Definition

This field indicates which delta procedure is used by the DataSource.

The delta procedure is characterized by the following properties:

  • Record typeof extracted records:

    The record type describes the type of data records transferred from the DataSource to the BI in a delta procedure:

    DataSource returns Full (complete data set of source)
    DataSource returns Before Images (status of records before the change)
    DataSource returns Before Images (status of records before the change)
    DataSource returns Delta Images for values that cannot be totaled (After Images for values that cannot be totaled)
    DataSource returns Deletion records (only key values)
    DataSource returns complete deletion records (Reverse Images)
    DataSource returns New images (new records)
  • Delta type (type of request and transfer in SAP source system):

    This property is only relevant for SAP source syetems. The delta type describes how new and changed data records are added to the delta queue in the SAP source system.

    Delta using delta queue: The application (or extraction using function module) delivers the delta to the generic delta queue, where the delta is retrieved from the DataSource by means of a request from the BI.
    Delta using extractor: The DataSource extractor returns the delta (requested from the BI) and stores it in the delta queue, in case an error occurs and the transfer needs to be repeated.
    Delta using ALE change pointer for master data
  • Serialization request:

    This property indicates whether changes made to document data have to be in the same order as in the source system.

    Serialization not required
    Serialization of request required
    Serialization of data packages required

Use

For DataSources from SAP source systems, the system displays the delta procedure specified in the source system.

Delta Procedure    Description    Record type    Delta type    Serialization    Purpose    Example/Explanation

-    Full upload (Delta only by using InfoPackage selections)    F    -    by request:    InfoCube, DataStore Object, InfoObject

A    ALE change pointer (master data)     A    ALE    by package:    only master data

ABR    Complete delta with deletion flag using delta queue     N,B,A,R    Queue    by package:    InfoCube-capable

ABR1    Like 'ABR' procedure but serialization is only by request    N,B,A,R    Queue    by request:    InfoCube-capable

ADD    Additive extraction using extraktor    D    Extractor:    by request:    InfoCube-capable     LIS infostructures

ADDD    Like 'ADD' but using delta queue    D    Queue    by request:    InfoCube-capable

AIE    After images using extractor    A    Extractor    by package:    only DataStore object    FI-GL, AP, AR

AIED    After images with deletion flag using extractor    A,L    Extractor    by package:    only DataStore object    FI-GL, AP, AR

AIM    After images using delta queue    A    Queue    by package:    only DataStore object    FI-AP, AR

AIMD    After images with deletion flag using delta queue    A,L    Queue    by package:    only DataStore object

CUBE    InfoCube extraction    D    Extractor    No serialization    InfoCube    Export-DataSource of InfoCube   

D    Unspecific delta using delta queue    -    Queue    by package:    only InfoCube

E    Unspecific delta using extractor    -    Extractor    by package:    only InfoCube

NEWD    Only new records (inserts) over delta queue    N    Queue    No serialization    InfoCube-capable

NEWE    Only new records (inserts) over extractor    N    Extractor    No serialization    InfoCube-capable

ODS    DataStore object extraction    N,B,A,R    Extractor    by package:    DataStore object, InfoObject-capable    Export-DataSource of DataStore object

For file, UD connect, DB connect, and Web service DataSources you can select the following delta procedures:

Delta procedure    Description    Record type    Delta type    Serialization    Purpose    Example/Explanation

-    Full upload (Delta only by using InfoPackage selections)     F    -    by request:    InfoCube, DataStore Object, InfoObject    You can make selections by using the date, for example.

FIL0    Delta data (after images)    A    -    by package:    DataStore object    Each record to be loaded provides the new status for all key figures and characteristics.

FIL1    Delta data (delta images)    D    -    by package:    DataStore object, InfoCube    The record to be loaded for additive key figures provides only the modification to the key figure.

Examples

AIM (After images using delta queue):

This delta procedure used for DataSources from SAP source systems only sends After images. Therefore delta requests can only be used to update to a DataStore object. It cannot be directly updated to an InfoCube. The same key can be transferred multiple times within a request. Therefore it is necessary to serialize the data package by package. The delta records are written directly to the delta queue, where the records are retrieved from the BI by request. This procedure is used in FI-AP / AR to transfer the line items.

FIL0 (After Images):

This delta procedure only sends After images. Therefore delta requests can only be used to update to a DataStore object. It cannot be directly updated to an InfoCube. The same key can be transferred multiple times within a request. Therefore it is necessary to serialize the data package by package. This delta procedure is used by all source system types apart from SAP source systems. Therefore delta queues are not implemented: Delta data records are transferred directly from the source system to the DataSource in the BI.
