SAP_DELTAQ

Overview

SAP_DELTAQ is the source type for SAP delta queue sources. In the repository seed data it is stored as SAP_DELTAQ with SourceTypeID = 3 and the description SAP delta queue.

Function

When SAP_DELTAQ is selected on an SAP connector, AnalyticsCreator shows the SAP DeltaQ/ODP panel in DeltaQ mode. The panel stores the extractor, update mode, auto sync flag, DeltaQ type, log destination, and RFC destination for the source.

SAP_DELTAQ is only offered for SAP connectors. CSV connectors are limited to Table, SAP connectors offer Table, SAP_DELTAQ, and SAP_ODP, and generic non-SAP connectors exclude SAP_DELTAQ.

Access

Use the source read flow on an SAP connector to create a SAP_DELTAQ source, or open an existing source and set the Type field to SAP_DELTAQ on the Define source page.

14NullableMarks whether the source column can contain null values.
15PK Ordinal PositionPrimary-key position when source metadata provides a key.
16AnonymizeAnonymization option. Values come from the COLUMNS_ANONYMIZATION_TYPES parameter, with a fallback of no and yes.
17Friendly nameFriendly column name, often filled from SAP text metadata when available.
18Display folderOptional display folder for downstream model organization.
19Referenced columnOptional reference to another source column.
20ReferencesReference metadata associated with the source column.
21Short text / Medium Text / Long textSAP text columns shown for SAP connectors and saved with imported DeltaQ column metadata.
22SAP DeltaQ/ODPPanel shown when SAP_DELTAQ or SAP_ODP is selected on an SAP connector.
23ExtractorDeltaQ extractor name stored in the SAP_DQ_Extract field.
24ModeUpdate mode selected from SAP_DELTAQ_UPDATEMODES, such as F - Full, D - Delta Updates, C - Delta Initialisation, S - Delta Init (without data), R - Repeat, I - Generate Initial Status, A - Activate (don't extract), or V - SSIS Variable.
25Auto sync.Stores the SAP_DQ_AutoSync flag. The read-source wizard also persists this choice in the SAP_DELTAQ_AUTOSYNC parameter.
26TypeDeltaQ type selected from SAP_DELTAQ_TYPES, including attributes, transactional data, text, hierarchy nodes, datasource append, or operational data store.
27Log.DestinationSAP logical system. When the connector has a connection string, the list is read from SAP; otherwise the field remains editable.
28RFC DestinationSAP RFC destination. When selected from SAP metadata, the matching RFC URL is stored with the source.
29ConstraintsOpens constraints for an existing source.
30CancelReturns to the previous page without saving changes.
31SaveSaves the source. The editor requires a source name and connector; the read-source wizard additionally requires Log.Destination, Mode, and RFC Destination for DeltaQ creation.

Read-source behavior

In the read-source wizard, SAP connectors expose the Tables, DeltaQ, and ODP selectors. The seed parameter DWHWIZARD_SAP_DELTAQ controls whether DeltaQ search is enabled by default.

For a new SAP_DELTAQ source, AnalyticsCreator stores the selected update mode, log destination, RFC destination, RFC URL, DeltaQ type, extractor, transfer mode, and auto-sync flag. Transfer mode is saved from the IDoc or tRFC choice and persisted in the SAP_DELTAQ_TRANSFERMODE parameter.

List behavior

The Sources list shows Source Schema, Source Name, Connector, Type, Path, Friendly name, and Description. Its search box matches description, connector name, source schema, and source name. Double-click opens the selected source in the Define source page.

Source actions

The source tree exposes source actions such as Edit source, Delete source, Add import, Add export, Refresh structure, Preview data, and Show reference diagram. SAP DeltaQ preview is blocked by the SAP preview logic with the message Cannot preview DeltaQ.
