  • In ABP Framework, you can’t “assign a module to a tenant” in the sense of dynamically loading/unloading a .NET module per tenant at runtime. ABP modules are part of the application and are loaded on startup.
  • What you can do is enable/disable functionality per tenant by using:
    1. Feature Management (recommended for “module/feature toggle per tenant”), and/or
    2. Permission Management (grant/revoke permissions per tenant/role).

  1) Use Feature Management to enable “HomeServices” only for Tenant A

  1. Define a feature (e.g., MyApp.HomeServices) and use it to guard your “Home services” UI/API.
  2. Assign the feature value per tenant (Host side): SaaS → Tenants → Actions → Features (or similar UI depending on your template).
  3. Check the feature in code (application service) and/or in UI menu contributors to hide/disable items.

  Example (application service guard):

  using Volo.Abp;
  using Volo.Abp.Application.Services;
  using Volo.Abp.Features;
  
  public class HomeServiceAppService : ApplicationService
  {
      private readonly IFeatureChecker _featureChecker;
  
      public HomeServiceAppService(IFeatureChecker featureChecker)
      {
          _featureChecker = featureChecker;
      }
  
      public async Task DoSomethingAsync()
      {
          if (!await _featureChecker.IsEnabledAsync("MyApp.HomeServices"))
          {
              throw new AbpAuthorizationException("Home services is not enabled for this tenant.");
          }
  
          // ...
      }
  }
  

  This approach makes the feature actually unavailable for tenants where it’s disabled (not just “permission disabled”).

  2) Why tenant admin sees permissions but they are disabled

  That behavior typically happens when the current user does not have the right to grant/revoke those permissions (permission grant/revoke is itself protected). So they can “see” permissions but cannot change them. If you want only host to manage what tenants can use, keep it that way and manage tenant permissions/features from the host side.

  3) If you only need “Home vs Business” access control (no feature toggles)

  Define permissions and use ABP’s multi-tenancy side for permissions (Host, Tenant, Both) and then grant permissions to tenant roles accordingly. This is good for authorization, but it’s not the same as “module enable/disable”.

  Hi,

  For per-tenant module control, you want Feature Management, not Permission Management. Permission = what a role is allowed to do; Feature = what a tenant/edition can use. Your case is the latter, and ABP has this OOTB.

  Here's the full flow:

  1. Define your features

  public class MyAppFeatureDefinitionProvider : FeatureDefinitionProvider
  {
      public override void Define(IFeatureDefinitionContext context)
      {
          var group = context.AddGroup("MyApp", L("Features:MyApp"));
  
          group.AddFeature(
              "MyApp.HomeServices",
              defaultValue: "false",
              displayName: L("Features:HomeServices"),
              valueType: new ToggleStringValueType());
  
          group.AddFeature(
              "MyApp.BusinessServices",
              defaultValue: "false",
              displayName: L("Features:BusinessServices"),
              valueType: new ToggleStringValueType());
      }
  
      private static LocalizableString L(string name)
          => LocalizableString.Create<MyAppResource>(name);
  }
  

  2. Protect the application services

  [RequiresFeature("MyApp.HomeServices")]
  public class HomeServicesAppService : ApplicationService, IHomeServicesAppService
  {
      // only reachable when the feature is enabled for the current tenant
  }
  

  Or inline inside a method:

  await FeatureChecker.CheckEnabledAsync("MyApp.HomeServices");
  

  3. Hide the menu item for tenants that don't have it

  context.Menu.AddItem(
      new ApplicationMenuItem("HomeServices", l["Menu:HomeServices"], "/home-services")
          .RequireFeatures("MyApp.HomeServices"));
  

  4. Assign per tenant — no code needed

  Login as host admin, go to Saas → Tenants → (the tenant) → Actions → Manage Features, toggle Home Services ON for Tenant A and leave Business Services OFF. Save. Tenant A now only sees/uses Home Services.

  About the "all disabled" permission screen your tenant admin sees — that's unrelated to the module toggle. It just means the logged-in tenant admin user doesn't have PermissionManagement.ManagePermissions granted, so the grid is read-only. But for module-level per-tenant control, features are the right tool, not permissions.
