Connection names must meet the following criteria:
- Connection names can use letters, numbers, or hyphens.
- Letters must be lower-case.
- Connection names must begin with a letter and end with a letter or number.
- Connection names cannot exceed 63 characters.
- Optionally, enter a Description for the connection instance.
- Service Account: Select a service account that has the required roles.
- To use the connection for event subscriptions, select Enable event subscription. Selecting
this, displays the following options:
- Enable event subscription with entity and actions: Select this option to use the connection for both event subscription and connector operations (entities and actions).
- Enable only event subscription: Select this option to use the connection only for event subscription. If you select this option, click Next, and then configure event subscription.
- Namespace: Specify the service namespace you want to retrieve data from. This is required if the service is not specified in the URL.
- Service: Specify the service you want to retrieve data from. This is required if the service is not specified in the URL.
- CustomUrlParams: Sspecify custom query string parameters that are included with the HTTP request. The parameters must be encoded as a query string in the following format:
field1=value1&field2=value2
. The values in the query string must be URL encoded. - Data Format: The data format to retrieve data in. Select either XML or JSON.
- Use Display Names: Boolean determining whether or not to use SAP labels.
- Optionally, configure the Connection node settings:
- Minimum number of nodes: Enter the minimum number of connection nodes.
- Maximum number of nodes: Enter the maximum number of connection nodes.
A node is a unit (or replica) of a connection that processes transactions. More nodes are required to process more transactions for a connection and conversely, fewer nodes are required to process fewer transactions. To understand how the nodes affect your connector pricing, see Pricing for connection nodes. If you don't enter any values, by default the minimum nodes are set to 2 (for better availability) and the maximum nodes are set to 50.
- Optionally, click + ADD LABEL to add a label to the Connection in the form of a key/value pair.
- Click NEXT.
- In the Destinations section, set the URL of your SAP Gateway environment or to the full URL of the OData service. For example format;
${ENVIRONMENT_URL}/sap/opu/odata/${NAMESPACE}/${SERVICE}/
and sample URL ishttps://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/
. Add any additional properties using the CustomUrlParams property.- Destination Type: Select a Destination Type.
- Select Host address from the list to specify the hostname or IP address of the destination.
- If you want to establish a private connection to your backend systems, select Endpoint attachment from the list, and then select the required endpoint attachment from the Endpoint Attachment list.
If you want to establish a public connection to your backend systems with additional security, you can consider configuring static outbound IP addresses for your connections, and then configure your firewall rules to allowlist only the specific static IP addresses.
To enter additional destinations, click +ADD DESTINATION.
