Getting an process-flow audit id in the process flow itself

Question

Hi,
I am using OWB 11gR2 and want to capture the audit_id of the process flow itself at the process-flow level.
I want to use this to pass it tru to the mappings in the process flow.
I know how to get audit_id when you're in the mapping (get_audit_id), but i want the audit_id of the process flow when i am "inside" the process flow.
When i have this i can let all of my mappings in the flow receive the same id.
When i setup a parameter at the process flow and specify get_audit_id there it errors on me.
Does anybody what to specify here ?

Answer 1

ok,
i figured it out myself and answered myself in another thread.
Basically it goes like this:
In the master flow you have sub-processflow objects which you want to pass along the audit_id of the master flow.
So that you can pass along the same audit-id to every mapping in all of the flows.
But it would be nice to be able to run sub flows independently from the master flows (for testing etc.)but still feed the same id(whatever that is) to the mappings in that process flow.
And on the lowest level this applies to mappings as well: be able to run a mapping and get a id to store in a field.
The same applies to feeding a process date to all the mappings in your flows(used for dwh purposes)
How does this work on the mappings ?
Create a mapping input parameter, put 2 params in it.
One date, one number. The date part is easy: just put SYSDATE in it.
The number part would ideally hold get_audit_id as default value. Unfortunately this generates an error.
So put default value of 1 here. Create a constant on the mapping with value get_audit_id in it.
Create expression that tests if input_param has something else than 1 as the value ; if so then there was no audit_id fed into the mapping by a process flow. Make the expression use the constant then. Use the output of the expression in your mapping.
How does this work in process flows ?
You'll have two different parts here:
-feeding from flow to a sub-flow
-feeding from flow to mapping
Flow to subflow:
You can not bind a flowparameter to subprocess paramter so you'll need to create 2 variables.(process date / audit id)
Create two parameters, one date with sysdate as default, one number with 1 as default.
Use assign operator to bind audit_id parameter to the audit id variable.
Use another one to bind to the same variable, but specify parent_audit_id as value instead of binding it to the paramter.
Use conditonal routing on these two assign operators to have one of these be executed.
This will ensure that the variabel either gets parent_audit or the value of the input parameter of the flow.
Use another assign op. to bind the date input to the date variabel.
Bind the parameters of the sub flows to the variables.
Flow to mapping:
Use the same procedure as descibed above. Only difference here is that you can bind a mapping parameter to a parameter.
This means that you'll don't need the assign stuff for the date parameter since you can bind the date parameter of the mapping to the input parameter of the flow.
Hope this helps someone ...
