What are the limitations of Time-dependent workflow in Salesforce?

Hi,

Limitations of the workflow - 
The workflow feature is only available in Enterprise, Unlimited, Performance, and Developer editions. For the Professional Edition, you can enable this feature after paying an extra amount. As Salesforce is based on a multitenant architecture, it imposes a few limitations on the workflow:

• For each workflow rule, you can have the following:

10 time triggers
40 immediate actions
40 time-dependent actions per time trigger

• For both immediate and time-dependent actions in one workflow rule,
there can be no more than:

10 email alerts
10 tasks
10 field updates
10 outbound messages

• The workflow time trigger per hour limit for different editions are as follows:
Professional Edition: 250
Enterprise Edition: 500
Developer Edition: 50
Unlimited and Professional Edition: 1,000

• The workflow e-mail limit per day is as follows:

1,000 per Salesforce standard license
200,000 per organization

Note: Once an organization's daily e-mail limit of 200,000 exceeds, Salesforce will send a warning e-mail to the default workflow user and discard all the e-mails. Salesforce does not try to resend them later.

Hope this helps.

Adding some more points -

The workflow rule is active. The workflow rule is deactivated but has pending actions in the queue. The workflow rule evaluation criteria is set to Evaluate the rule when a record is: created, and every time it's edited. The workflow rule is included in a package

Hi,

When defining time dependent workflows in salesforce we have to use standard and custom date and date/time fields defined for the object.

We have to specify time using days and hours.
Also add actions to existing time triggers.

Thanks
