| Parameter Name | Data Type | Description | Default Value | Example | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Label* | String | Specify the name for the Snap. You can modify the default name to be more specific and meaningful, especially if you have more than one of the same Snaps in your Pipeline. | N/A | RFC Listener | |||||||||
| RFC Function Name* | String/Expression | Specify the name of the remote function corresponding to the RFC function on the SAP application. | N/A | X_SNAP_REMOTE_CALL | |||||||||
Gateway Properties | Use this field set to specify the gateway properties. These fields define the gateway location from where the Snap is listening. SAP uses the gateway mechanism to register and manage RFC servers. This field set contains the following fields:
| ||||||||||||
| Gateway Host* | String/Expression | Specify the host name of the SAP gateway service. | N/A | sap.cloud.com | |||||||||
| Gateway Service* | String/Expression | Specify the SAP gateway service in this format: sapgwNN, where NN represents integer values. | N/A | sapgw02 | |||||||||
| Program ID* | String/Expression | Specify the program ID of the server that is configured at the RFC destination. This ID is used to identify the RFC server that the gateway uses to register the server. | N/A | Snaplogic | |||||||||
| Connection Count* | String/Expression | Specify the count of the registered connections that are managed by the server instance. | 2 | 4 | |||||||||
| Max startup delay* | String/Expression | Specify the maximum number of seconds to wait between two successive server reconnect attempts.
| 2 | 300 | |||||||||
| Datetime Parameter As Text | Check boxCheckbox | Select this check box to import parameters with Date or Time data type, and to pass these parameters as a string. | Deselected | Selected | |||||||||
| Date conversion format | String/Expression | Specify the conversion format for the date data type. If a field is a string and if the Business Application Programming Interface (BAPI) requires date or datetime data type, this Snap uses the yyyyMMdd format to convert the field value. | N/A | 20210309 | |||||||||
| Export Parameters | Use this field set to specify the values to be returned as export parameters to the RFC function. Click
| ||||||||||||
| Export Parameter Name | String/Expression/Suggestion | Specify the export parameter name. Alternatively, click the Suggestion | N/A | Response | |||||||||
| Export Parameter Value | String/Expression | Specify the return value for the defined parameter. You can enter a static value or a dynamic value using an expression, or you can enter specific columns, such as $key from the output document. | N/A | 123
| |||||||||
| Execution Mode | Drop-down list | Select an option from this list to determine how this Snap should handle the SAP function module. The available options are:
| Pass Through Parameters | Trigger Child Pipeline | |||||||||
| Pipeline | String/Expression/Suggestion | Activates when you select Trigger Child Pipeline in the Execution Mode field. Specify the name of the Pipeline to be executed. Upon execution, this Snap uses the import parameters to trigger the Child Pipeline and passes the output to the SAP server. | N/A | RFC Pipeline | |||||||||
| Import Parameter Mapping | Activates when you specify or select a Pipeline in the Pipeline field. Use this field set to define the mappings between the RFC import parameters and the Pipeline parameters that are defined in the child Pipeline. This field set contains the following fields:
| ||||||||||||
| Function Parameter Name | String/Expression/Suggestion | Specify the import parameter that is defined in the RFC function. Alternatively, click the Suggestion | N/A | Quantity | |||||||||
| Pipeline Parameter Name | String/Expression/Suggestion | Specify the destination parameters for the Pipeline selected in the Pipeline field. Alternatively, click the Suggestion | N/A | Export_Date | |||||||||
| Child Pipeline Properties | Use this field set to define the properties for the child Pipeline. The field set contains the following fields:
| ||||||||||||
| Execute On | Drop-down list | Select the Snaplex location on which to execute the child Pipeline. The available options are:
| SNAPLEX_WITH_PATH | groundplex4-West | |||||||||
| Snaplex Path | String/Expression | Specify the path to the Snaplex that should be used to execute the child Pipeline. Leave the field empty if you want to execute the child on the same node as that of the parent Pipeline. | N/A | userplex-1 | |||||||||
| Reuse executions to process function | Check boxCheckbox | Select this check box to allow execution of a child Pipeline, and to pass multiple inputs to the Pipeline. Reusable executions continue to run until all the incoming function requests in the Snap are fully processed.
If you do not select this option, a new Pipeline execution is created for each incoming function. | Deselected | Selected | |||||||||
| Pool Size | Integer/Expression | Specify the maximum number of Pipelines to execute concurrently. If the value of Pool Size is greater than one, the Snap starts Pipeline executions according to the specified pool size.
| 1 | 4 | |||||||||
| Timeout | Integer/Expression | Specify the maximum number of seconds for which the Snap must wait for the child Pipeline to complete the runtime.
| N/A | 10 | |||||||||
| Retry Limit | Integer/Expression | Specify the maximum number of connection retry attempts in case of a connection failure in the child Pipeline execution. A retry happens only when the previous attempt resulted in an error. If the retry attempts exceed the configured value, the Pipeline execution fails, and an error message is displayed. | N/A | 10 | |||||||||
| Retry Interval | Integer/Expression | Specify the number of seconds to wait before retrying after a failure in the execution of the child Pipeline. | N/A | 10 | |||||||||
| Advanced JCo Server Properties |
| ||||||||||||
Property Name | String |
| N/A | jco.pool.maxconn | |||||||||
| Property Value | String |
| N/A | 15* | |||||||||
| Snap Execution | Drop-down list | Select one of the three modes in which the Snap executes:
| Validate & Execute | Execute only | |||||||||
...
The output of the SAP RFC Listener Snap contains the key outstructure, which reflects the logical key of the business object in the ABAP object program.
Child Pipeline
Next, we configure the child Pipeline with two Mapper Snaps. In the first Mapper Snap, we configure the Mapping table with Date.now() expressions for Bill date and Load date to display the current dates in the output.
