SAP Source dbt Package (Docs)

What does this dbt package do?

• Materializes SAP staging tables that are intended to reproduce crucial source tables that funnel into important SAP reports.
• These tables will flow up to replicate SAP extractor reports that are provided in our transformation package, while not applying any renaming to the fields.
• These staging tables clean, test, and prepare your SAP data from Fivetran's SAP connectors, like LDP SAP Netweaver, HVA SAP or SAP ERP on HANA for analysis by doing the following:
  • Name columns for consistency across all packages and for easier analysis
  • Adds freshness tests to source data
  • Adds column-level testing where applicable. For example, all primary keys are tested for uniqueness and non-null values.
• Generates a comprehensive data dictionary of your sap data through the dbt docs site.
• These tables are designed to work simultaneously with our SAP transformation package.

How do I use the dbt package?

Step 1: Prerequisites

To use this dbt package, you must have the following:

• At least one Fivetran of the following SAP connectors:
  • LDP SAP Netweaver
  • HVA SAP
  • SAP ERP on HANA
• Within the connector, syncing the following respective tables into your destination:
  • bkpf
  • bseg
  • faglflexa
  • faglflext
  • kna1
  • lfa1
  • mara
  • pa0000
  • pa0001
  • pa0007
  • pa0008
  • pa0031
  • ska1
  • t001
  • t503
  • t880
• A BigQuery, Snowflake, Redshift, PostgreSQL, Databricks destination.

Databricks Dispatch Configuration

If you are using a Databricks destination with this package you will need to add the below (or a variation of the below) dispatch configuration within your dbt_project.yml. This is required for the package to accurately search for macros within the dbt-labs/spark_utils then the dbt-labs/dbt_utils packages respectively.

dispatch:
  - macro_namespace: dbt_utils
    search_order: ['spark_utils', 'dbt_utils']

Step 2: Install the package

If you are not using the SAP transformation package, include the following sap_source package version in your packages.yml file.

TIP: Check dbt Hub for the latest installation instructions or read the dbt docs for more information on installing packages.

packages:
  - package: fivetran/sap_source
    version: [">=0.1.0", "<0.2.0"]

Step 3: Define database and schema variables

By default, this package runs using your destination and the sap schema. If this is not where your SAP data is (for example, if your sap schema is named sap_fivetran), add the following configuration to your root dbt_project.yml file:

vars:
    sap_database: your_destination_name
    sap_schema: your_schema_name 

(Optional) Step 4: Additional configurations

Change the build schema

By default, this package builds the SAP staging models within a schema titled (<target_schema> + stg_sap) in your destination. If this is not where you would like your sap staging data to be written to, add the following configuration to your root dbt_project.yml file:

models:
    sap_source:
      +schema: my_new_schema_name # leave blank for just the target_schema

Change the source table references

If an individual source table has a different name than the package expects, add the table name as it appears in your destination to the respective variable:

IMPORTANT: See this project's dbt_project.yml variable declarations to see the expected names.

vars:
    # For all SAP source tables
    sap_<default_source_table_name>_identifier: your_table_name 

(Optional) Step 5: Orchestrate your models with Fivetran Transformations for dbt Core™
