In Ssrs 2019, how does one interpret Subscriptions.InactiveFlags?

Question

In the Ssrs database catalog, how are you supposed to interpret the InactiveFlags column of the Subscriptions table?

Answer 1

I couldn't find anything really authoritative/complete out there on the 'Net (well, beyond "InactiveFlags = 0 means the subscription is enabled"). I perused the built-in sprocs/funcs in Ssrs, but except for DeliveryRemovedInactivateSubscription, they all just pass through whatever value they're given.

So I went and decompiled the ReportingServicesLibrary.dll (I used "dnSpy") and found the Microsoft.ReportingServices.Library.InActiveFlags enum. I've personally experienced "8" and "16" from past work with Ssrs 2012, so everything lines up. It's a bit-mask, defined as follows:

internal enum InActiveFlags
{
    Active, // 0
    DeliveryProviderRemoved, // 1
    SharedDataSourceRemoved, // 2
    MissingParameterValue = 4,
    InvalidParameterValue = 8,
    UnknownItemParameter = 16,
    MissingExtensionEncryptedSettings = 32,
    CachingNotEnabledOnItem = 64,
    DisabledByUser = 128
}

E.g.

--Find subs with invalid params ('cause someone made a breaking change to the report after the sub was created).
SELECT * FROM Subscriptions WHERE InactiveFlags & 8 != 0;
