PLANTA project and SAP

Information

• This page describes the technical connection of PLANTA project to an SAP system. It is relevant if you are setting up an SAP interface based on the universal interface of PLANTA link.

• The data exchange and the functional logic is explained in the Introduction to PLANTA link and Interfaces page.

• PLANTA provides several SAP standard interfaces which can be used as a template for setting up individual SAP interfaces.

General

Information

• PLANTA project communicates with the SAP system via RFC calls (Remote Function Call).

• To do this, the worker integrates the SAP NetWeaver RFC client library via the pyrfc Python module.

Setup

Requirements

• Starting from Worker S 39.2.5 the worker image contains the pyrfc Python module. It is based on PyRFC.

• The libraries of the SAP NetWeaver RFC SDK 7.50 for Linux are not contained in the image. They are provided by the customer.

• The worker container must reach the SAP system via the network.

Note on the implementation

• The worker finds the SDK libraries via the LD_LIBRARY_PATH environment variable. The path /planta/dlls must be listed first.

• SAPNWRFC_HOME is not needed.

Procedure

• Store the SDK libraries in a directory and and mount this directory as a volume in the worker container, e.g., under /opt/sap/nwrfcsdk/lib.

  • For a single-instance environment, this is done in docker-compose.yml under volumes of the worker service.

  • For an orchestrated environment, this is done in the Helm values under worker.additionalVolumes and worker.additionalVolumeMounts.

• Set the environment variable LD_LIBRARY_PATH of the worker container to /planta/dlls:/opt/sap/nwrfcsdk/lib.

  • For a single-instance environment, this is done in docker-compose.yml under environment of the worker service.

  • For an orchestrated environment, this is done in the Helm values under worker.env.

• Restart the worker container.

Use

Information

• The Python module pyrfc can be included in any Python macro in PLANTA Project using import pyrfc.
