How to access previous value of "state" field in workflow

[Roshani]

Hi All,

I have a workflow running on HR payroll table . I want to set the "state" field to its previous value . How can I write in workflow . Below code i am using now, its seems not working 

current.state = workflow.scratchpad.state;
current.update();

Hi Roshani,

Use a run script in workflow and save the state value before it changes in a scratchpad, using:

 workflow.scratchpad.state = current.state;

Now you can access this value anywhere in the workflow using 'workflow.scratchpad.state'.

Thanks
