# What does Atlan crawl from SAP Datasphere? 

Atlan extracts metadata for Databases, Schemas, Tables, Views, Analytic models, Columns, and Replication Flows from SAP Datasphere and maps each property to its internal asset model. The tables below list which SAP Datasphere properties are read and how they appear on the corresponding Atlan asset.

Once you have [crawled SAP Datasphere](https://docs.atlan.com/llms/connectors/sap-datasphere/crawl-sap-datasphere/llms.txt), you can [use connector-specific filters](https://docs.atlan.com/llms/catalog/discovery/use-the-filters-menu/llms.txt) for quick asset discovery.

## Databases

SAP Datasphere is backed by a single database. Atlan maps the top-level catalog as `DEFAULT` to its `Database` asset type, and maps each SAP Datasphere space to the `Schema` asset type.

| Source property | Atlan property | Where in Atlan |
| --- | --- | --- |
| `DEFAULT` (catalog) | `name` | asset preview and profile, overview sidebar |
| Schema count | `schemaCount` | asset filters |

## Schemas

Atlan maps each SAP Datasphere space to its `Schema` asset type.

| Source property | Atlan property | Where in Atlan |
| --- | --- | --- |
| Space name | `name` | asset preview and profile, overview sidebar |
| Table count | `tableCount` | asset preview and profile |
| View count | `viewsCount` | asset preview and profile |
| `DEFAULT` (catalog) | `databaseName` | asset preview and profile, overview sidebar |

## Tables

Atlan maps tables from SAP Datasphere to its `Table` asset type.

| Source property | Atlan property | Where in Atlan |
| --- | --- | --- |
| Table name | `name` | asset preview and profile, overview sidebar |
| Table comment | `description` | asset profile, overview sidebar |
| Column count | `columnCount` | asset preview and profile, overview sidebar |
| Row count | `rowCount` | asset preview and profile, overview sidebar |
| Table size | `sizeBytes` | asset preview and profile, overview sidebar |

## Views

Atlan maps SQL views from SAP Datasphere to its `View` asset type.

| Source property | Atlan property | Where in Atlan |
| --- | --- | --- |
| View name | `name` | asset preview and profile, overview sidebar |
| View comment | `description` | asset profile, overview sidebar |
| Column count | `columnCount` | asset preview and profile, overview sidebar |
| View definition | `definition` | asset profile and overview sidebar |

## Analytic models

Atlan catalogs SAP Datasphere analytic models as its `View` asset type. Their fields (measures, dimensions, and attributes) are cataloged as columns.

| Source property | Atlan property | Where in Atlan |
| --- | --- | --- |
| Analytic model name | `name` | asset preview and profile, overview sidebar |
| Column count | `columnCount` | asset preview and profile, overview sidebar |

## Columns

Atlan maps columns from SAP Datasphere to its `Column` asset type. This includes the columns of tables and views, and the fields of analytic models (measures, dimensions, and attributes).

| Source property | Atlan property | Where in Atlan |
| --- | --- | --- |
| Column name | `name` | asset profile and filter, overview sidebar |
| Column comment | `description` | asset profile and filter, overview sidebar |
| Column position | `order` | parent asset profile |
| Data type | `dataType` | asset preview and filter, overview sidebar, parent asset profile |
| Primary key flag | `isPrimary` | asset preview and filter, overview sidebar, parent asset profile |
| Nullability | `isNullable` | API only |

## Replication flows

Atlan catalogs replication flows as a first-class asset so you can see how data is replicated into SAP Datasphere from source systems. Replication flows also drive [upstream source lineage](https://docs.atlan.com/llms/connectors/sap-datasphere/how-atlan-connects-to-sap-datasphere/llms.txt).

| Source property | Atlan property | Where in Atlan |
| --- | --- | --- |
| Replication flow name | `name` | asset preview and profile, overview sidebar |
| Source connection | source connection attribute | asset profile |
| Target connection | target connection attribute | asset profile |
| Load type | load type attribute | asset profile |
| Dataset count | dataset count attribute | asset profile |
