Working with Data Fields

Data Field, which is also known as Process Variable, helps Process Pipelines to access and store information from outside application. Often the process flow is based on the value of this information. In other cases, this information is the result of running the tasks in the Pipeline.

Adding Data Field

From the Process Modeller window, click corresponding to the Pipeline for which you want to add a Data Field. The Process Flow tab is displayed..
Select the Data Fields tab.
Click Add. The Data Field Details window is displayed.
Enter the details as given in the table:

Field	Description
Data field Code	Enter the Variable Name/Code, which needs to be used by application to read or write in to this variable. This field is non translatable.
Data field Description	Enter a brief description of the Data field.
Data field Type	Enter the Data Field type. The supported types are String, Integer, Int, Float, AOM (Application Object Model), and Boolean. For more information on where we use AOM Data Field type, see AOM Data Field section.
Initial Value	Enter the default value for the Data.
Is Mandatory	This field is applicable for Data Field Type of AOM. By default, for AOM Data Field, this is selected as Yes. Select No if you do not want this parameter to be displayed as Execution Parameter for the Run Pipeline.
Scope	Select the scope of the Data Field from the drop-down list. The options are: Process- Select Process if you want to use the Data Field only in the current process. Package- Select Package if you want to use the Data Field across all the processes in the package.

Click OK.

System Data Fields

Some data are tracked internally by the System using a predefined set of Data Fields such as Status of Process. You can access these activity instance attributes in the same way you access regular data objects, but you cannot assign them new values.

System Data Field	Description
WF_RUNSK	Holds the Runsk value.
WF_MISDATE	Holds the MIS date.
WF_INFODOM_CODE	Holds the Information domain code.
WF_USERID	Holds the UserId who invoked the Workflow.
WF_LOCALE	Holds the locale.
WF_OBJECT_NAME	Holds the Object name.
WF_INSTANCE	Holds the Process Instance Id.
WF_SEGMENT_CODE	Holds the Segment Code.
WF_PROCESS_ID	Holds the Process Id.
WF_OUTCOME_ID	Holds the Outcome Id.
WF_OBJECT_ID	Holds the Object Id.
WF_ENTITY_ID	Holds the Entity Id.
WF_OBJECT_TYPE	Holds the Object Type.
WF_TASK_STATUS	Holds the Task status.
WF_TASK_RESPONSE	Holds the Task response.
WF_CALLBACK_TASK_STATUS	Holds the callback Task status.
WF_STATUS	Holds the current state of the Workflow. For example, Draft, PendingApproval and so on.

AOM Data Field

The AOM Data Fields are automatically created from the entries in the AAI_AOM_APP_COMP_ATTR_MAPPING table. These Data Fields, which are marked as mandatory, will be displayed in the Select Run Parameters window while executing Run Pipeline. For configuring AOM Data Fields, see Configuring Application Object Model (AOM) section.
