| SourceTable | Use Case Tree Node |
| PageType | List |
| UsageCategory | Lists |
| ApplicationArea | Basic, Suite |

## Fields on this page

Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| Control1 | Code | [Code](../table/20295.md#fields) | Specifies the code for the use case tree node. |
|  | Name | [Name](../table/20295.md#fields) | Specifies a descriptive name for the use case tree node. |
|  | Node Type | [Node Type](../table/20295.md#fields) | Specifies the purpose of the use case tree node. |
|  | Tax Entity Name | `TaxEntityName` | Specifies the source table considered for computing tax components. |
|  | Condition | `StrSubstNo(ConditionLbl, ConditionText)` | Specifies the condition to execute the use case. |
|  | Use Case Name | `UseCaseName` | Specifies the name of the attached use case. |
|  | Blocked | [Blocked](../table/20295.md#fields) | Specifies that the related record is blocked from being used in use case execution. |
|  | Is Tax Type Root | [Is Tax Type Root](../table/20295.md#fields) | Specifies that the tree node is root of the tax type. |
|  | Tax Type | [Tax Type](../table/20295.md#fields) | Specifies the tax type for the below heirarchy. |

## Actions

| Group | Action | ToolTip | Runs |
|---|---|---|---|
| Functions | Indent Nodes | Indent nodes between a Begin and the matching End one level to make the list easier to read. | [Codeunit 20299 "Use Case Tree-Indent"](../codeunit/20299.md) |
|  | Import Use Case from Library | Imports the Use Case from the set of library of use cases. |  |
|  | Export Nodes | Indent nodes between a Begin and the matching End one level to make the list easier to read. |  |
|  | Import Nodes | Indent nodes between a Begin and the matching End one level to make the list easier to read. |  |

## Procedures

2 local procedures, no public ones.

## Triggers

OnAfterGetRecord, OnAfterGetCurrRecord

## Relations

- source table [Table 20295 "Use Case Tree Node"](../table/20295.md)

## 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 20130 "App Object Helper"](../codeunit/20130.md) (1 call: `FormatLine → GetObjectName`)

## Across versions

- Present in: BC29-30
- 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: "page", object_name: "Use Case Tree")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
