Functions

Overview

SAP function modules allow users to encapsulate and reuse global functions in the SAP system. Functions are managed in a central function library. The SAP system contains several predefined function modules that can be called. Users may also create custom functions based on business requirements. SAP functions have input variables, output variables, changing variables and exceptions. Variables can be a single value, a dictionary (referred to as a "structure") or a list of dictionaries (referred to as a "table"). Function modules are bi-directional: they can both extract data and write back data to an SAP system.

Prerequisites

In order to extract function results, the Foundry technical user needs the following authorization roles (or a custom role that has same authorization objects as the following roles):

/PALANTIR/SERVICE_USER
/PALANTIR/CONTENT_FUNCTION_ALL
Any particular authorization role or object required to run the specific SAP function

Configuration

The Connector can only extract data from functions having at least one tabular output parameter. If the function returns more than one output parameter, the user will need to specify which output to write to the Foundry dataset using the paramName parameter.

Simple example

This example sync configuration returns the USERLIST parameter of the BAPI_USER_GETLIST function:

Copied!1
2
3
4
type: magritte-sap-source-adapter
sapType: function
obj: BAPI_USER_GETLIST
paramName: USERLIST

Using input parameters

Input parameters for functions requiring them can be defined using the inputParams. Input parameters can have different types:

single value type

Copied!1
2
inputParams:
  singleValueType_key : 'value'

structure type

Copied!1
2
inputParams:
  structureType_key : '{"key1": "value1", "key2": "value2"}'

table type

Copied!1
2
inputParams:
  tableType_key : '[{"key1": "value1", "key2": "value2"},{"key1": "value3", "key2": "value4"}]'

In the following example sync configuration, the function EM_GET_NUMBER_OF_ENTRIES expects an input parameter IT_TABLES of table type:

Copied!1
2
3
4
5
6
type: magritte-sap-source-adapter
sapType: function
obj: EM_GET_NUMBER_OF_ENTRIES
inputParams:
  IT_TABLES: '[{"TABNAME":"TSTC"}]'
paramName: IT_TABLES
