In this section, we provide guides and references to use the SAP ERP connector.
Configure and schedule SAP ERP metadata workflow externally:

* [Requirements](#requirements)
* [Metadata Ingestion](#metadata-ingestion)
* [dbt Integration](#dbt-integration)

## How to Run the Connector Externally

To run the Ingestion via the UI you'll need to use the OpenMetadata Ingestion Container, which comes shipped with
custom Airflow plugins to handle the workflow deployment.

If, instead, you want to manage your workflows externally on your preferred orchestrator, you can check
the following docs to run the Ingestion Framework **anywhere**.

<Columns cols={2}>
  <Card title="External Schedulers" href="/v1.12.x/deployment/ingestion">
    Get more information about running the Ingestion Framework Externally
  </Card>
</Columns>

## Requirements

<Card title="OpenMetadata 1.1 or later" href="/v1.12.x/deployment">
  To deploy OpenMetadata, check the Deployment guides.
</Card>

To ingest the SAP ERP metadata, CDS Views and OData services need to be setup to efficiently expose SAP data. To achieve this, data must be exposed via RESTful interfaces.
Follow the guide [here](/v1.12.x/connectors/database/sap-erp/setup-sap-apis) to setup the APIs.

### Python Requirements

<Tip>
  We have support for Python versions **3.9-3.11**
</Tip>

To run the SAP ERP ingestion, you will need to install:

```bash theme={null}
pip3 install "openmetadata-ingestion[sap-erp]"
```

## Metadata Ingestion

All connectors are defined as JSON Schemas.
[Here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/entity/services/connections/database/sapErpConnection.json)
you can find the structure to create a connection to SAP ERP.
In order to create and run a Metadata Ingestion workflow, we will follow
the steps to create a YAML configuration able to connect to the source,
process the Entities if needed, and reach the OpenMetadata server.
The workflow is modeled around the following
[JSON Schema](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/workflow.json)

### 1. Define the YAML Config

This is a sample config for SAP ERP:

<CodePreview>
  <ContentPanel>
    <ContentSection id={1} title="Source Configuration" lines="1-3">
      Configure the source type and service name for your SAP ERP connector.
    </ContentSection>

    <ContentSection id={2} title="Host Port" lines="7">
      **hostPort**: Host and port of the SAP ERP service. This specifies the host and port of the SAP ERP instance. It should be specified as a string in the format `https://hostname.com`.
    </ContentSection>

    <ContentSection id={3} title="API Key" lines="8">
      **apiKey**: API Key to authenticate the SAP ERP APIs
    </ContentSection>

    <ContentSection id={4} title="Database Name" lines="9">
      **databaseName**: In OpenMetadata, the Database Service hierarchy works as follows:
      `Database Service > Database > Schema > Table`
      In the case of SAP ERP, we won't have a Database as such. If you'd like to see your data in a database named something other than `default`, you can specify the name in this field.
    </ContentSection>

    <ContentSection id={5} title="Database Schema" lines="10">
      **databaseSchema**: In OpenMetadata, the Database Service hierarchy works as follows:
      `Database Service > Database > Schema > Table`
      In the case of SAP ERP, we won't have a Database Schema as such. If you'd like to see your data in a database schema named something other than `default`, you can specify the name in this field.
    </ContentSection>

    <ContentSection id={6} title="Pagination Limit" lines="11">
      **paginationLimit**: Pagination limit used while querying the SAP ERP API for fetching the entities.
    </ContentSection>

    <ContentSection id={7} title="SSL Configuration" lines="13">
      #### Advanced Configuration

      The sslConfig and sslMode are used to configure the SSL (Secure Sockets Layer) connection between your application and the SAP ERP server.

      **caCertificate**: This is the path to the CA (Certificate Authority) certificate file. This file is used to verify the server's certificate.

      **sslMode**: This field controls whether a secure SSL/TLS connection will be negotiated with the server. Available modes: disable, allow, prefer, require, verify-ca, verify-full.
    </ContentSection>

    <ContentSection id={8} title="Connection Options" lines="14">
      **Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to database during the connection. These details must be added as Key-Value pairs.
    </ContentSection>

    <ContentSection id={9} title="Connection Arguments" lines="15">
      **Connection Arguments (Optional)**: Enter the details for any additional connection arguments such as security or protocol configs that can be sent to database during the connection. These details must be added as Key-Value pairs.

      * In case you are using Single-Sign-On (SSO) for authentication, add the `authenticator` details in the Connection Arguments as a Key-Value pair as follows: `"authenticator" : "sso_login_url"`
    </ContentSection>

    <ContentSection id={10} title="Source Config" lines="19-62">
      #### Source Configuration - Source Config

      The `sourceConfig` is defined [here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/databaseServiceMetadataPipeline.json):

      <div>
        **markDeletedTables**: To flag tables as soft-deleted if they are not present anymore in the source system.
      </div>

      <div>
        **markDeletedStoredProcedures**: Optional configuration to soft delete stored procedures in OpenMetadata if the source stored procedures are deleted. Also, if the stored procedures is deleted, all the associated entities like lineage, etc., with that stored procedures will be deleted.

        **markDeletedSchemas**: Optional configuration to soft delete schemas stored in OpenMetadata if the source schema is deleted. Setting this flag to true will only keep filtered schema and delete any other schemas that do not match schemaFilterPattern or do not exist at source.

        **markDeletedDatabases**: Additional optional configuration for soft deletion, providing granular option to select which particular entities should be deleted.

