CDS Flow

The CDS Flow tab contains settings related to the source CDS View in SAP.

CDS View

The CDS View section displays the name, description and delta support of the selected CDS View.

Select CDS View

Select a CDS View from the connected SAP system. The CDS Flow service type extracts data from the selected CDS View. For more information, see Look Up CDS Views.

Output Columns

The Output Columns section shows which CDS View columns are included in the output of the service. You can select either all or only individual columns. By default all columns are selected and included in the output. Deselect the columns you want to remove from the output.

Update Mode

The Update Mode section contains settings that define the load behavior of the service. The CDS Flow service type offers the following loading behaviors:

Update Mode Description
Full Load Loads all data from the source CDS View.
Initial load Initializes delta loading.
Delta load Loads data that has been added or changed in the source CDS View since the last service run.

For more information, see Initialize Delta Loads.

Subscription Name

The subscription name is used to track changes in the source CDS View and must be unique for each CDS View. The subscription name is required for delta loading and is only visible when the update mode Delta Load is selected.

Subscribe

Initializes delta loading for the selected CDS View. If the initialization is successful, a status message "Initialization successful" opens in the bottom right corner of the window. After subscribing, the service must run once to complete the initial full load of the CDS View.

Subscription ID

The subscription ID is generated by SAP when delta loading is initialized and is used to identify the subscription for the selected CDS View in SAP. The subscription ID is only visible when the update mode Delta Load is selected.

Unsubscribe

Deletes the subscription for the selected CDS View. If successful, a status message "Unsubscribed successfully" opens in the bottom right corner of the window and the subscription ID is removed from the Subscription ID field

Service Settings

The Service Settings tab contains settings specific to the service type.

Package Size

The extracted data is split into packages of the defined size. The default value is 50000 lines.
A package size between 20000 and 50000 is advisable for large amounts of data. 0 means no packaging. Not using packaging can lead to an RFC timeout for large data extractions.

Warning

RFC_ERROR_SYSTEM_FAILURE - No more storage space available for extending an internal table
To avoid a memory overflow on the SAP source system and to avoid huge overheads, choose a package size that suits your memory capacity.

Destination Settings

The Destination Settings tab contains settings specific to the destination assigned to the service.

The destination settings define how and where a service saves its output data. The settings vary depending on the destination.
