# Table 1500 "Workflow Buffer"

> Table 1500 "Workflow Buffer" in Base Application (System.Automation). 8 fields, 3 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/WorkflowBuffer.Table.al) · facts from BC29

Learn documents this table through its pages: [Page 1500 "Workflows"](../page/1500.md) (5 Learn pages), [Page 1505 "Workflow Templates"](../page/1505.md) (1).

## Properties

| Property | Value |
|---|---|
| Caption | Workflow Buffer |
| 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 | Category Code | Code[20] | Specifies the workflow type, such as Administration or Finance. <small>via [Page 1500 "Workflows"](../page/1500.md)</small> | TableRelation [Table 1508 "Workflow Category"](../table/1508.md) ("Workflow Category".Code); DataClassification SystemMetadata |
| 2 | Workflow Code | Code[20] | Specifies the workflow that the workflow step belongs to. <small>via [Page 1500 "Workflows"](../page/1500.md)</small> | TableRelation Workflow.Code; DataClassification SystemMetadata |
| 3 | Indentation | Integer | — | DataClassification SystemMetadata |
| 4 | Description | Text[100] | Specifies a description of the workflow. <small>via [Page 1500 "Workflows"](../page/1500.md)</small> | not editable; DataClassification SystemMetadata |
| 6 | Template | Boolean | — | FlowField: lookup(Workflow.Template where(Code = field("Workflow Code"))); not editable |
| 7 | Enabled | Boolean | Specifies if the workflow is enabled. <small>via [Page 1500 "Workflows"](../page/1500.md)</small> | FlowField: lookup(Workflow.Enabled where(Code = field("Workflow Code"))); not editable |
| 8 | External Client ID | Guid | — | FlowField: lookup("Workflow Webhook Subscription"."Client Id" where("WF Definition Id" = field("Workflow Code"), Enabled = const(true))); not editable |
| 9 | External Client Type | Text[50] | — | FlowField: lookup("Workflow Webhook Subscription"."Client Type" where("WF Definition Id" = field("Workflow Code"), Enabled = const(true))); not editable |

## Keys

- Key1: Category Code, Workflow Code (clustered)

## Procedures

- `InitBufferForWorkflows(var TempWorkflowBuffer: Record "Workflow Buffer" temporary)`
- `InitBufferForTemplates(var TempWorkflowBuffer: Record "Workflow Buffer" temporary)`
- `CopyWorkflow(WorkflowBuffer: Record "Workflow Buffer")`

Plus 4 local procedures.

## Triggers

## Relations

- Enabled: CalcFormula [Table 1501 "Workflow"](../table/1501.md)
- Template: CalcFormula [Table 1501 "Workflow"](../table/1501.md)
- Category Code: TableRelation [Table 1508 "Workflow Category"](../table/1508.md)
- External Client ID: CalcFormula [Table 469 "Workflow Webhook Subscription"](../table/469.md)
- External Client Type: CalcFormula [Table 469 "Workflow Webhook Subscription"](../table/469.md)

## Pages and codeunits on this table

- [Page 1500 "Workflows"](../page/1500.md) (source table)
- [Page 1505 "Workflow Templates"](../page/1505.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.

- [Page 1501 "Workflow"](../page/1501.md) (1 call: `CopyWorkflow → (object)`)

## 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 Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
