| No. | Name | Type | Explanation | Notes |
|---|---|---|---|---|
| 1 | Source Sql Table Name | Text[128] | Specifies the name of the source SQL table to be replicated. The name must match exactly the name of the destination table in SQL. |  |
| 2 | Destination Sql Table Name | Text[128] | Specifies the name of the destination SQL table in the cloud environment. The name must match exactly the name of the destination table in SQL. |  |
| 3 | Company Name | Text[30] | Specifies the company name associated with this table mapping. The value should be blank if the table is per-database. |  |
| 4 | Table Name | Text[128] | Specifies the name of the table. For example, "Customer" or "Sales Header". |  |
| 5 | Preserve Cloud Data | Boolean | Specifies whether to preserve existing data in the cloud during replication.

## Ask your agent

Procedure bodies are not stored here (D10). 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: "Replication Table Mapping")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
