# Table 30432 "User Permissions Buffer"

> Table 30432 "User Permissions Buffer" in Base Application (System.Security.AccessControl). 9 fields, 2 public procedures. Introduced in BC28, still in BC30.

Base Application · System.Security.AccessControl · BC28-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/System/Permissions/UserPermissionsBuffer.Table.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Caption | User Permissions Buffer |
| TableType | Temporary |
| DataClassification | CustomerContent |

## Fields

Explanation: the field's ToolTip in the code; without one, the ToolTip of a page control bound to the field (marked via the page); without that, its Caption (marked caption) when that differs from the name.

| No. | Name | Type | Explanation | Notes |
|---|---|---|---|---|
| 1 | User Security ID | Guid | — |  |
| 2 | Role ID | Code[20] | — | TableRelation "Aggregate Permission Set"."Role ID" |
| 3 | Type | Option | — | OptionCaption: User,Security Group |
| 4 | SecurityGroupCode | Code[20] | Security Group Code <small>caption</small> |  |
| 5 | Company Name | Text[30] | — | TableRelation System.Environment.Company.Name |
| 6 | Role Name | Text[30] | — | FlowField: lookup("Aggregate Permission Set".Name where(Scope = field(Scope), "App ID" = field("App ID"), "Role ID" = field("Role ID"))) |
| 7 | Scope | Option | — | TableRelation "Aggregate Permission Set".Scope; OptionCaption: System,Tenant |
| 8 | App ID | Guid | — | TableRelation "Aggregate Permission Set"."App ID" |
| 9 | App Name | Text[250] | — | FlowField: lookup("Aggregate Permission Set"."App Name" where(Scope = field(Scope), "App ID" = field("App ID"), "Role ID" = field("Role ID"))) |

## Keys

- Key1: User Security ID, Role ID, Type (clustered)

## Procedures

- `FillBuffer()`: Fills the buffer with user permission data from Access Control and Security Group Member records.
- `InsertRecord(var UserPermissionBuffer: Record "User Permissions Buffer"; AccessControl: Record "Access Control"; UserType: Option)`: Inserts an access control record into the user permissions buffer.

## Pages and codeunits on this table

- [Page 20769 "APIV2 - User Permission Sets"](../page/20769.md) (source table)

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 9031 "Security Group"](../codeunit/9031.md) (1 call: `FillBuffer → GetMembers`)

## Across versions

- Present in: BC28-30
- Changed (declaration) in: none

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "table", object_name: "User Permissions Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
