricted for access to IMF-only or BMF-only accounts. If the user profile and the input request are not consistent, one of the following error messages will be generated:
    7. PROFILE IMF ONLY The user is profiled for access to IMF accounts only. The input account is not IMF.
    8. PROFILE BMF ONLY The user is profiled for access to BMF accounts only. The input account is not BMF.