        **includeTables**: true or false, to ingest table data. Default is true.
      </div>

      <div>
        **includeViews**: true or false, to ingest views definitions.
      </div>

      <div>
        **includeTags**: Optional configuration to toggle the tags ingestion.
      </div>

      <div>
        **includeOwners**: Set the 'Include Owners' toggle to control whether to include owners to the ingested entity if the owner email matches with a user stored in the OM server as part of metadata ingestion. If the ingested entity already exists and has an owner, the owner will not be overwritten.
      </div>

      <div>
        **includeStoredProcedures**: Optional configuration to toggle the Stored Procedures ingestion.
      </div>

      <div>
        **includeDDL**: Optional configuration to toggle the DDL Statements ingestion.
      </div>

      <div>
        **overrideMetadata** *(boolean)*: Set the 'Override Metadata' toggle to control whether to override the existing metadata in the OpenMetadata server with the metadata fetched from the source. If the toggle is set to true, the metadata fetched from the source will override the existing metadata in the OpenMetadata server. If the toggle is set to false, the metadata fetched from the source will not override the existing metadata in the OpenMetadata server. This is applicable for fields like description, tags, owner and displayName.
      </div>

      <div>
        **queryLogDuration**: Configuration to tune how far we want to look back in query logs to process Stored Procedures results.
      </div>

      <div>
        **queryParsingTimeoutLimit**: Configuration to set the timeout for parsing the query in seconds.
      </div>

      <div>
        **useFqnForFiltering**: Regex will be applied on fully qualified name (e.g service\_name.db\_name.schema\_name.table\_name) instead of raw name (e.g. table\_name).
      </div>

      <div>
        **databaseFilterPattern**, **schemaFilterPattern**: Note that the filter supports regex as include or exclude. You can find examples [here](/connectors/ingestion/workflows/metadata/filter-patterns/database)
      </div>

      <div>
        **tableFilterPattern**: Note that the filter supports regex as include or exclude. You can find examples [here](/connectors/ingestion/workflows/metadata/filter-patterns/table)
      </div>

      <div>
        **threads (beta)**: The number of threads to use when extracting the metadata using multithreading.
      </div>

      <div>
        **databaseMetadataConfigType** *(string)*: Database Source Config Metadata Pipeline type.
      </div>

      <div>
        **incremental (beta)**: Incremental Extraction configuration. Currently implemented for:

        * [BigQuery](/connectors/ingestion/workflows/metadata/incremental-extraction/bigquery)
        * [Redshift](/connectors/ingestion/workflows/metadata/incremental-extraction/redshift)
        * [Snowflake](/connectors/ingestion/workflows/metadata/incremental-extraction/snowflake)
      </div>
    </ContentSection>

    <ContentSection id={11} title="Sink Configuration" lines="63-65">
      To send the metadata to OpenMetadata, it needs to be specified as `type: metadata-rest`.
    </ContentSection>

    <ContentSection id={12} title="Workflow Configuration" lines="66-82">
      <div>
        The main property here is the `openMetadataServerConfig`, where you can define the host and security provider of your OpenMetadata installation.
      </div>

      <div>
        **Logger Level**

        You can specify the `loggerLevel` depending on your needs. If you are trying to troubleshoot an ingestion, running with `DEBUG` will give you far more traces for identifying issues.
      </div>

      <div>
        **JWT Token**

        JWT tokens will allow your clients to authenticate against the OpenMetadata server. To enable JWT Tokens, you will get more details [here](/deployment/security/enable-jwt-tokens).

        You can refer to the JWT Troubleshooting section [link](/deployment/security/jwt-troubleshooting) for any issues in your JWT configuration.
      </div>

      <div>
        **Store Service Connection**

        If set to `true` (default), we will store the sensitive information either encrypted via the Fernet Key in the database or externally, if you have configured any [Secrets Manager](/deployment/secrets-manager).

        If set to `false`, the service will be created, but the service connection information will only be used by the Ingestion Framework at runtime, and won't be sent to the OpenMetadata server.
      </div>

      <div>
        **SSL Configuration**

        If you have added SSL to the [OpenMetadata server](/deployment/security/enable-ssl), then you will need to handle the certificates when running the ingestion too. You can either set `verifySSL` to `ignore`, or have it as `validate`, which will require you to set the `sslConfig.caCertificate` with a local path where your ingestion runs that points to the server certificate file.

        Find more information on how to troubleshoot SSL issues [here](/deployment/security/enable-ssl/ssl-troubleshooting).
      </div>

      <div>
        **ingestionPipelineFQN**

        Fully qualified name of ingestion pipeline, used to identify the current ingestion pipeline.
      </div>

### 2. Run with the CLI

First, we will need to save the YAML file. Afterward, and with all requirements installed, we can run:

```bash theme={null}
metadata ingest -c <path-to-yaml>
```

Note that from connector to connector, this recipe will always be the same. By updating the YAML configuration,
you will be able to extract metadata from different sources.

## Securing SAP ERP Connection with SSL in OpenMetadata

To configure SSL for secure connections between OpenMetadata and a Redshift database, Redshift offers various SSL modes, each providing different levels of connection security.
When running the ingestion process externally, specify the SSL mode to be used for the Redshift connection, such as `prefer`, `verify-ca`, `allow`, and others. Once you've chosen the SSL mode, provide the CA certificate for SSL validation (`caCertificate`). Only the CA certificate is required for SSL validation in Redshift.

```yaml theme={null}
      sslMode: disable #allow prefer require verify-ca verify-full
      sslConfig:
            caCertificate: "/path/to/ca/certificate"
```
