Calling a sub workflow

[superjames]

I would like to call a workflow from a workflow, but I need to set a different current record in the sub flow. I want the parent workflow to call the sub flow and wait for the return. I have been using the methodology from this: https://wiki.servicenow.com/index.php?title=Using_Subflows

This calls the sub flow and waits for completion, but does not set the current record in the sub flow, so I pass the record needed as input and use this code in the sub flow:

// Setup current record from input

    current = new GlideRecord('u_job_set');

    current.get(workflow.scratchpad.u_current_record);

    current.state = 1;

// Setup context

    context.table = 'u_job_set';

    context.id = current.sys_id;

    context.state = 'executing';

This works, but there are some timing issues, and I suspect there is more that needs to be done. I found this in the AWS workflows.

My other option is to have a run script that launches the workflow. This seems to work better in the sub flow, but does not wait for subflow completion:

var jobSet = new GlideRecord('u_job_set');

jobSet.get(workflow.scratchpad.cRecord);

var wf = new Workflow();

var vars = {};

var workflowId = wf.getWorkflowFromName('Sub Flow 1');

wf.startFlow(workflowId, jobSet, "", vars);

So, Is there a way to pause after the workflow launch here? I know I can do it with some business rules and database variables, but looking form something cleaner.

Or, is there a better way to set the current record in the first case? I am also using the parallel flow launcher and the WorkflowCoordinator object to launch subflows. These behave just like the first example.

I have a manager workflow that launches a Job Set subflow. The Job Set flow launches Job subflow.

The manager workflow inserts the job sets into the u_job_set table, and the jobs into the u_job table.

Each workflow uses its respective table. I want the flows to execute asynchronously (run and wait for completion).

The second example I have is from a runscript invoking a workflow. I am not sure what you mean by having them dependent on each other.

James,

What you can do is in your Parent Workflow after the Runscript which invokes the Workflow on Job table, have a Wait For Condition to wait for some flag like a custom field 'u_job_wait'.

Now, in the Workflow which is running on the Job at the end of the Workflow, update the record of the parent with u_job_wait to true which then will have the Workflow move forward.

I think this is going to work for me. It seems to solve my problems. Thanks!
