Scheduling Data Archiving Processes Using Process Chains

You are in the Administration area in Data Warehousing Workbench. Choose Process Chains. The Process Chain Maintenance Planning View screen appears.

In the left-hand screen area of the required display component, navigate to the process chain where you want to insert your data archiving process and double-click to select it. The system displays the process chain plan view on the right of the screen.

If no suitable process chains are found, create a new one yourself. More information: Creating Process Chains.

On the left of the screen, choose Process Types. The system displays the available process categories.

In process category Data Target Administration, choose application process type Archive Data from the InfoProvider.

Insert the application process type into the process chain by dragging it. The dialog box for inserting a process variant appears.

Create a process variant and confirm your entries. An additional dialog box appears.

Select your data archiving process.

Make the required settings:

• Under Process Flow Control, you can either resume unfinished archiving processes or specify whether a archiving process should only run until a specific status is reached. See Status of Archiving Request.

  With ADK-based archiving, you can only archive in the first process step up to status 40 Copy Data to Archive. You then also need a second variant to delete the data (see below).

• Under Relative Time Restrictions, you can precisely define the period to be archived. Using a relative time condition in the form of a minimum age allows you to schedule periodic archiving runs without having to adapt a variant with every run.

  The relative time restriction is changed into a selection condition for the time slice characteristic, depending on the start time of the write process. An intersection is created using the absolute time conditions for the time slice characteristic and the selection conditions for the other characteristics. This intersection is then used to derive the area that has already been archived and the selection conditions from other archiving requests that are still open. The resulting selection condition is stored with the newly created archiving request and is used for the subsequent selection of data in the write phase and the delete phase.

• Under Further Restrictions, you can select values for your partitioning characteristics.

Confirm your entries. At runtime for the process step, an archiving request is generated from this variant, which controls entire archiving session.

With ADK-based archiving, you also need a second process variant for this data archiving process. In this variant, select the option Continue Open Archiving Request(s) under Process Control. Then and only then can you select the status 70 Deletion Phase Confirmed and Request Completed.

Save and activate your process chain. The process chain starts according to the selections in the start process.
