6.6.3 Sequencing Runs

To sequence the runs using auto-sequencing or manual sequencing:

1. Login to STSA.
   The Workspace Summary page is displayed.
2. In the Workspace Summary, Sandbox tab, launch the required workspace.
3. Click Analysis Configuration.
   The analysis configuration summary page is displayed.
4. Click the required analysis configuration.
   The Review & Validate screen is displayed.
5. Click Process on the right-hand side.

   The Process page and the selected composite pipeline is displayed.

6. Click actions against the pipeline and click View.
   The Process Pipeline page is displayed.
7. By default, the Auto Sequence option is selected and the runs are listed as per the default sequence.
8. (Optional) To sequence the runs manually, click Manual Sequence.
   1. Under Reorder column, drag and drop the processes as per your requirement.
9. (Optional) To reset the order to the default auto-sequence mode, after changing the sequence manually, click the Auto Sequence option.
10. To save your selection, click Save and Close.
    A successful message is displayed.
11. (Optional) After rearranging the sequence manually, if you want to switch back to the auto-sequence mode, click the Reset option.

    Note:

    In case of PMF mode, the auto-sequencing mode works only for the processes that are part of the composite pipeline that was created automatically. If you have added new processes through the Add New Processes screen, then these process are listed at the end of the list.

    Note:

    In case of Data Catalog (DC) mode, the processes are run in sequence as mapped in DC.
    A glossary term on the data catalog has an input and output sub-glossary term. These sub-glossary terms are tagged to processes and models.

    For example, Glossary terms A, B and C have input sub-glossary terms as Input_A, Input_B, Input_C and Output_A, Output_B and Output_C respectively.

    These sub-glossary terms can be tagged to processes and models on the data catalog.

    Assuming input_A is tagged to process A, process C and process D and 
    output_A is tagged to process B. 
    Input_B is tagged to process C, and output_B is tagged to process B.
    Input_C is tagged to process A and process D and output_C is tagged to process C.
    Input_D is tagged to proceed D and output_D is tagged to process A.
    
    

    This is represented in the below image.

    Then, the processes are sequenced as below:

    First process B is executed and then process C is executed followed by process A and finally process D is executed. The auto-sequencing is in this particular order since process B is not dependent on any inputs (or process) and can start immediately. However, process C has a dependency on process B (since the output of process B is an input to process C). Similarly, process A cannot run independently as it requires inputs from process C and process A's outputs are an input to process D.

    The sequence of process is as per the below image:

    To configure the component value (PMF or DC mode), refer to the EST_CONFIGURATION table mentioned in the Populating tables for Composite Pipeline components section.

12. To save the changes made, click Save and Close.
    A successful message is displayed. Click OK. The process section is displayed.

    Note:

    Ensure that you save your changes and then exit the screen if you are changing the sequences manually.
