Hi tssivakumar,

You will have to add a textbox on your approver view (Multi-Line) and on the Submit you will have to write the comments to a SmartObject.

My suggestion here would be to create a SmartObject as follows:

Name: MyWorkflowComments

Fields:

ID (Autonumber)

Comment (Memo)

ExpenseID (Number)     **NOTE: This field name should be something to identify the current Process, in case of a Leave Request you will make this a LeaveRequestID, etc

SubmittedBy (Text)

SubmittedDate (DateTime)

Then on the Submit Rule, before you action your workflow, run the SmartObject Create method and set the following values:

ID: No value - This is autonumber

Comment: The Comment text box

ExpenseID: This is the field to identify the current process or item

SubmittedBy: The current user that submitted the comment

SubmittedDate: Current Date and Time
