How to retrieve an activity ( mapping, process flow, …) in a process flow ?
You can do that with the OWB - Public Views (metadata). Here below an example for a mapping :
select PACKAGE_NAME,
ALL_IV_PROCESS_ACTIVITIES.PROCESS_NAME,
ALL_IV_PROCESS_ACTIVITIES.ACTIVITY_NAME,
ALL_IV_PROCESS_ACTIVITIES.ACTIVITY_TYPE
from ALL_IV_PROCESS_ACTIVITIES,
ALL_IV_PROCESSES
where ALL_IV_PROCESS_ACTIVITIES.BOUND_OBJECT_NAME = 'NameofTheMapping'
AND ALL_IV_PROCESS_ACTIVITIES.PROCESS_ID = ALL_IV_PROCESSES.PROCESS_ID
Activity
Which type of activities can I have in a process flow ?
| ACTIVITY_TYPE | Description |
|---|---|
| PlSqlMapProcessNoteTag | Mapping |
| SUBPROCESS | Sub Process |
| ProcedureProcessNoteTag | Procedure |
| FunctionProcessNoteTag | Function |
| ABAPMapProcessNoteTag | Abap Mapping (batch_mapping) |
Fork
You can use the Fork activity to launch multiple, concurrent activities after the completion of an activity.
Return statuses
User Defined Objects Activity
configuration properties “Use return as Status”:
- enabled then values for return statuses are :
- 1 - SUCCESS
- 2 - WARNING
- 3 - ERROR
- disabled then value
- 0 means SUCCESS
- and non-zero - ERROR.
As a workaround, you can define processflow variable and bind RESULT_CODE parameter of Sql*plus activity to this variable. Then you can define transition from sqlplus activity with custom (“complex”) condition (like PF_VAR_RC=2 etc.).
Function
Create a function which return as Status to return 1, 2 or 3 to direct the process flow into SUCCESS, WARNING or ERROR respectively.
