> Table 1520 "Workflow Event" in Base Application (System.Automation). 7 fields, 5 public procedures. Present since at least BC23, still in BC30, changed in BC24.

Base Application · System.Automation · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/System/Workflow/WorkflowEvent.Table.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Caption | Workflow Event |
| DataClassification | CustomerContent |
| Permissions | TableData "Workflow Step Argument" = rm |

## 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 | Function Name | Code[128] | — | NotBlank |
| 2 | Table ID | Integer | — | TableRelation AllObjWithCaption."Object ID" where("Object Type" = const(Table)) |
| 3 | Description | Text[250] | Specifies the workflow event. <small>via [Page 1520 "Workflow Events"](../page/1520.md)</small> |  |
| 4 | Request Page ID | Integer | — | TableRelation AllObjWithCaption."Object ID" where("Object Type" = const(Report)) |
| 5 | Dynamic Req. Page Entity Name | Code[20] | — | TableRelation [Table 1515 "Dynamic Request Page Entity"](../table/1515.md) ("Dynamic Request Page Entity".Name where("Table ID" = field("Table ID"))) |
| 6 | Used for Record Change | Boolean | — |  |
| 7 | Independent | Boolean | — |  |

## Keys

- Key1: Function Name (clustered)
- Key2: Independent, Description

## Procedures

- `RunRequestPage(var ReturnFilters: Text; Filters: Text): Boolean`
- `CreateDefaultRequestPageFilters(): Text`
- `HasPredecessors(): Boolean`
- `MakeDependentOnAllEvents()`
- `MakeIndependent()`

Plus 2 local procedures.

## Triggers

OnDelete

## Relations

- lookup page [Page 1520 "Workflow Events"](../page/1520.md)
- Dynamic Req. Page Entity Name: TableRelation [Table 1515 "Dynamic Request Page Entity"](../table/1515.md)

## Referenced by

5 fields in 4 objects relate to this table (TableRelation or CalcFormula).

- [Table 1509 "WF Event/Response Combination"](../table/1509.md): Function Name, Predecessor Function Name
- [Table 1502 "Workflow Step"](../table/1502.md): Function Name
- [Table 1504 "Workflow Step Instance"](../table/1504.md): Function Name
- [Table 1507 "Workflow Step Buffer"](../table/1507.md): Event Description

## Pages and codeunits on this table

- [Page 1520 "Workflow Events"](../page/1520.md) (source table)
- [Page 1542 "WF Event/Event Comb. Matrix"](../page/1542.md) (source table)
- [Page 1543 "WF Event/Response Comb. Matrix"](../page/1543.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 1530 "Request Page Parameters Helper"](../codeunit/1530.md) (5 calls: `CreateDefaultRequestPageFilters → BuildDynamicRequestPage`, `CreateDefaultRequestPageFilters → GetViewFromDynamicRequestPage`, `RunDynamicRequestPage → BuildDynamicRequestPage`, …)
- [Codeunit 1501 "Workflow Management"](../codeunit/1501.md) (1 call: `OnDelete → ClearSupportedCombinations`)
- [Codeunit 1520 "Workflow Event Handling"](../codeunit/1520.md) (1 call: `MakeDependentOnAllEvents → AddEventPredecessor`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24

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: "Workflow Event")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
