([<SalesStage>] = "01 - Requirements")
& then 2 actions 1st "Wait" & then "Send mail" somehow its not working.Please guide where i am getting wrong..

Answer 1

Let me understand your business case: You need to send ONE email to the manager of the opportunity owner, if the Sales Stage = '01 - Requirements' for more that 30 days.
You need two workflows and a unused/custom field (a boolean field is preferred). Both workflows are similar. The first workflow is based on the event - When new record saved. This workflow will be invoked as soon as a new opportunity is created. The second workflow is invoked whenever the opportunity is modified using the event - When modified record saved. Any user who has edit rights to the opportunity could modify the opportunity but not change the sales stage. This results in an unpleasant situation where the manager could be flooded with emails. That's where we use the boolean field to protect against multiple updates and ensure a single email is sent after 30 days if the sales stage is still '01 - Requirements'
Workflow 1
Record Type: Opportunity
Event: When new record saved
Condition:[<SalesStageId>] = "12ASA-XCD34" AND ([<IndexedBoolean0>] IS NULL OR [<IndexedBoolean0>] = "N")
Note:
1. IndexedBoolean0 is the field named Indexed Checkbox in the list of fields
2. I have used the sales stage id. You have to find out the sales stage id for '01 - Requirements' and use it here.
Workflow 1 - Actions (remember to activate all actions and workflows)
1. Action = Wait
Period= 30 days
Reevaluate Rule Conditions After Wait = Y
2. Action = Field Update After Wait
Field Name = Indexed Checkbox
Value = "Y"
Overwrite Existing Values = Y
3. Action = Email
From > Specific Email Address> "[email protected]"
To > Relative User On Record > Opportunity Owner's Manager
Repeat this workflow configuration for Workflow 2, where the only difference is the event which should be When modified record saved
Exposing the Indexed Checkbox on the opportunity detail page layout for all users is optional (not recommended). It might be a good idea to expose this checkbox on the opportunity detail page for the administrator role only... so that he/she can take corrective action if an email is not sent after 30 days.
