The Extraction Process object handles the transformation of the data. The transformation is executed between acquiring the data through (Glue-2002) Fetcher and storing the data through (Glue-2002) Consumer.

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

How to Create an Extraction Process Object

  1. Run the transaction /DVD/GL80 to open (Glue-2002) Object Navigator
  2. Right-click on the desired package and select the option Create Extractor 2.0 object
  3. Enter the name of the new Extraction Process under Object name and a short description about it under Description
  4. Select Extraction Process under the Component type dropdown and under Component implementation leave the default implementation
  5. Confirm the popup

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

Mandatory parameters to be filled before the activation

Mandatory buttons to click before the activation

  • Suggest Mapping
    • button in the toolbar of Transformation part 
    • generate mapping based on the filled Fetcher and Consumer

Optional inputs before the activation

  • Start Routine
    • button in Transformation toolbar for ABAP code editor
    • executed before the transformation part of the extraction
  • End Routine
    • button in Transformation toolbar for ABAP code editor

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
  • Monitor
    • button in (Glue-2002) 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 1463910427

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 4 sections of inputs:

  • 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 number of MB, with compute button Calculate
  • Selection filter - section is generated based on the selection in the specific (Glue-2002) Fetcher
  • Additional Fetcher config - section generated for editable parameters of the (Glue-2002) Fetcher
    • Load type
    • 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-2002) Consumer
    • Truncate target
      • when enabled, all data will be deleted from the target before writing from the source

On click of 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
  • 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 an extraction in seconds
  • Rows read - number of read rows
  • Rows written - number of written rows
  • Test mode - indication if the extraction was executed only in test mode
