    G001Invalid Segment Order

    Segments are not in the required sequence

    Description

    Metro 2 requires segments to appear in a specific order: Header, then for each account (Base, J1, J2, K1, K2, K3, K4, L1, N1), then Trailer. Optional segments must follow their defined sequence. Out-of-order segments will be rejected.

    Common Causes

    • File sorting disrupted segment order
    • Segments added without maintaining order
    • Source data groups not in correct sequence

    How to Fix

    1. 1Maintain proper segment order during generation
    2. 2Don't sort the file after generation
    3. 3Group all segments for each account together

    Metro 2 code reference

    A rejected value is usually a wrong code rather than a wrong format. Every CRRG code set has a per-code page with its meaning and cross-field rules. Metro 2 codes: the complete cheat sheet puts all of them on one page.
