click the 'Find Workflows' button.
移动到PowerFolder控制台，打开'Administer'.在'Existing Workflows'部分下，
单击'Find Workflows'按钮.
Now that you are at the 'PowerFolder Query Workflows' web page, change the contents of
'Query' to '*APP* = 'SubmitInvoice'' (note that you should surround SubmitInvoice with single
quotes) and 'Output' to '*ID*,*APP*,*STATUS*' (pay attention to letter case and don't use any
spaces!), then click 'Submit'.
现在你处于 PowerFolder工作流查询页面，更改'Query'的内容为'*APP* =
'SubmitInvoice''(注意你应当用单引号来环绕SubmitInvoice）而且'Output'的内容为
'*ID*,*APP*,*STATUS*'，注意字符的大小写而且不要使用任何空格，然后单击
'Submit'(提交).
You should see two listings - the workflow that was 'AutoApprove'd and the one that required
accounting's approval. The listing should contain a unique id (each workflow gets its own),
'Submit' for the script name, and 'DONE' for its status.
你将看到两个列表-自动批准的工作流和需要财务批准的工作流。列表应该包括一个
唯一的ID(每个工作流有自己的ID), SubmitInvoice 是脚本名称，DONE是它的状态。
Now click the 'Snapshot' button. This will open a new window which will allow you to get much
more detail about the current state of this workflow.

'Paper', 'Toner', and 'Total'. Under 'Script' click 'View Graph' and 'View Summary' to get a nice
pictorial and written summary of the script. Click 'Trigger' to see the data (XML) that actually
started the process. The XML has much more information - quantities for pencils, paper, and
toner. Finally, click 'History' and you should see just one trace (no 'branches'). Comparing the
traces of each workflow will show a different path taken.
