The Extraction Process object handles the transformation of the data. The transformation is executed between acquiring the data through (Glue-2008) Fetcher and storing the data through (Glue-2008) Consumer.

The Extraction Process also allows the execution of extraction and monitoring of launched extractions.

How to Create an Extraction Process Object

Run the transaction /DVD/GL80 to open (Glue-2008) Object Navigator
In the context menu of the desired package select the option Create Extractor 2.0 object
Enter the name of the new Extraction Process under Object name and a short description about it under Description
Select Extraction Process under the Component type dropdown and under Component implementation leave the default implementation
Confirm the popup

Activation of an Extraction Process

After the creation, the object is in the saved state.

Additional Functionalities of Extraction Process

The Extraction Process provides a few other functionalities on top of the Common functionalities of Extractor 2.0 objects.

Execute extraction
- button in (Glue-2008) Object Navigator toolbar
- execute the report generated by the activation of Extraction Process
- for more information see Execute extraction
Monitor
- button in (Glue-2008) Object Navigator toolbar
- option in the floating menu of Extraction Process
- display detailed information for each executed extraction of the current Extraction Process
- for more information see Monitor

Execute Extraction

Execution of the extraction is done by the pre-generated report, based on the Execution Process. Therefore each report can contain different input parameters.

The pre-generated report has an execution button and can have 5 sections of inputs:

Execution type - selection of execution type
- Standard Execution
- Mass Execution
Basic parameters - section for general settings of the extraction
- Preview mode
  - when enabled, data will be not written to the target but only the sample will be displayed on the screen
- Package size
  - number of rows selected for each package of package based source
- Package size MB
  - input for a number of MB, with compute button Calculate
Selection filter - the section is generated based on the selection in the specific (Glue-2008) Fetcher
Additional Fetcher config - section generated for editable parameters of the (Glue-2008) Fetcher
- Load type
  - a dropdown of all available Load types
- Use cursor
  - when enabled, data from the source will be processed by the packages
Additional Consumer config - section generated for editable parameters of the (Glue-2008) Consumer
- Data validation (only for Glue consumers)
  - when enabled, the data extracted to the storage will be validated with the source data. To make the checkbox visible in the extraction process, turn on the parameter ENABLE_DATA_VALIDATION in Glue settings (transaction /DVD/GL_SETT).
- Truncate target
  - when enabled, all data will be deleted from the target before writing from the source

By clicking on the execute button a pop-up will appear with a cancel button and two buttons for execution type:

Dialog - the extraction will be executed in a dialog process
Background - another pop-up with a schedule will be displayed and after the confirmation, the extraction will be executed in the background process

Monitor

The Monitor provides detailed information about each executed extraction of the current Extraction Process:

Request - unique identification of an execution
Name - name of the Extractor 2.0 object
Mode - mode in which the execution was executed (Dialog/Background)
Status - icon which indicates in which state the execution is
- Running - red truck
- Success - green square
- Failed - red circle
- Error - yellow flash
Display logs - button, displays detailed information about an execution flow of the extraction
User - name of the user which executed the extraction
Start date - start date of an execution
Start time - start time of an execution
Runtime - duration of extraction in seconds
Rows read - number of read rows
Rows written - number of written rows
Delta mode - indicates used load type
Delta - indicates delta type used
Selection - button shows defined selection for mass execution
Variant - used variant
Variant description - description of used variant
Action - in case of a failed request, you can restart request via a button in action column
Test mode - indication if the extraction was executed only in a test mode
