This is main task definition which is calling another workflow named "Bulk Inactive WWID Deletion" as Async process.
<Action id='1' name='Create Process View' application='com.waveset.session.WorkflowServices'>
<Argument name='op' value='createView'/>
<Argument name='type' value='Process'/>
<Argument name='endUser' value='true'/>
<Argument name='viewId' value='Process'/>
<Argument name='process' value='Bulk Inactive WWID Deletion'/>
<Argument name='authorized' value='true'/>
<Argument name='wwidFilePath'>
<ref>wwidFilePath</ref>
</Argument>
<Return from='view' to='processview'/>
</Action>
<Action id='2'>
<expression>
<block name='setName'>
<set name='processview.task.taskName'>
<concat>
<s>InactiveWWIDDeletion</s>
<s>:</s>
<ref>displaydate</ref>
</concat>
</set>
<set name='processview.task.execMode'>
<s>async</s>
</set>
</block>
</expression>
</Action>
<Action id='3' name='Checkin Process View' application='com.waveset.session.WorkflowServices'>
<Argument name='op' value='checkinView'/>
<Argument name='view' value='$(processview)'/>
<Argument name='endUser' value='true'/>
<Argument name='authorized' value='true'/>
</Action>
<Transition to='end'/>
<WorkflowEditor x='231' y='279'/>
</Activity>
Another Task Workflow will create a Deprovision View to Unassign LDAP resource and set email address to null.
