# SAP S/4HANA Cloud Connector Reference
SAP S/4HANA is an enterprise resource planning (ERP) software used for application and IT infrastructure security, asset operation and maintenance, business planning and consolidation, logistics and order fulfillment, and more. This connector is based on the SAP S/4HANA OData API.
## Connections
To connect to a system, whether it is a source of data or the target where you are sending data, you must create a connection with that system’s required credentials. You typically connect to different systems within a flow and can reuse each connection every time you need to connect.
This system requires the following credential information for its connections: 

Connection Display Name
    
Enter a connection name that will help you remember the details of this connection. You can reuse connections multiple times in a single flow, and in more than one flow, and the credentials are hidden after you create the connection. Therefore, it’s helpful to provide a name that easily identifies this connection from others.
Only you can see the connection. Other users in your Composer app must create their own connections. 

Base URL
    
The URL for your SAP S/4HANA instance, for example, `https://{YourInstance}-api.s4hana.cloud.sap`. 

Username
    
The username that you use to log in to SAP S/4HANA. 

Password
    
The password that you use to log in to SAP S/4HANA.
## Triggers
Each flow starts with either a _scheduler_ or a _trigger_. Schedulers are set to a default frequency of 15 minutes. Triggers, such as "each time a new record is created", are defined by you and provide multiple options related to the data in your system.
Triggers use a polling process to actively check for new updates from an external system. The polling frequency is 15 seconds.
This system provides the following trigger options: 

On New or Updated Entity
    
Triggers when a new object of the record subtype is created or updated. Provide a value for the following fields:
  * **Entity type**


### Polling Frequency
For triggers in this connector, the **Polling Frequency** field is required. This field enables you to select how often Composer makes a request to the underling system API to look for changes to records in active flows. You can select a different polling frequency for each flow in your organization. With a shorter frequency, the flow executes more often; however, a shorter frequency consumes more API calls. For example, if you have an order management flow, you might require nearly real-time updates, which can be achieved with a 15-second polling interval (which equates to 5760 API calls per day). In contrast, if your flow updates a pricing catalog, you could poll the flow every hour (which equates to 24 API calls per day).
## Actions
After you connect to a system and define the trigger or configure a scheduler, you define the actions that the flow performs. For example, you can copy a record between different systems, such as Workday and Salesforce. The actions you can perform depend on which system you are connected to.
This system provides the following actions: 

Create Entity
    
Creates a record of the specified record type. Provide a value for the following fields:
  * **Entity type**



Get Entity
    
Retrieves a record of the specified record type. Provide a value for the following fields:
  * **Entity type**
  * **Entity key**



Update Entity
    
Updates a record of the specified record type. Provide a value for the following fields:
  * **Entity type**



Delete Entity
    
Deletes a record of the specified record type. Provide a value for the following fields:
  * **Entity type**
  * **Entity key**


## Custom Fields
Using MuleSoft Composer, you can access custom field values for actions and triggers that you set in the SAP S/4HANA record.
