## Properties

| Property | Value |
|---|---|
| Caption | New Synthetic Relation |
| SourceTable | Synth. Relation Mapping Buffer |
| PageType | NavigatePage |

## 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 |
|---|---|---|---|
| BannerStandard | MediaResourceStandardReference | `MediaResourcesStandard."Media Reference"` | — |
| BannerDone | MediaResourceDoneReference | `MediaResourcesDone."Media Reference"` | — |
| Step0 | Native Dataverse Table | `TempSyntheticRelationToCreate."Syncd. Table Name"` | Specifies the native Dataverse table that will be used to create the relation. |
|  | Virtual Dataverse Table | `TempSyntheticRelationToCreate."Virtual Table Caption"` | Specifies the virtual Dataverse table that will be used to create the relation. |
| Advanced | Virtual Table API Page Id | `TempSyntheticRelationToCreate."Virtual Table API Page Id"` | For the selected virtual table, specifies the API page that will be used to browse the related fields. |
| Step1 | FieldsMatchingInstructions | label | — |
|  | How many fields connect the tables? | `NFieldsMatching` | Specifies the number of fields in the native and virtual tables that will be used to create the relation. |
| FieldsToMatch | Syncd. Field 1 Name | [Syncd. Field 1 Name](../table/5378.md#fields) | Specifies the column in the native Dataverse table that will be used to create the relation. |
|  | Virtual Table Column 1 Name | [Virtual Table Column 1 Caption](../table/5378.md#fields) | Specifies the column in the virtual Dataverse table that will be used to create the relation. This must be the logical name of the Dataverse virtual table's column. |
| Step2 | We couldn't find a key for the selected columns of the native Dataverse table selected. A key is being created. Use the action "Refresh" to update the status. | label | — |

## Procedures

- `SetExistingBCTableRelations(var TempSynthRelationMappingBuffer: Record "Synth. Relation Mapping Buffer")` (internal)

Plus 14 local procedures.

## Triggers

OnInit, OnOpenPage

## Relations

- source table [Table 5378 "Synth. Relation Mapping Buffer"](../table/5378.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 7202 "Synthetic Relations"](../codeunit/7202.md) (2 calls: `NextPage → CreateAlternateKeyForColumns`, `NextPage → GetExistingAlternateKeyName`)
- [Codeunit 4030 "Client Type Management"](../codeunit/4030.md) (1 call: `LoadTopBanners → GetCurrentClientType`)

## Across versions

- Present in: BC24-30
- 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: "New Synthetic Relation Wiz.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
