Hi,

With early delta initialization, you have the option of writing the data into the delta queue or into the delta tables for the application during the initialization request in the source system. This means that you are able to execute the initialization of the delta process (the init request), without having to stop the posting of data in the source system. The option of executing an early delta initialization is only available if the DataSource extractor called in the source system with this data request supports this.

Hi Sreeni,

Prerequisites

You have configured the DataSource for the delta loading process. For more information, see Enabling Delta Load.

Procedure

1. Starting Delta Initialization

1. Launch the SAP BW Administrator Workbench and go to Modeling.

2. From the Modeling pane, click InfoSource to populate the InfoSource pane and select the InfoPackage you created for the InfoSource in, for example, Example of Data Extraction.

3. From the Update tab page, activate the Initialize Delta Process indicator.

4. To define parameters to be used for the delta load process, go to the Data Selection tab page and define relevant parameters.

5. In the Schedule tab page, choose Start to begin delta initialization.

If you defined parameters to be used in delta load (step 4 above), use PSA in the modeling component of Administrator Workbench to view the request results.

6. To check when delta initialization is finished, go to the Maintain InfoPackage screen of the Monitor – Administrator Workbench and press F6.

2. Monitoring Delta Initialization

1. Launch the BW Delta Queue Maintenance and select the DataSource in question.

2. Use the secondary mouse button to see the current pointer value in Generic Delta Current Status.

3. You can delete the delta initialization (if you want, and subsequently create a new delta initialization) in Scheduler (Maintain InfoPackage) by choosing the delta request from Initialization Options For Source System and choosing Remove.

In this screen, you can also check the status of the delta initialization request.

To see the content and results of the delta initialization request, go to PSA in the modeling component of Administrator Workbench to view the request results.

3. Running Delta Load

You can run the delta load process only after delta initialization has been completed.

1. Open the InfoPackage and in the Update tab page activate the Delta Update indicator.

2. Go to the Schedule tab page and choose Start.
