    Regel:        SQLI-AX-005 – Dynamics AX-nummerserie er ved at løbe tør
    Alvorlighed:  Medium; Høj (High) over den kritiske procent eller inden for de kritiske dage; Kritisk (Critical), når serien er opbrugt

    Hvad og hvorfor
      Når en nummerserie er brugt op, kan AX ikke tildele flere numre: oprettelse eller bogføring af fx ordrer, fakturaer
      eller posteringer, der bruger serien, fejler for alle brugere.

    Tærskler (agentens konfiguration SQLInsight:DynamicsAx)
      NumberSequenceWarnPercent = 80       brugt mindst så mange procent: Medium
      NumberSequenceCriticalPercent = 95   …: Høj
      ForecastWarnDays = 90                løber tør inden for så mange dage efter prognosen: Medium
      ForecastCriticalDays = 30            …: Høj
      ForecastBasisDays = 30               prognosen bruger den ældste daglige måling inden for så mange dage (mindst 1 dag gammel)

    Vurdering (C#: src/SQLInsight.Rules/DynamicsAx/DynamicsAxRules.cs – AxNumberSequenceExhaustionRule; tal i
    src/SQLInsight.Core/DynamicsAx/AxSchemaAdapter.cs – Interpret og AxForecast.From)
      Grænse = HIGHEST, eller formatets kapacitet (10^antal # − 1), hvis den er lavere. Brugt % = (NEXTREC − LOWEST) /
      (grænse − LOWEST + 1). Tilbage = grænse − NEXTREC + 1. Prognose: forbrug pr. dag = (NEXTREC nu − NEXTREC i den ældste
      daglige måling i vinduet) / dage imellem; dage tilbage = (grænse − NEXTREC) / forbrug pr. dag. Målingerne er SQLInsights
      egne (insight.AxSequenceSamples, én pr. serie pr. dag, gemt i HourlyDays = 400 dage). Manuelle, cykliske og spærrede
      serier springes over. Højst 25 fund pr. database.

    Rettigheder:  Valgfri AX-læseadgang, kun SELECT (db/permissions/grant-dynamics-ax-read.sql):
                    Axapta 3.0:        GRANT SELECT ON [bmssa].[NUMBERSEQUENCETABLE] TO [<agentens bruger>];
                                       GRANT SELECT ON [bmssa].[NUMBERSEQUENCEREFERENCE] TO [<agentens bruger>];   (valgfri)
                    AX 4.0/2009:       samme tabeller i [dbo]
                    AX 2012/F&O:       GRANT SELECT ON [dbo].[NUMBERSEQUENCETABLE] TO [<agentens bruger>];
                                       GRANT SELECT ON [dbo].[NUMBERSEQUENCESCOPE] TO [<agentens bruger>];         (valgfri: firma)
                                       GRANT SELECT ON [dbo].[NUMBERSEQUENCEREFERENCE] TO [<agentens bruger>];     (valgfri)
                  Mangler NUMBERSEQUENCETABLE, er reglen "ikke målbar" med den nøjagtige GRANT for databasen.
    Versioner:    SQL Server 2005 og nyere (ikke 2000). Axapta 3.0: verificeret mod en kundes skema (schema-ax30.tsv).
                  AX 4.0, AX 2009, AX 2012 og F&O: baseret på Microsofts dokumenterede skema – ikke verificeret mod kundedata.
    Læsning:      Kun SELECT med TOP (de mest brugte først), READ COMMITTED med SET LOCK_TIMEOUT 2000 (SNAPSHOT, når databasen
                  tillader det), aldrig NOLOCK, i AX-databasen via [db].sys.sp_executesql. Kun i databaser genkendt som AX og
                  valgt til overvågning.
